MC33887 5.0 A H-bridge with load current feedback Rev. 17 — 17 September 2018 1 Data sheet: technical data General description The 33887 is a monolithic H-bridge power IC with a load current feedback feature making it ideal for closed-loop DC motor control. The IC incorporates internal control logic, charge pump, gate drive, and low RDS(on) MOSFET output circuitry. The 33887 is able to control inductive loads with continuous DC load currents up to 5.0 A, and with peak current active limiting between 5.2 A and 7.8 A. Output loads can be pulse width modulated at frequencies up to 10 kHz. The load current feedback feature provides a proportional (1/375th of the load current) constant-current output suitable for monitoring by a microcontroller’s A/D input. This feature facilitates the design of closed-loop torque/ speed control as well as open load detection. It meets the stringent requirements of automotive applications and is fully AEC-Q100 grade 1 qualified. A fault status output pin reports undervoltage, short-circuit, and overtemperature conditions. Two independent inputs provide polarity control of two half-bridge totempole outputs. Two disable inputs force the H-bridge outputs to 3-state (exhibit highimpedance). The 33887 is parametrically specified over a temperature range of −40 °C ≤ TA ≤ 125 °C and a voltage range of 5.0 V ≤ V+ ≤ 28 V. Operation with voltages up to 40 V with derating of the specifications.

Brief non-repetitive excursions of junction temperature above 150 °C can be tolerated, provided the duration does not exceed 30 seconds maximum. Non-repetitive events are defined as not occurring more than once in 24 hours. [2] Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause malfunction or permanent damage to the device. [3] NXP’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow Temperature and Moisture Sensitivity Levels (MSL), go to www.nxp.com, search by part number (remove prefixes/suffixes and enter the core ID) to view all orderable parts, and review parametrics. [4] The limiting factor is junction temperature, taking into account the power dissipation, thermal resistance, and heat sinking. [5] Exposed heatsink pad plus the power and ground pins comprise the main heat conduction paths. The actual RθJB (junction-to-PC board) values will vary depending on solder thickness and composition and copper trace thickness. Maximum current at maximum die temperature represents ~ 16 W of conduction loss heating in the diagonal pair of output MOSFETs. Therefore, the RθJC-total must be less than 5.0 °C/W for maximum load at 70°C ambient. Module thermal design must be planned accordingly.

This is typically done by holding one input high while applying a PWM pulse train to the other input. The maximum PWM frequency obtainable is a compromise between switching losses and switching frequency. See Section 12. The maximum switching frequency during active current limiting is internally implemented. The internal current limit circuitry produces a constant OFF time pulse-width modulation of the output current. The output load’s inductance, capacitance, and resistance characteristics affect the total switching period (OFF time + ON time) and thus the PWM frequency during current limit. Output delay is the time duration from the midpoint of the IN1 or IN2 input signal to the 10 % or 90 % point (dependent on the transition direction) of the OUT1 or OUT2 signal. If the output is transitioning high to low, the delay is from the midpoint of the input signal to the 90% point of the output response signal. If the output is transitioning low to high, the delay is from the midpoint of the input signal to the 10 % point of the output response signal. See Figure 6. ILIM output constant OFF time is the time during which the internal constant OFF time PWM current regulation circuit has 3-stated the output bridge. Load currents ramping up to the current regulation threshold become limited at the ILIM value. The short-circuit current possess a di/dt that ramps up to the ISCH or ISCL threshold during the ILIM blanking time, registering as a short-circuit event detection and causing the shutdown circuitry to force the output into an immediate 3-state latch OFF. See Figure 10 and Figure 11. Operation in current limit mode may cause junction temperatures to rise. Junction temperatures above ~160 °C causes the output current limit threshold to progressively foldback, or decrease with temperature, until ~175 °C is reached, after which the TLIM thermal latch OFF occurs. Permissible operation within this foldback region is limited to nonrepetitive transient events of duration not to exceed 30 seconds. See Figure 9. ILIM blanking time is the time during which the current regulation threshold is ignored so that the short-circuit detection threshold comparators may have time to act. Rise time is from the 10 % to the 90 % level and fall time is from the 90 % to the 10 % level of the output signal. See Figure 8. Disable delay time measurement is defined in Figure 7.

Upon undervoltage recovery, status flag is reset automatically or automatically cleared and the outputs are restored to their original operating condition. When a short-circuit or overtemperature condition is detected, the power outputs are 3-state latched OFF independent of the input signals and the fault status flag is set logic low. 14 Functional description 14.1 Introduction Numerous protection and operational features (speed, torque, direction, dynamic braking, PWM control, and closed-loop control), in addition to the 5.0 A current capability, make the 33887 a very attractive, cost-effective solution for controlling a broad range of small DC motors. In addition, a pair of 33887 devices can be used to control bipolar stepper motors. The 33887 can also be used to excite transformer primary windings with a switched square wave to produce secondary winding AC currents. 14.2 Functional pin description 14.2.1 Power ground and analog ground (PGND and AGND) The power and analog ground pins should be connected together with a very lowimpedance connection. 14.2.2 Positive power supply (V+) V+ pins are the power supply inputs to the device. All V+ pins must be connected together on the printed circuit board with as short as possible traces offering as low impedance as possible between pins.

All rights reserved. 18 / 40 MC33887 NXP Semiconductors 5.0 A H-bridge with load current feedback V+ pins have an undervoltage threshold. If the supply voltage drops below a V+ undervoltage threshold, the output power stage switches to a 3-state condition and the fault status flag is set and the fault status pin voltage switches to a logic low. When the supply voltage returns to a level that is above the threshold, the power stage automatically resumes normal operation according to the established condition of the input pins and the fault status flag is automatically reset logic high. As V+ increases in value above 28 V, the charge pump performance begins to degrade. At +40 V, the charge pump is effectively non-functional. Operation at this high voltage level results in the output FETs not being enhanced when turned on. This means that the voltage on the output will be VOUT = (V+) – VGS. This increased voltage drop under load produces a higher power dissipation. 14.2.3 Fault status (FS) The FS pin is the device fault status output. This output is an active low open drain structure requiring a pull-up resistor to 5.0 V. See Table 9. 14.2.4 Logic input control and disable (IN1, IN2, D1, and D2) These pins are input control pins used to control the outputs. These pins are 5.0 V CMOS-compatible inputs with hysteresis. The IN1 and IN2 independently control OUT1 and OUT2, respectively. D1 and D2 are complementary inputs used to 3-state disable the H-bridge outputs. When either D1 or D2 is set (D1 = logic high or D2 = logic low) in the disable state, outputs OUT1 and OUT2 are both 3-state disabled; however, the rest of the circuitry is fully operational and the supply IQ(standby) current is reduced to a few milliamperes. See Table 9 and Table 7. 14.2.5 H-bridge output (OUT1, OUT2) These pins are the outputs of the H-bridge with integrated output MOSFET body diodes. The bridge output is controlled using the IN1, IN2, D1 and D2 inputs. The low-side MOSFETs have active current limiting above the ILIM threshold. The outputs also have thermal shutdown (3-state latch off) with hysteresis as well as short-circuit latch off protection. A disable timer (time tb) used to detect currents that are higher than current limit is activated at each output activation to facilitate hard short detection (see Figure 11). 14.2.6 Charge pump capacitor (CCP) A filter capacitor (up to 33 nF) can be connected from the charge pump output pin and PGND. The device can operate without the external capacitor, although the CCP capacitor helps to reduce noise and allows the device to perform at maximum speed, timing, and PWM frequency. 14.2.7 Enable (EN) The EN pin is used to place the device in a Sleep mode so as to consume very low currents. When the EN pin voltage is a logic low state, the device is in the Sleep mode. The device is enabled and fully operational when the EN pin voltage is logic high.

All rights reserved. 19 / 40 MC33887 NXP Semiconductors 5.0 A H-bridge with load current feedback An internal pull-down resistor maintains the device in Sleep mode in the event EN is driven through a high impedance I/O or an unpowered microcontroller, or the EN input becomes disconnected. 14.2.8 Feedback for H-bridge (FB) The 33887 has a feedback output (FB) for real time monitoring of H-bridge high-side current to facilitate closed-loop operation for motor speed and torque control. The FB pin provides current sensing feedback of the H-bridge high-side drivers. When running in forward or reverse direction, a ground referenced 1/375th (0.00266) of load current is output to this pin. Through an external resistor to ground, the proportional feedback current can be converted to a proportional voltage equivalent and the controlling microcontroller can read the current proportional voltage with its analog-todigital converter (ADC). This is intended to provide the user with motor current feedback for motor torque control. The resistance range for the linear operation of the FB pin is 100 < RFB < 200 Ω. If PWM-ing is implemented using the disable pin inputs (either D1 or D2), a small filter capacitor (1.0 μF or less) may be required in parallel with the external resistor to ground for fast spike suppression. 15 Functional device operation 15.1 Operational modes The 33887 (see Figure 2), is a fully protected monolithic H-bridge with enable, fault status reporting, and high-side current sense feedback to accommodate closed-loop PWM control. For a DC motor to run, the input conditions need be as follows: Enable input logic high, D1 input logic low, D2 input logic high, FS flag cleared (logic high), one IN logic low and the other IN logic high (to define output polarity). The 33887 can execute dynamic braking by simultaneously turning on either both high-side MOSFETs or both low-side MOSFETs in the output H-bridge; e.g., IN1 and IN2 logic high or IN1 and IN2 logic low. The 33887 outputs are capable of providing a continuous DC load current of 5.0 A from a 28 V V+ source. An internal charge pump supports PWM frequencies to 10 kHz. An external pull-up resistor is required at the FS pin for fault status reporting. The 33887 has an analog feedback (current mirror) output pin (the FB pin) that provides a constant current source ratioed to the active high-side MOSFET. This can be used to provide real time monitoring of load current to facilitate closed-loop operation for motor speed/torque control. Two independent inputs (IN1 and IN2) provide control of the two totem-pole half-bridge outputs. Two disable inputs (D1 and D2) provide the means to force the H-bridge outputs to a high-impedance state (all H-bridges switch off). An EN pin controls an enable function that allows the 33887 to be placed in a power-conserving sleep mode. The 33887 has undervoltage shutdown with automatic recovery, active current limiting, output short-circuit latch off, and overtemperature latch off. An undervoltage shutdown, output short-circuit latch off, or overtemperature latch off fault condition causes the outputs to turn off (i.e., become high impedance or 3-stated) and the fault output flag to be set low. Either of the disable inputs or V+ must be toggled to clear the fault flag. MC33887 Data sheet: technical data All information provided in this document is subject to legal disclaimers.

All rights reserved. 20 / 40 MC33887 NXP Semiconductors 5.0 A H-bridge with load current feedback Active current limiting is accomplished by a constant OFF time PWM method employing active current limiting threshold triggering. The active current limiting scheme is unique in that it incorporates a junction temperature dependent current limit threshold. This means the active current limiting threshold is ramped down as the junction temperature increases above 160 °C, until at 175 °C the current is decreased to about 4.0 A. Above 175 °C, the overtemperature shutdown (latch off) occurs. This combination of features allows the device to remain in operation for 30 seconds at junction temperatures above 150 °C for nonrepetitive unexpected loads. 15.2 Protection and diagnostic features 15.2.1 Short-circuit protection If an output short-circuit condition is detected, the power outputs 3-state (latch off) independent of the input (IN1 and IN2) states, and the fault status output flag is set logic low. If the D1 input changes from logic high to logic low, or if the D2 input changes from logic low to logic high, the output bridge becomes operational again and the fault status flag is reset (cleared) to a logic High state. The output stage always switches into the mode defined by the input pins (IN1, IN2, D1, and D2), provided the device junction temperature is within the specified operating temperature range. 15.2.2 Active current limiting The maximum current flow under normal operating conditions is internally limited to ILIM (5.2 A to 7.8 A). When the maximum current value is reached, the output stages are 3stated for a fixed time (ta) of 20 μs typical. Depending on the time constant associated with the load characteristics, the current decreases during the 3-state duration until the next output ON cycle occurs (see Figure 11 and Figure 14). The current limiting threshold value is dependent upon the device junction temperature. When −40 °C ≤ TJ ≤ 160 °C, ILIM is between 5.2 A to 7.8 A. When TJ exceeds 160 °C, the ILIM current decreases linearly down to 4.0 A typical at 175 °C. Above 175 °C the device overtemperature circuit detects TLIM and overtemperature shutdown occurs (see Figure 9). This feature allows the device to remain operational for a longer time but at a regressing output performance level at junction temperatures above 160 °C. 15.2.3 Output avalanche protection An inductive flyback event, namely when the outputs are suddenly disabled and V+ is lost, could result in electrical overstress of the drivers. To prevent this, the V+ input to the 33887 should not exceed the maximum rating during a flyback condition. This may be done with either a zener clamp and/or an appropriately valued input capacitor with sufficiently low ESR. 15.2.4 Overtemperature shutdown and hysteresis If an overtemperature condition occurs, the power outputs are 3-stated (latched off) and the fault status flag is set to logic low. To reset from this condition, D1 must change from logic high to logic low, or D2 must change from logic low to logic high. When reset, the output stage switches ON again, MC33887 Data sheet: technical data All information provided in this document is subject to legal disclaimers.

Important: Resetting from the fault condition clears the fault status flag. 16 Typical applications Figure 23 shows a typical application schematic. For precision high-current applications in harsh, noisy environments, the V+ bypass capacitor may need to be substantially larger.

The significant feature of these packages is the exposed pad on which the power die is soldered. When soldered to a PCB, this pad provides a path for heat flow to the ambient environment. The more copper area and thickness on the PCB, the better the power dissipation and transient behavior.
