All Rights Reserved. 12 MP6526 – HEX HALF-BRIDGE MOTOR DRIVER WITH SERIAL INPUT CONTROL OPERATION The MP6526 is a six-half-bridge motor driver that can drive up to six different loads with separate controls for high-side or low-side MOSFETs from a standard serial data interface. Serial Interface Data transfer starts with the falling edge of the CS signal (see Figure 2). Execution of new input data is enabled on the rising edge of the CS signal. Data must appear at DI synchronized to CLK and is accepted on the falling edge of the CLK signal. The LSB (bit0, SRR) must be transferred first. The output data at DO is enabled on the falling edge of CS. The output data changes state with the rising edge of CLK and remains stable until the next rising edge of CLK appears. When CS is high, DO is in a tri-state condition. The LSB (bit0, TP) is transferred first.

L L 14 MP6526 – HEX HALF-BRIDGE MOTOR DRIVER WITH SERIAL INPUT CONTROL Enable Control (EN) There are two ways to enable or disable the MP6526: 1. Controlled by software: set bit SE in the input register. Low = standby, high = normal operation. 2. Hardware enable (EN): low = standby, high = normal operation. In both cases, if the device is disabled, then all output stages are turned off, but the serial interface remains active. The output stages can be activated again by setting the bit SE high (when EN = high) or by switching EN back to high (when SE = high). Open-Load Detection When the open-load detection bit (OLD) is set to low, open-load detection is enabled. In this mode, a pull-down current for each low-side switch is turned on. When an open-load has been detected, the corresponding output bit (LSx or HSx) in the output data register is set to high. Once the open load is removed, the corresponding DO bit is cleared, indicating the end of the open-load event. Testing the open load of the H-bridge configuration is a two-step process. First, switch off all high-side (HSx/HSy) and low-side (LSx/LSy) drivers. The voltage at both clamps in this condition is pulled down. Next, with both low-side drivers off, switch on one high-side driver (HSx or HSy). Since the DC motor has a relatively low internal resistance, the voltage of the inactive high-side output should be at the same level as the activated high-side output. In the case of an open load, the inactive high-side output register reports a 0 if the active high-side output is 1. Conversely, if the load is connected, the inactive high-side output reports a 1. MP6526 Rev. 1.0 3/5/2019 Discharge Circuit Many typical applications use an inverse-polarity protection diode (see D1 in Figure 3). However, this method involves a certain risk. During inhibit mode, the IC consumes only an extremely low current (IVS), (i.e.: 20μA max). Any peaks on the supply voltage charge the blocking capacitor gradually. D1 prevents the capacitor from discharging via the power supply. Due to the extremely small quiescent current, discharging via the IC can also be neglected. This means that during long periods in inhibit mode, the IC's supply voltage could increase continuously until the maximum supply voltage limit of 40V is exceeded, damaging the IC. The device features a discharger circuit that prevents such unwanted effects. If VS exceeds a threshold value of approximately 37V, the blocking capacitor is discharged via an integrated resistor until VS falls below the threshold again. Figure 3: Functional Principle of the Discharger Circuit Over-Current Protection (OCP) The MP6526 has internal overload and short-circuit protection. The currents in both the high-side and low-side MOSFETs are measured. If the current exceeds the current limit, an internal timer is started. When a permanent over-current shutdown delay time programmed by the short-circuit timer bit (SCT) is reached, the short-circuit detection bit (SCD) is set, and the shorted output is disabled. By writing a high to the SRR bit in the input register, the SCD bit is reset, and the disabled outputs are enabled. www.MonolithicPower.com MPS Proprietary Information. Patent Protected.

All Rights Reserved. 15 MP6526 – HEX HALF-BRIDGE MOTOR DRIVER WITH SERIAL INPUT CONTROL Thermal Shutdown and Pre-Warning Thermal monitoring is also integrated into the MP6526. If the junction temperature rises above the thermal pre-warning threshold, the temperature pre-warning bit (TP) in the output register is set. When the temperature falls below the thermal pre-warning threshold, the bit TP is reset. The bit TP can be read without transferring a complete 16-bit data word. When CS = high to low, the state of TP appears at DO. After the microcontroller has read this information, CS is set high, and the data transfer is interrupted without affecting the state of the input and output registers. If the junction temperature rises above the thermal shutdown threshold, all switches turn off, and all bits in the output register are set high. Operation resumes immediately when the junction temperature has fallen below the thermal shutdown threshold and when a high has been written to the SRR bit in the input register. The thermal pre-warning threshold have hysteresis. and Power-Supply Fail If at any time the voltage on VS falls below the under-voltage lockout (UVLO) threshold voltage, an internal timer is started. The power supply fail bit (PSF) in the output register is set, and all outputs are disabled when a permanent UVLO delay time is reached. Operation resumes immediately when VS rises above the UVLO threshold. The PSF bit remains high until it is reset by the SRR bit in the input register. Fault Output The MP6526 includes an open-drain, active-low, fault indicator output (FAULT). A fault is indicated if the current limit is tripped or thermal shutdown is tripped. A fault on any channel causes FAULT to be pulled low. The FAULT value is maintained until the fault condition is removed and normal operation resumes. Do not apply more than 6V to FAULT. shutdown Note that bit0 to 15 = high indicates an over-temperature shutdown. MP6526 Rev. 1.0 3/5/2019 www.MonolithicPower.com MPS Proprietary Information.
