MP6515 35V, 2.8A, Phase/Enable Control H-Bridge Motor Driver in QFN 3x4 and TSSOP-EP Packages The Future of Analog IC Technology DESCRIPTION The MP6515 is an H-bridge motor driver. It operates from a supply voltage of up to 35V and delivers motor current up to 2.8A. Typically, the MP6515 is used to drive a DC brush motor. For the MP6515, control of the outputs is accomplished through the PHASE, ENBL, BRAKE, and BMODE pins. An internal current sensing circuit provides an output with voltage proportional to the load current. In addition, cycle-by-cycle current regulation/limiting is provided. These features do not require the use of a low-ohm shunt resistor. Internal safety features include over-current protection, input over-voltage protection, undervoltage lockout (UVLO), and thermal shutdown. The MP6515 is available in 16-pin 5.0mmx6.4mm TSSOP-EP and 3mmx4mm QFN package with exposed thermal pad.

It operates over a wide input voltage range of 5.4V to 35V. It is designed to drive bipolar stepper motors, DC brush motors, solenoids, or other loads.  Current Sensing  The current flowing in the two low-side MOSFETs is sensed with an internal current sensing circuit. A voltage that is proportional to the output current is sourced on VISEN. The VISEN output voltage scaling is set by a resistor connected between ISET and ground. For 1A of output current, 100µA of current is sourced into the resistor connected to ISET. For example, if a 10kΩ resistor is connected between ISET and ground, the output voltage on VISEN will be 1V/A of output current. Current is sensed when one of the low-side MOSFETs is turned on, including during slow decay (brake) mode. The load current applied to VISEN should be kept below 2mA, with no more than 500pF of capacitance. Current Limit/Regulation The current in the outputs is limited using constant off-time pulse width modulation (PWM) control circuitry. Operation is as follows: MP6515 Rev. 1.03 3/21/2019    Initially, a diagonal pair of MOSFETs turns on and drives current through the load. The current increases in the load, which is sensed by the internal current sense circuit. If the load current reaches the current trip threshold, the H-bridge switches to slow decay mode, with the two low-side MOSFETs turned on. After a fixed off-time (tITRIP), if the load current falls at least 20% below the current limit threshold, the FETs are reenabled and the cycle repeats. If the current is still higher than this level, the off time is extended until the current falls to 20% below the current limit threshold. The current limit threshold is reached when VISEN reaches 1.5V. For example, with a 10kΩ resistor from ISET to ground, the VISEN voltage is 1V/A of output current. Thererfore, when the current reaches 1.5A, VISET voltage reaches 1.5V, and a current trip occurs. During current regulation, nFAULT is not activated.

All Rights Reserved. 10 MP6515 – 35V, 2.8A, PHASE/ENABLE CONTROL, H-BRIDGE MOTOR DRIVER Blanking Time There is often a current spike during the turn-on, due to the body diode’s reverse-recovery current or the shunt capacitance of the load. This current spike requires filtering to prevent it from erroneously shutting down the high-side MOSFET. An internal fixed blanking time (tOCPD) blanks the output of the current sense comparator when the outputs are switched. This blanking time also sets the minimum on time for the high-side MOSFET. Input Logic For the MP6515, control of the outputs is accomplished through the PHASE, ENBL, BRAKE, and BMODE pins. See Table 1: Table 1: Output Control Pins ENBL PHASE BRAKE BMODE OUT1 OUT2 Function 1 0 X L H Reverse X 1 1 X H L Forward X 0 X 1 L L Brake (low) 0 0 X 1 H H Brake (high) 1 0 0 0 H* L* Sync fast decay X 0 1 0 X L* H* Sync fast decay * As the current through the H-bridge approaches zero, the outputs are tri-stated nSLEEP Operation Driving nSLEEP low puts the device into a low power sleep state. In this state, all internal circuits, including the gate drive charge pump, are disabled, and the H-bridge outputs are turned off. All inputs are ignored when nSLEEP is active low. When waking up from sleep mode, time (approximately 1ms) must pass before the outputs will operate. Fault The MP6515 provides an nFAULT pin, which is driven active low if any of the protection circuits are activated. These fault conditions include over-current, over-temperature, and overvoltage. nFAULT is not driven low when a current limit trip occurs. nFAULT is an opendrain output and requires an external pull-up resistor. When the fault condition is removed, nFAULT is pulled inactive high by the pull-up resistor. MP6515 Rev. 1.03 3/21/2019 Over-Current Protection The over-current protection circuit limits the current through each FET by reducing the gate drive to the FET. If the FET remains in the current limit condition for longer than the overcurrent deglitch time, all MOSFETs in the Hbridge will be disabled, and nFAULT will be driven low. The driver will remain disabled for tOCP, at which point it will be re-enabled automatically. Over-current conditions are sensed on both high and low side devices; i.e., a short to ground, supply, or across the motor winding will result in an over-current shutdown. Note that over-current protection does not use the current sense circuitry used for PWM current control, and it is independent of the ISET resistor value. Over-Voltage Protection If the input voltage applied to VIN is higher than the OVP threshold, the H-bridge output will be disabled, and nFAULT will be driven low. This protection is released when VIN drops to a safe level. Input UVLO Protection If at any time the voltage on VIN falls below the under-voltage lockout threshold, all circuitry in the device will be disabled and the internal logic will be reset. Operation will resume when VIN rises above the UVLO threshold. Thermal Shutdown If the die temperature exceeds safe limits, all MOSFETs in the H-bridge will be disabled, and nFAULT will be driven low. Once the die temperature has fallen to a safe level, operation will resume automatically. www.MonolithicPower.com MPS Proprietary Information. Patent Protected.
