MPQ6612A-D-AEC1

40V, 5A, H-Bridge DC Motor Driver with Current Sense and ENBL/DIR Inputs, AEC-Q100 Qualified

Datasheet

Description

The MPQ6612A-D-AEC1 is an H-bridge motor driver used for driving reversible motors, and it can drive one DC motor, one winding of a stepper motor, or other loads. The H-bridge consists of four N-channel power MOSFETs and an internal charge pump that generates the required gate-drive voltages.

For the MPQ6612A-D-AEC1, control of the outputs is accomplished through the DIR and ENBL pins. For the MPQ6612A-AEC1, control of the outputs is accomplished through the IN1 and IN2 pins. Otherwise, both parts are identical.

The MPQ6612A-D-AEC1 operates on a motor power supply voltage from 4V to 40V, which can supply an output current (I_OUT) of up to 5A according to the logic control. A very low standby quiescent current (I_Q) can be achieved when the device is disabled.

An internal current-sense (CS) circuit provides a voltage proportional to I_OUT. In addition, it integrates cycle-by-cycle current regulation and limiting. These features do not require the use of a low-ohmic shunt resistor.

There are internal shutdown functions for over-current protection (OCP), over-voltage protection (OVP), under-voltage lockout (UVLO), and over-temperature protection (OTP).

The MPQ6612A-D-AEC1 requires a minimal number of readily available, standard external components. It is available in a QFN-18 (3mmx4mm) package and is AEC-Q100 qualified.
