MPQ6612A - H-Bridge DC Motor Driver

General Description

The MPQ6612A and MPQ6612A-D are H-bridge motor drivers used for driving reversible motors, which can drive one DC motor, one winding of a stepper motor, or other loads.

The H-bridge consists of four N-channel power MOSFET, and an internal charge pump that generates the required gate-drive voltages.

Key Features

  • do not require the use of a low-ohmic shunt resistor. There are internal shutdown functions for overcurrent protection (OCP), over-voltage protection (OVP), under-voltage lockout (UVLO) and over-temperature protection (OTP). The MPQ6612A and MPQ6612A-D require a minimal number of readily available, standard external components. Both are available in a QFN-18 (3mmx4mm) package, and are AECQ100 qualified.

MPQ6612A/MPQ6612A-D 40V, 5A, H-Bridge DC Motor Driver with Current Sense, AEC-Q100 DESCRIPTION The MPQ6612A and MPQ6612A-D are H-bridge motor drivers used for driving reversible motors, which can drive one DC motor, one winding of a stepper motor, or other loads. The H-bridge consists of four N-channel power MOSFET, and an internal charge pump that generates the required gate-drive voltages. For the MPQ6612A, control of the outputs is accomplished through the IN1 and IN2 pins. For the MPQ6612A-D, control of the outputs is accomplished through the DIR and ENBL pins. Otherwise, both parts are identical. References to the MPQ6612A in this document also apply to the MPQ6612A-D unless otherwise noted.
