MP6612D

40V, 5A, H-Bridge DC Motor Driver with Current Sense and DIR/ENBL Control

Datasheet

Description

The MP6612D is an H-bridge motor driver used for driving reversible motors, which can drive a DC motor, the winding of a stepper motor, or other loads. The H-bridge consists of four N-channel power MOSFETs and an internal charge pump to generate the required gate-drive voltages.

For the MP6612, control of the outputs is accomplished through the IN1 and IN2 pins. For the MP6612D, control of the outputs is accomplished through the DIR and ENBL pins. Otherwise, both parts are identical.

The MP6612D operates across a 4V to 40V motor power supply voltage, which can supply an output current (I_OUT) 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 an output with a voltage proportional to the load current (I_LOAD). In addition, the MP6612D provides cycle-by-cycle current regulation and limiting. These features do not require the use of a low-ohmic shunt resistor.

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

The MP6612D requires a minimal number of readily available, standard external components, and is available in a TSSOP-20EP package with an exposed thermal pad.
