MP6612DGF Datasheet | Monolithic Power Systems

DESCRIPTION The MP6612 and MP6612D are H-bridge motor drivers used for driving reversible motors, which can drive a DC motor, or 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 acplished through the IN1 and IN2 pins. For the MP6612D, control of the outputs is acplished through the DIR and ENBL pins. Otherwise, both parts are identical. References to the MP6612 in this document also apply to the MP6612D unless otherwise noted. The MP6612 operates on a motor power-supply voltage from 4V to 40V, which can supply an output current (IOUT) up to 5A according to the logic control. Very low standby quiescent current (IQ) can be achieved when disable the device. An internal current-sense (CS) circuit provides an output with a voltage proportional to the load current (ILOAD). In addition, the MP6612 provides cycle-by-cycle current regulation and limiting. These features do not require the use of a lowohmic 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 MP6612 and MP6612D require a minimal number of readily available, standard external ponents, and are available in TSSOP-20 with an exposed thermal pad package.
