MP6612: H-Bridge DC Motor Driver With Current Sense
Suitable Driver for Reversible Motors
With the MP6612 MPS have introduced a H-bridge motor driver which can drive reversible motors, DC motors, one stepper motor winding or other inductive loads. The H-bridge consists of four N-channel power MOSFETs and an internal charge pump that generates the gate driver voltages. The outputs are controlled via the IN1 and IN2 pins.
4V to 45V Motor Power Supply Voltage
The device operates from a 4V to 45V motor power supply voltage, which can supply up to 5A of output current (IOUT) according to the logic control. A low standby circuit current can be achieved while the device is disabled. An internal current-sense circuit provides an output voltage (VOUT) that is proportional to the load current. Cycle-by-cycle current regulation/limiting is also provided. This feature do not require the use of a low-ohmic shunt resistor.
Internal shutdown functions include over-current protection (OCP), over-voltage protection (OVP), under-voltage lockout (UVLO) protection and over-temperature protection (OTP). The MP6612 requires a minimal number of standard external components and is available in a TSSOP-20 package with an exposed thermal pad.
