The MP6550 is an H-bridge motor driver. The H-bridge consists of four N-channel power MOSFETs and an internal charge pump to generate gate-drive voltages. The MP6550 is typically used to drive a DC brush motor.
The MP6550 operates on a motor power supply voltage from 1.8V to 22V, which can supply an output current of up to 2A according to the logic control.
The MP6550 has a PWM input interface, which is compatible with industry-standard devices. Very low standby circuit current can be achieved when the device is disabled.
An internal current-sensing circuit provides an output with a voltage proportional to the load current. Cycle-by-cycle current regulation and limiting is also provided. These features do not require the use of a low-value shunt resistor.
There are internal shutdown functions for over-current protection, short-circuit protection, under-voltage lockout, and over-temperature protection.
The MP6550 requires a minimal number of readily available, standard external components, and is available in a QFN-12 (2mmx2mm) package.
