The EV6550-G-00A is an evaluation board for the MP6550, an H-bridge motor driver. It operates from a supply voltage of up to 22V and can deliver motor current up to 2A.
The MP6550 has a PWM interface, which is compatible with industry-standard devices. Very low standby circuit current can be achieved when disabled the device. The MP6550 is available in a QFN2X2-12 package, it is typically used to drive a DC brushed motor.
