The MP6522 is an H-bridge motor driver that operates from a supply voltage of up to 35V and delivers a peak motor current of up to 3.2A. The MP6522 is typically used to drive DC brush motors.
An internal current-sensing circuit provides an output with a voltage proportional to the load current. Additionally, cycle-by-cycle current regulation and limiting is provided. These features do not require the use of a low-ohm shunt resistor.
Full protection features include over-current protection (OCP), input over-voltage protection (OVP), under-voltage lockout (UVLO), and thermal shutdown.
The MP6522 is available in a 24-pin QFN (5mmx5mm) package with an exposed thermal pad.

The EV6522-U-00A is an evaluation board for the MP6522, an H-Bridge motor driver.
It operates from a supply voltage of up to 35V and can deliver 2A continuous current, 3.2A peak current. The input control signals for the MP6522 can be set by SW1 or applied through the connector CN1 on the board.
