DESCRIPTION

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.
