DESCRIPTION

The MP6551 is an H-bridge motor driver. Its

2.5V to 14V input voltage (VIN) range allows the

device to operate from a variety of battery

power sources, including single-cell lithium-ion

batteries, dual-cell lithium-ion batteries, and 3-

cell to 6-cell alkaline batteries. Its low on

resistance enables it to achieve up to 5A of

output current (IOUT) across its entire VIN range.

The MP6551 can drive a brushed DC motor in

bidirectional applications or two DC motors in

unidirectional, speed-controlled applications.

Full protection features include over-current

protection (OCP), under-voltage lockout

(UVLO) protection, and thermal shutdown.

The MP6551 is available in a QFN-14

(2.5mmx3mm) package.
