MP6551

14V, 5A, H-Bridge

Motor Driver

DESCRIPTION

FEATURES

The MP6551 is an H-bridge motor driver. Its

2.5V to 14V input voltage (V_IN) 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 (I_OUT) across its entire V_INrange.
