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.
