MP6551 Datasheet | Monolithic Power Systems

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 3cell 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.
