MP6551

14V, 5A, H-Bridge Motor Driver

Datasheet

Description

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_IN 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.

Advantages include:

Excellent solution for small, battery-powered products within the voltage and current range.
Low 30mΩ R_DS(ON) for high-side and low-side MOSFET supports low-voltage H-bridges.
Tiny QFN-14 (2.5mmx3mm) packages reduces PCB size.
