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.
Excellent solution for small, battery-powered products within the voltage and current range.
Low 30mΩ RDS(ON) for high-side and low-side MOSFET supports low-voltage H-bridges.
The EV6551-QB-00A is an evaluation board designed to demonstrate the capabilities of the MP6551, an H-bridge motor driver.
The MP6551 provides up to 5A of output current (IOUT) across a wide 2.5V to 14V input voltage (VIN) range. Its input control signals are applied via a connector on the evaluation board (EN1, EN2, IN1, and IN2).
