MP6612 – 45V, 5A, H-Bridge DC Motor Driver with Current Sense and IN1/IN2 Logic Inputs
The MP6612 from Monolithic Power Systems is a Half-Bridge DC Motor Driver that is used for driving reversible motors. It requires an input voltage of 4-45 V for operation and has an output current of up to 5 A. The motor driver consists of four N-channel power MOSFETs and an internal charge pump that generates the gate driver voltages. . It offers low quiescent current (IQ) in brake mode while two LS-FETs are on configurable current limit.
