Monolithic Power Systems (MPS) MP6614 H-Bridge DC Motor Drivers
Monolithic Power Systems (MPS) MP6614 H-Bridge DC Motor Drivers are designed to drive reversible motors. These motor drivers integrate four N-channel power MOSFETs, and an internal charge pump generates the required gate driver voltages. The MP6614 motor drivers operate from a 5V to 35V input voltage range and deliver up to 2A continuous current (IOUT). These motor drivers provide a Pulse-Width Modulation (PWM) input interface compatible with industry-standard devices. The MP6614 motor drivers feature Over-Current Protection (OCP), Short-Circuit Protection (SCP), Under-Voltage Lockout (UVLO), and Over-Temperature Protection (OTP). These motor drivers are available in a SOIC-8EP package. Typical applications include solenoid drivers and brushed DC motor drivers.
