Dual H-bridge Driver for Actuator

Download Datasheet

  • Description

    The NJU7385 is a dual H-bridge driver IC that has general versatility for a compact actuator.The Mode Select Function in the control part can select two types of control systems, “Two-input” and “Phase & Enable”. Input part has a Schmitt inverter circuit with a high resistance to noise.And it has a transition sequence which automatically transits to standby mode with no input signal. Output part has two circuit configurations of independent H-bridge. Protection circuit contains an under voltage lockout (UVLO) circuit and a thermal shutdown circuit and outputs alarm signal if an error is detected. Supply/interface voltage corresponds to the logic, 3.3V/5.0V.The NJU7385 is superior to performance compared to conventional products. It has the low current consumption and improved standby function (Auto/Manual). Especially, it is suitable for battery equipment. And it has versatility and a wide range of applications for various actuators, such as a compact step motor,DC motor, and solenoid.
