Dual H-bridge Driver for actuator

GENERAL 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.
