Dual H-bridge Driver for actuator
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.
