Overview
NJU7381A LOW VOLTAGE OPERATION DUAL H BRIDGE DRIVER ■ GENERAL DESCRIPTION The NJU7381A is a dual H-bridge driver IC that features low voltage operation and low quiescent current.
The control method is 2 logic Inputs (2-IN) that includes standby mode.
The independent comparator circuit can be used for position sensing signal processing and the others.
Small package makes the NJU7381A suitable for small stepper motor and DC motor, such as portable applications.
