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.
