com DUAL H BRIDGE DRIVER WITH COMPARATOR ■ Package Outline ■ GENERAL DESCRIPTION The NJU7382 is a dual H-bridge driver IC especially developed low voltage small stepper motor applications.
It consists of a pair of low consumption CMOS H-bridge drivers protected by thermal shutdown circuit.
It is also including a general-purpose comparator suited for detection from photo reflector as rotor position sensor or current limitation.
NJU7382PC1 The NJU7382 adopt a very small FFP package, it is suitable for mobile or portable applications using micro stepper motors.
■ FEATURES •Operating Voltage 2.
