NTE1892 & NTE1892A
Integrated Circuit
Dual Bi−Directional Motor Driver
with Brake Function and Thermal Shutdown
Description:
The NTE1892 and NTE1892A are bi−directional motor drivers in a 12−Lead SIP type package and
consists of two full bridge drivers designed for use in a two DC motor control circuit.
