NTE Electronics 

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.

Features:

D Two Separate Full Bridge Drivers (Only one circuit can be switched by the Select (SE) Input).

D Wide Operating Voltage Range: VCC = 4V to 16V

D TTL, PMOS, CMOS Outputs, Capable of Direct Drive

D Low Output Saturation Voltage

D Built−in Clamp Diode

D High Output Drive Current: IOmax = ±2A

D Braking Mode Input

D Internal Thermal Shutdown Protection

Applications:

D Audio Tape Deck Player

D Radio/Cassette Player

D Video Cassette Recorder

D Home Equipment Use
