NTE1628
Integrated Circuit
Bi−Directional Motor Driver
Description:
The NTE1628 is a Bi−Directional Motor Driver in a 9−lead SIP type package consisting of a full bridge
power driver and is designed for DC motor control.
Features:
D Wide Operating Voltage Range (VCC = 4V to 16V)
D Direct Drive Capabilty by TTL, PMOS, and CMOS IC Outputs
D Low Output Saturation Voltage (Large Voltage Across Motor)
D Built−In Clamp Diode
D Large Output Current Drive (IO(max) = ±1.2A)
D Braking Mode Input
Application:
Commercial Audio Equipment such as Tape Recorder, Radio Cassette Recorder, and VCR
Function:
The NTE1628, full bridge motor driver, has the logic circuitry and non−darlington power drivers for
bidirectional control of DC motors operating at currents up to 1.2A. A braking mode is acheived by
switching both inputs high for ease of motor control. Both of the separated power supplies for the logic
circuitry and the drivers are usuable for motor speed control.
