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.
