Solenoid Driver & Signal Sensing Circuit
Description:
The NTE1478 is an integrated circuit in a 10–Lead SIP type package that detects the stopping of a
rotary signal and drives a plunger. It is designed for use in auto–reverse and auto–eject car stereo
applications and can be used as a solenoid driver in many other control circuits.
Features:
Internal Output Power Transistor: 5A Load Current Capability
Programmable Switch: Manual Operation Can be Obtained
Pause Switch: Switching Pause (Switch ON), Plunger Does Not Operate Even if the Rotary
Detective Signal Stops.
Internal Load Dump Protector (Excessive Supply Voltage)
Response Time and Driving Time are Variable with External Capacitors
