NTE1478 Integrated Circuit 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: D Internal Output Power Transistor: 5A Load Current Capability D Programmable Switch: Manual Operation Can be Obtained D Pause Switch: Switching Pause (Switch ON), Plunger Does Not Operate Even if the Rotary Detective Signal Stops. D Internal Load Dump Protector (Excessive Supply Voltage) D Response Time and Driving Time are Variable with External Capacitors D Input Sensitivity Voltage: 2VP-P Min D Operating Supply Voltage Range: VCC = 9V to 18V Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Load Current, IOUT . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5A Power Dissipation (TC = +25C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12.5W Peak Supply Voltage (1200 ms), VCCsurge . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40V Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -30 to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +150C Electrical Characteristics: (VCC = 13.2V, RL = 3.3, TA = +25C, unless otherwise specified)
