NCV7693
NCV7693 is Automotive LED Controller manufactured by onsemi.
Controller for Automotive LED Lamps
The NCV7693 is a device which drives multiple external switching ponents for 3 independent functions. The average current in each LED string can be regulated with a proper choice of duty- cycle and battery voltage. The target application for this device is automotive rear bination lamps. Each individual driver has its own diagnostic to detect open load, short circuit to ground or to battery.
LED average brightness levels are easily programmed using appropriate duty cycle control and external resistors in series with the switching transistors.
Multiple strings of LEDs can be operated with a single NCV7693 device. The device is available in a...
