NCV7691: Current Controller for Automotive LED Lamps

Datasheet: Current Controller for Automotive LED Lamps

Product Overview

» Product Change Notification
The NCV7691 is a device which uses an external NPN bipolar device combined with feedback resistor(s) to regulate a current for use in driving LEDs. The target application for this device is automotive rear combination lamps. A single driver gives the user flexibility to add single channels to multichannel systems. A dedicated dimming feature is included via the PWM input pin. The individual driver is turned off when an open load or short circuit is detected. LED brightness levels are easily programmed using an external resistor in series with the bipolar transistor. The use of the resistor gives the user the flexibility to use the device over a wide range of currents. Multiple strings of LEDs can be operated with a single NCV7691 device. Set back power limit reduces the drive current during overvoltage conditions. The device is available in a SOIC−8 package.
