LED Driver Provides Fault Output

For automotive tail-lamp, side-lamp, and turn-signal applications, the MAX16839 high-brightness LED driver delivers up to 100 mA and minimizes external component count by integrating a pass element and fault detection. In addition, it allows interoperability of multiple drivers in multi-string applications. An onboard pass transistor and a wide input-voltage range enable the device to maintain a constant LED current even when the battery voltage changes. It sustains load-dump events up to 45V and keeps the LED current constant during them. Prices start at $0.73 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
