MAX6978 5.5V Constant-Current LED Driver

MAX6978 Description

19-3578; Rev 1; 3/05 8-Port, 5.5V Constant-Current LED Driver with LED Fault Detection and Watchdog General .
The MAX6978 serial-interfaced LED driver provides eight open-drain, constant-current sinking LED driver outputs rated at 5.

MAX6978 Features

* 25Mb Industry-Standard 4-Wire Serial Interface at 5V MAX6978 Ordering Information PART MAX6978AUE MAX6978APE MAX6978AEE TEMP RANGE -40°C to +125°C -40°C to +125°C -40°C to +125°C PIN-PACKAGE 16 TSSOP-EP

MAX6978 Applications

* which blanks the display if the serial interface fails. If the serial interface becomes inactive for more than 1s, all driver output latches are automatically cleared. This turns off all LEDs connected to the outputs. The shift register data is not disturbed. The outputs remain off until the driver
