Description

The SP761X driver family provides a simple solution for a matched current source for any color LED. The current in the LEDs can be programmed by an external resistor. The SP7611A is capable of driving four LEDs, while the SP7612A can drive three LEDs. The SP7614A is designed to drive two high current LEDs. LED1 should always be connected to an LED and never left open in order to have the other LEDs driven with a matched current to LED1. The SP7612A and SP7614A feature Enable pins for flexible on/off control and PWM dimming. SP7612A/4A has extremely low (0.01uA typical) shutdown current, prolonging the battery life and giving the longest standby period possible in today's modern design. SP761X driver family is available in a small footprint 6-pin SC-70 package as well as the 6-pin 2x2 TDFN.
