DESCRIPTION
The SP761X driver family provides a simple solution for a matched current source any color LED.
The current in the LEDs can be programmed by an external resistor. The Individual LED currents
are 200 x ISET, where ISET is the current through the external resistor connected to the CTRL
pin. The SP7611A is capable of driving four LEDs, while the SP7612 can drive three LEDs. The
SP7614 is designated to drive two high current LEDs. LED1 should always be connected to an
LED in order to have the other LEDs driven with a matched current to LED1.
The SP7612 and SP7614 have Enable pins. When these devices are disabled, the supply current
drops to 0.01碌A(chǔ) typical.
The SP7611A, SP7612 and SP7614 drivers are available in a small footprint 6-pin SC-70
package.
