GENERAL DESCRIPTION
The SP712X driver’s family provides a simple solution for a matched current source for any
color common cathode LED configuration. The common cathode connection allows the user to
increase the LED power dissipation by having the cathodes heat-sinked to the ground plane of
the circuit board. The SP7120 may drive two LEDs or one LED at twice the current with two
channels connected in parallel. The SP7122 can drive three LEDs or one LED at three times
the current. The factory preset current values are 15mA (version A), 20mA (version B), or 25mA
(version C) per channel. In shutdown mode (EN pin is LOW), the supply current drops to 40nA
typical. The SP712x drivers are available in a small footprint 6-pin SOT23-6 package.
