IS32LT3147 - Lumissil

IS32LT3147 6-CHANNEL LINEAR LED DRIVER

The IS32LT3147 is a six-channel linear LED driver supporting a thermal shunt resistor for power dissipation to minimize the device thermal stress. Each channel has its own individual PWM control input. For added system reliability, the IS32LT3147 integrates fault detection circuitry for LED open/short circuit, single LED short circuit, thermal roll-off and t.

Features
