IS32LT3147
DESCRIPTION
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 thermal shutdown conditions. The FAULTB is a bi-directional open drain pin for reporting fault conditions and receiving system fault signal inputs. The FMODE pin configures the type of response to a fault signal, either “One Fail Other On” or “One Fail All Fail”.
The IS32LT3147 device is available in an e TSSOP-20 package with exposed pad for enhanced thermal dissipation.
