IS32LT3140A - SINGLE CHANNEL 450mA LED DRIVER

Lumissil

Datasheet Details

The IS32LT3140A is an automotive-grade high-side programmable current regulator consisting of a single output channel capable of 450mA.

an EN pin to enable or shutdown the device. It supports either PWM dimming via a PWM pin or power supply modulation (PSM). A resistor divider circuit can be used on the UV pin to set an external VCC under-voltage lockout threshold for LED string open and single LED short fault detection. In addition, the IS32LT3140A integrates fault protection for a single LED short, LED string open/short, output overcurrent (not reported), and over-temperature condition for robust operation. Detection of these.
