IS32LT3140A - SINGLE CHANNEL 450mA LED DRIVER

Datasheet Summary

Description

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

An external resistor sets the current level for the single-channel current source.

Features

  • 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.

IS32LT3140A SINGLE CHANNEL 450mA LED DRIVER WITH THERMAL SHUNT RESISTOR AND SINGLE LED SHORT DETECTION May 2024 GENERAL DESCRIPTION The IS32LT3140A is an automotive-grade high-side programmable current regulator consisting of a single output channel capable of 450mA. An external resistor sets the current level for the single-channel current source. An optional thermal shunt resistor can be used to significantly optimize IC power dissipation. It features 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.
