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.

Overview

IS32LT3140A SINGLE CHANNEL 450mA LED DRIVER WITH THERMAL SHUNT RESISTOR AND SINGLE LED SHORT DETECTION May 2024.

Key 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.
