IS32LT3168 - SINGLE CHANNEL LINEAR LED DRIVER

Datasheet Summary

Description

The IS32LT3168 is a single channel linear programmable current regulator capable of up to 200mA.

Features

  • 124 steps Gamma-corrected Fade In and Fade Out algorithm. The output LED current gradually ramps up to the full source value after the ENB pin is asserted (pulled low) or the LED current gradually ramps down to zero when the ENB pin is deasserted (pulled high). The fade ramp can be interrupted mid-cycle before completion of the ramp cycle. The ENB pin can be connected to either an external logic level for direct control, or the Hall-effect switch output for contactless control. For 12V automotiv.

IS32LT3168 SINGLE CHANNEL LINEAR LED DRIVER WITH HALL-EFFECT SWITCH AND FADE IN/OUT FUNCTION June 2024 GENERAL DESCRIPTION The IS32LT3168 is a single channel linear programmable current regulator capable of up to 200mA. It operates as a standalone LED driver configurable with external resistors; a single external resistor programs the current level, while another resistor programs the Fade In/Out ramp rate for the channel. The IS32LT3168 also integrates a low-power and highsensitivity omnipolar Hall-effect sensor for contactless switching of the LEDs. The Hall-effect switch operates with either a north or a south magnetic pole.
