IS32LT3175P Datasheet Single Channel Linear Led Driver

Manufacturer: Lumissil

Overview: IS32LT3175N/P SINGLE CHANNEL LINEAR LED DRIVER WITH FADE IN/OUT AND PWM DIMMING.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The IS32LT3175 is a single channel linear programmable current regulator capable of up to 150mA.

It integrates a debounce and latch circuit on the channel enable pin (EN) to facilitate the use of a low cost momentary contact switch.

The PWM pin can be interfaced to a logic level “courtesy light” signal to directly drive the LED channel.

Key Features

  • Operating voltage 5V to 42V.
  • Single channel current source - Programmable current via a single external resistor - Configurable from 20mA to 150mA.
  • Momentary contact button EN input - Input is debounced and latched - Higher priority than PWM input - Gamma corrected Fade In/Out algorithm - Pull down resistors set independent fade IN and OUT ramp time.
  • PWM input pin driven by external PWM source - PWM directly drives the current source - IS32LT3175P.
  • Positive polarity.
