IS32LT3175N - SINGLE CHANNEL LINEAR LED DRIVER

Datasheet Summary

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.

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.

IS32LT3175N/P SINGLE CHANNEL LINEAR LED DRIVER WITH FADE IN/OUT AND PWM DIMMING 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. The IS32LT3175P accepts a positive polarity PWM signal while the IS32LT3175N accepts a negative polarity PWM signal. The device operates as a stand-alone LED driver configurable with external resistors; no microcontroller is required.
