IS32LT3175P - SINGLE CHANNEL LINEAR LED DRIVER

Download the IS32LT3175P datasheet PDF. This datasheet also covers the IS32LT3175N variant, as both devices belong to the same single channel linear led driver family and are provided as variant models within a single manufacturer datasheet.

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.

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.

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.
