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.
A single external resisto...
