STCS05

0.5 A max constant current LED driver

Features

Applications

input voltages

Description

The STCS05 is a BiCMOS constant current

source designed to provide a precise constant

current starting from a varying input voltage

source. The main target is to replace discrete

components solution for driving LEDs in low

voltage applications such as 5 V, 12 V or 24 V

giving benefits in terms of precision, integration

and reliability.

The current is set with external resistor up to 0.5

A with a ± 10 % precision; a dedicated pin allows

implementing PWM dimming.

An open-drain pin output provides information on

load disconnection condition.
