Description

The STCS1A 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 1.5

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

implementing PWM dimming. An external

capacitor allows setting the slope for the current

rise from tens of microseconds to tens of

milliseconds allowing reduction of EMI.

An open-drain pin output provides information on

load disconnection condition.
