Description
The STCS1 is a Bi CMOS constant current source designed to provide a precise constant current starting from a varying input voltage source. The main target is to replace discrete ponents 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 open-drain pin output provides information on load disconnection condition.
