STMICROELECTRONICSSTCS2SPRIC: driver
The STCS2 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 2 A with a ± 10 % precision a dedicated pin allows implementing PWM dimming. An open-drain pin output provides information on load disconnection condition. LED disconnection diagnostic Up to 40 V input voltage Up to 2 A output current Less than 0.5 V voltage overhead Shutdown pin PWM dimming pin Applications LED constant current supplying for varying input voltages Low voltage lighting Small appliances LED lighting Car LED lights
