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
