  • 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.

    Key Features

    • 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
