Fonctionnalités et applications

The STCS1APUR 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.


  • Up to 40 V input voltage
  • Less than 0.5 V voltage overhead
  • Up to 1.5 A output current
  • PWM dimming pin
  • Shutdown pin
  • LED disconnection diagnostic
  • Slope control with external cap


  • LED constant current supplying for varying input voltages
  • Low voltage lighting
  • Small appliances LED lighting
  • Car LED lights
