STMicroelectronics, STCS1APHR
- RS Stock No. 188-9213
- Mfr. Part No. STCS1APHR
- Manufacturer STMicroelectronics
The STCS1A 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.
