Overview
The STCS1 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 5 V, 12 V, 24 V component solution for driving LEDs in low voltage applications.
Applications
- Constant current supply for LEDs with varying input voltage
- Low-voltage lighting
- Small appliance LED lighting
- Automotive LED lighting
Key features
- Input voltage up to 40V
- Voltage overhead less than 0.5V
- Output current up to 1.5A
- PWM dimming pin
- Shutdown pin
- LED open-circuit diagnostic function
- Available in DFN8 (3x3mm) and PowerSO-8 packages
- Current set via external resistor, up to 1.5A, ±10% accuracy
- Current consumption less than 1μA in shutdown mode
- PWM dimming input frequency range from a few Hz to 50kHz
- LED string open-circuit or fault detection with status output via DISC pin
