STCS1PHR

Overview

The STCS1PHR is a BiCMOS constant current source designed for low-voltage LED applications. It provides a precise constant current up to 1.5 A with ±10% precision, set via an external resistor. The device supports PWM dimming through a dedicated pin and includes an open-drain output for load disconnection diagnostics. It operates with an input voltage up to 40 V and maintains a voltage overhead of less than 0.5 V.

Feature Summary

BiCMOS technology for high precision and reliability in varying input voltage sources
Integrated PWM dimming capability via a dedicated control pin
Diagnostic feature providing open-drain output for LED disconnection detection

Applications

LED lighting drivers in 5 V, 12 V, or 24 V systems
Replacement for discrete component solutions in low voltage LED driving
Applications requiring precise constant current regulation and load monitoring

Procurement Notes

Verify the specific suffix 'PHR' against the official STMicroelectronics datasheet to confirm package type and tape/reel specifications. Ensure the selected variant matches the required thermal and mechanical constraints for the target PCB layout. Cross-reference the ordering code with the manufacturer's latest documentation to avoid discrepancies in package marking or environmental compliance status.

Selection Notes

Select this component when replacing discrete LED driver circuits with a single-chip solution offering higher integration and reliability. Consider the 1.5 A maximum current limit and the requirement for an external setting resistor. Evaluate the need for PWM dimming and disconnection diagnostic features as primary selection criteria over standard constant current sources.

Part Context

The STCS1 series comprises BiCMOS constant current sources intended for low-voltage LED applications. These devices aim to replace discrete solutions by providing integrated precision, improved reliability, and simplified design. The STCS1PHR is a specific variant within this family, optimized for driving LEDs from varying input voltages such as 5 V, 12 V, or 24 V.
