Power logic: single-chip solution control
High-brightness drivers
2009
www.st.com/powerlogic
driver (power logic) family from STMicroelectronics fully integrates functions required drive highbrightness LEDs. These devices allow constant-current control single-chip solution. external parts reduced only resistor which sets preferred maximum current outputs. innovative feature this family clock data resynchronization; this occurs when devices connected cascade. Devices also come with additional features such high current, high precision, thermal shutdown, error detection auto power-saving functionalities.

Applications
Thermal protection reduces risk damaging device when exceeds prolongs device lifespan Embedded error detection detects status remotely field system could activate service crew event failure Embedded power-saving circuitry drives device with quiescent current when outputs active achieving power saving especially beneficial battery/solar-operated applications
Full-color monochrome driving: electronic matrices high-resolution giant video displays Consumer electronics: 7-segment digits discrete driving Industrial: gaming machines white goods General lighting: power-LED driving special architectural lighting Display backlighting Traffic displays, roadwork signage batteryoperated solar-powered electronic signs
Auto power saving
product specially developed reduce total power consumed drivers that actively driving output real-time. This auto power shutdown power-on feature allows device save power without external intervention, making ideal solution support worldwide energy-saving programs which encourage power efficiency lighting applications.

Output error detection
device features built-in error detection short-to-ground, short-to-supply open-line faults. error detection mode remotely controlled using specific digital keys through device's port. Fault data shifted device same with additional pin. This reduces system downtime alerting maintenance crews event faulty LED.
