            TSCR4 LED Driver ICs
                    Taiwan Semi's Driver ICs are direct socket replacement for bipolar components; delivering improved performance at comparable cost
    

Image of Taiwan Semi’s TSCR4 LED Driver ICs The Taiwan Semiconductor TSCR4 family of linear CMOS LED driver ICs offers a drop-in replacement for legacy bipolar drivers with much improved performance . These constant current drivers provide stable LED current over a wide range of conditions including source voltage variations and changes in load or temperature variations. Compared to legacy bipolar LED drivers, the TSCR4 family offers higher current setpoint accuracy and stability, lower quiescent current, tighter output compliance voltage, and improved temperature coefficient. These ICs enable upgrades of existing designs for higher performance with no re-design effort required.

Features

Higher accuracy of output current improves manufacturing yields in mass production
Lower quiescent current (e.g., 300 mA. vs 1 A at 24 V_DC) lowers power dissipation and reduces battery standby and operating power consumption
More precise output voltage drop: CMOS control of voltage drop enables operation closer to the rail
Higher stability of output current delivers consistent brightness control and extends LED life
Better temperature coefficient (-0.07%/°C) controls output current with temperature increases to eliminate the risk of thermal runaway
AEC-Q100 parts available, ideal for many basic automotive lighting applications
PWM dimming: up to 10 KHz digital input for 0 to 100% dimming (TSCR421CX6/H)
Supply voltage up to 40 V, supports large LED arrays
Easy parallel driver structure

Applications

Automobile, truck and bus interior, and exterior lighting
Architectural lighting
Signage, advertising, and decorative lighting

Refrigerator and freezer case lighting
Kiosk and vending machine lighting
Emergency lighting (exit signs, stairsteps, and emergency pathway lighting)
