TLD1211SJ

Infineon LITIX™ Linear TLD1211SJ High Side Current Source 1 channel Typical 85mA load current, up to 2.5A load current using external transistors Datasheet Rev.1.1, 2021-11-22 Automotive LITIX™ Linear TLD1211SJ TLD1211SJ 1 Overview Features Adjustable Constant Output Current up to 85 mA LED Current of 2.5 A possible by using external Power Transistors Voltage Drop across Sense Resistor typ. 0.15 V Internal Bandgap Voltage Reference enables High Output Current accuracy EN Input for PWM brightness control Overvoltage Protection Temperature dependent Output Current Reduction Very Low Standby Current Maximum Operating Voltage 28 V Small SMD Package Green Product (RoHS compliant) AEC Qualified PG-DSO-8 Applications LED Controller for Automotive applications, Low- and High-Power LED Universal Constant Current Source Interior and Exterior Lighting Instrument backlighting Illumination Description The TLD1211SJ is an integrated adjustable constant current source realized in a bipolar IC technology. The IC is designed to supply LEDs under the severe conditions of automotive applications resulting in constant brightness and extended LED lifetime. The TLD1211SJ is capable to drive high current, high brightness LEDs up to 2.5 A by using additional external output stages as “booster“ transistors. For LED currents up to 85mA the IC can be used as a stand alone device and requires only one voltage sense resistor as an external component. Protection c...
