PRODUCTION DATA
The TPS92629-Q1 is a single-channel, high-side linear LED driver supporting external thermal sharing resistor to achieve the controllable junction temperature rising. The device can be directly powered by automotive battery and output full load up to 250 mA current to LED with limited power dissipation on the device. The channel current output can be set by external R(SNSx) resistors. Current flows from the supply through the R(SNSx) resistor into the integrated current regulation circuit and to the LEDs through OUTx pin and RESx pin. TPS92629-Q1 device supports both supply control and PWM control to turn LED ON and OFF. The LED brightness is also adjustable by input PWM duty cycle applied on ADIM pin to achieve analog dimming control. The output current slew rate is optimized for improved EMC performance in analog dimming mode. The TPS92629-Q1 provides full diagnostics to keep the system operating reliably including LED open/short-to-ground/short-to-battery circuit detection, supply POR and thermal shutdown protection. The LED fault detection is optimized to support big output capacitor in analog dimming mode within wide current range for better stability and noise immunity in the off board long wire driving applicaton. TPS92629-Q1 device is in a HVSSOP package with total 8 leads.
