The TPS92611QDGNRQ1 is an AEC-Q100 qualified automotive-grade single-channel linear LED driver from Texas Instruments, housed in an 8-pin HVSSOP SMD package. It supports 4.5V to 40V wide input voltage range, delivers up to 350mA constant regulated output current, and integrates full fault diagnostic and protection features, making it a robust, high-reliability solution for automotive exterior and interior LED lighting systems that meet strict functional safety requirements.
Key Features and Highlights
● 40V Wide Transient Tolerance: Natively handles 40V automotive load-dump voltage transients without additional TVS protection components, simplifying vehicle power interface design.
● Precision Adjustable Constant Current: Output current can be easily programmed via an external low-side resistor, delivering ±5% maximum current accuracy across the full operating temperature range for consistent LED brightness.
● Built-In Full Fault Protection: Integrates LED open-circuit, short-circuit, and thermal shutdown fault detection, with dedicated fault flag output to notify the vehicle BCM of abnormal lighting status for functional safety compliance.
● Low Dropout Voltage Performance: Maximum 300mV dropout voltage at 350mA full load minimizes power dissipation and reduces thermal stress in compact automotive lighting enclosures.
Frequently Asked Questions (FAQ)
Q: Can this device directly drive multiple series-connected LEDs?
A: Yes, as long as the total LED forward voltage drop plus the device dropout voltage does not exceed the input supply voltage, it can drive multiple series LEDs with consistent constant current.
