The TPS92630QPWPRQ1 is a Texas Instruments AEC-Q100 Grade 1 qualified, three-channel linear LED driver with analog and PWM dimming control, packaged in a thermally enhanced 16-pin HTSSOP (PWP) and supplied on tape-and-reel for automated assembly. Operating from a wide 5 V to 40 V input, it delivers up to 150 mA per channel (450 mA with paralleled outputs) with ±1.5% per-channel current accuracy, and integrates comprehensive diagnostics—including open, short, and single-LED-short detection with programmable deglitch timers, fault bus reporting for up to 15 devices, and a programmable thermal-foldback monitor—making it a robust, single-chip solution for medium-power automotive and industrial LED lighting.
Key Features & Benefits
● Three Independently Controlled Channels: Each channel supports 1-to-3 LEDs with independent PWM dimming and adjustable constant current set by a single reference resistor.
● ±1.5% Current Accuracy: Tight channel-to-channel and device-to-device matching ensures uniform brightness across multiple lamp assemblies.
● Parallel Outputs to 450 mA: Channels and multiple ICs can be paralleled to drive higher-current single strings without external ballast circuitry.
● Programmable Thermal Foldback: An external resistor on the TEMP pin sets a derating threshold that linearly reduces LED current when junction temperature rises; grounding TEMP disables the feature.
● Low Dropout Voltage: Only 0.9 V maximum at the full 150 mA per channel, minimizing wasted power and heat in the linear pass elements.
● Common-Cathode String Topology: High-side drive requires only a single return wire instead of one per string, cutting harness weight and connector pin count.
● Wide 5 V–40 V Input with dV/dt Tolerance: Handles slow supply transients up to 0.5 V/min and automotive load-dump conditions without external clamping.
Frequently Asked Questions
Q: How is the output current set?
A: A single resistor from the REF pin to GND programs the constant current; each channel then mirrors this value with ±1.5% accuracy.
Q: What is the maximum number of LEDs per channel?
A: Up to three LEDs per channel at full current (limited by the 40 V input and 0.9 V dropout), or more at reduced current within the package power dissipation.
