Texas Instruments TPS92629Q1EVM

Overview

TPS92629Q1EVM from Texas Instruments is an evaluation module designed to validate the TPS92629-Q1 automotive-grade linear single-channel high-side LED driver. It supports 9–20 V input, delivers up to 250 mA output current per channel, enables analog and PWM dimming, and implements multi-fault reporting (short-to-battery, short-to-GND, open-circuit, thermal shutdown) for automotive exterior and interior lighting systems.

For engineers reviewing the TPS92629Q1EVM datasheet, TPS92629Q1EVM connector map, TPS92629Q1EVM test setup, or TPS92629Q1EVM BOM, this module provides a production-ready reference platform with AEC-Q200-compliant passives, validated thermal sharing resistors, jumper-configurable fault injection, and full diagnostic signal access via standardized headers.

Technical Context

The TPS92629Q1EVM directly interfaces with the TPS92629-Q1 IC (package: MSOP-8, part number TPS92629QDGNRQ1), replicating its automotive lighting control architecture. It implements real-time LED string monitoring using dedicated DIAGEN, FAULT, and Mult_FAULT outputs, and supports configurable open-fault masking during low-dropout operation.

Test configuration is enabled via six shunt jumpers (J1–J6) that emulate LED open/short conditions and select dimming modes. The board uses three 75 Ω, 1 W AEC-Q200 resistors (R3–R5) for external thermal sharing and a 1.8 Ω sensing resistor (Rsns) to set the 250 mA full-scale output current.

FAQ

What is the primary purpose of the TPS92629Q1EVM?

The TPS92629Q1EVM is an evaluation module built to accelerate design-in and validation of the TPS92629-Q1 automotive LED driver IC. It provides immediate access to all key signals-including EN/PWM, ADIM, DIAGEN, FAULT, and Mult_FAULT-enabling rapid testing of dimming behavior, fault detection accuracy, thermal sharing performance, and 3s1p LED string operation under real-world 9–20 V input conditions. The TPS92629Q1EVM includes documented test procedures and jumper-based fault simulation for production-grade verification.

Which LED driver IC does the TPS92629Q1EVM evaluate?

The TPS92629Q1EVM evaluates the TPS92629-Q1, a single-channel, high-side, linear automotive LED driver with integrated diagnostics. The EVM mounts the TPS92629QDGNRQ1 IC in an MSOP-8 package and replicates its complete functional interface-including thermal sharing control via external resistors, multi-level fault reporting, and analog/PWM dimming inputs. All schematics, layout, and BOM are publicly documented in the SLUUCQ6 user's guide.

How is output current set on the TPS92629Q1EVM?

The TPS92629Q1EVM sets full-scale output current to 250 mA using a 1.8 Ω sense resistor (Rsns). This value is derived from the TPS92629-Q1's internal 139 mV current-sense reference voltage (V_SENSE) and Ohm's Law: I_OUT = V_SENSE / R_sns = 0.139 V / 1.8 Ω ≈ 250 mA. Designers can adjust output current by replacing Rsns with a different resistance while maintaining stability and thermal limits within the TPS92629Q1EVM's PCB layout constraints.

What fault conditions can be simulated using jumpers on the TPS92629Q1EVM?

The TPS92629Q1EVM supports jumper-based fault simulation via J1–J4: J1 isolates the LED string to emulate open-circuit; J2 shorts one LED in the string; J3 shorts two LEDs; and J4 shorts the entire 3s1p LED string. These configurations allow direct validation of the TPS92629-Q1's short-to-GND, short-to-battery, and open-circuit detection logic-and corresponding FAULT/Mult_FAULT responses-without external test equipment. Each jumper position is documented in Table 2-2 of the SLUUCQ6 user's guide.

Does the TPS92629Q1EVM support both analog and PWM dimming?

Yes, the TPS92629Q1EVM supports both analog and PWM dimming through dedicated interfaces: ADIM accepts a 0–2.5 V analog control voltage, while EN/PWM accepts a 100 Hz–20 kHz PWM signal with active-high logic. Jumper J5 selects EN/PWM mode (shunted = internal pull-up to SUPPLY), and J6 selects ADIM mode (shunted = internal pull-up). Both paths are electrically isolated and validated per TPS92629-Q1 specifications, enabling independent or combined dimming strategies on the same TPS92629Q1EVM platform.
