Texas Instruments TPS92622Q1EVM

Overview

TPS92622Q1EVM from Texas Instruments is an evaluation module designed to validate the TPS92622-Q1 two-channel automotive high-side LED driver, supporting 9–20 V input, 130 mA per channel output, and 2-series-1-parallel LED string configuration for rear lamps, CHMSL, and interior lighting.

For engineers reviewing the TPS92622Q1EVM datasheet, TPS92622Q1EVM test setup, TPS92622Q1EVM connector map, or TPS92622Q1EVM BOM, this EVM enables rapid functional validation of LED open/short diagnostics, thermal sharing via external resistor, and PWM dimming control in AEC-Q200-compliant automotive lighting designs.

Technical Context

The TPS92622Q1EVM implements a linear two-channel high-side LED driver architecture with integrated fault detection logic, supporting independent PWM1/PWM2 inputs and FAULT status reporting via dedicated test points. It uses external current-sense resistors (1.15 Ω) and thermal-sharing resistors (100 Ω) to configure per-channel current and thermal derating behavior.

Board-level features include jumper-configurable LED open/short test modes (J3–J6), shunt-enabled PWM dimming (J1/J2), and discrete connectors for Vbat1, GND1, TP1 (LED ground), TP2 (input voltage monitor), and TP3 (FAULT output), enabling flexible bench characterization without soldering.

FAQ

What is the primary function of the TPS92622Q1EVM?

The TPS92622Q1EVM is an evaluation module used to characterize and validate the TPS92622-Q1 two-channel automotive high-side LED driver. It provides accessible test points, configurable jumpers, and a complete BOM to verify LED open/short diagnostics, thermal sharing, PWM dimming, and current regulation performance under real-world 9–20 V input conditions before integration into final lighting systems.

Does the TPS92622Q1EVM support both channels independently?

Yes, the TPS92622Q1EVM supports fully independent operation of both channels: each has its own PWM input (J1/J2 configurable), LED string connection (TP1 ground path), current-sense resistor (R6/R7), and open/short test jumpers (J3–J6). This allows simultaneous or isolated testing of CH1 and CH2 functionality, including separate fault reporting via the shared FAULT pin (TP3).

How is LED current set on the TPS92622Q1EVM?

LED current on the TPS92622Q1EVM is set by the 1.15 Ω current-sense resistors (R6 and R7) placed in series with each channel's LED return path. With the TPS92622-Q1's internal 130 mV reference, this yields 130 mA per channel (I_OUT = 0.13 V / 1.15 Ω). The value can be adjusted by replacing R6/R7 with different resistances to scale output current proportionally.

Can the TPS92622Q1EVM be used for AEC-Q200 compliance testing?

Yes - the TPS92622Q1EVM incorporates AEC-Q200-qualified passive components including capacitors (C1–C7), resistors (R1–R13), and diodes (D1), and is built around the AEC-Q200-qualified TPS92622QPWPRQ1 IC. While the EVM itself is not certified, its BOM and layout support stress testing and environmental validation aligned with AEC-Q200 requirements for automotive lighting subsystems.

What diagnostic features does the TPS92622Q1EVM demonstrate?

The TPS92622Q1EVM demonstrates LED open and short detection with auto-recovery, open-fault masking during dropout mode, and FAULT status output (TP3). These are validated using jumpers J3–J6 to simulate open/short conditions and observing FAULT pin behavior across input voltage transitions and PWM modulation cycles - directly reflecting the TPS92622-Q1's integrated diagnostic architecture.
