Product details
Overview
TPS658629IZWSRQ1 from Texas Instruments is an automotive-grade advanced power management unit (PMU) integrating three programmable step-down converters (SM0–SM2), eleven LDOs, dual RGB LED drivers, a constant-current WLED driver, and an 11-channel ADC. It supports I²C host interface, hardware on/off control, AUTOBOOT, and operates from –40°C to 85°C ambient. Used in portable navigation devices and media players for centralized power sequencing and display support.
For engineers reviewing the TPS658629IZWSRQ1 datasheet, TPS658629IZWSRQ1 pinout, TPS658629IZWSRQ1 application, or TPS658629IZWSRQ1 equivalent, key selection considerations include its AEC-Q100 Grade 3 qualification, 169-pin nFBGA (ZWS) package, integrated USB current limiting, over-voltage protection up to 26.5 V, and software-controlled forced PWM mode for dynamic efficiency optimization.
Technical Context
The TPS658629IZWSRQ1 implements a multi-rail PMU architecture with independent digital control of each DC/DC converter and LDO via I²C registers. Its system management includes maskable interrupts, external ADC triggering, and hardware reboot logic - enabling coordinated power-up/down sequencing across complex SoC platforms.
Display support is implemented through four programmable PWM outputs driving dual RGB channels and a dedicated 26.5 V, 25 mA constant-current WLED driver with brightness control. All supply outputs feature Power Good monitoring and automatic power-saving modes triggered by load conditions and register settings.

Equivalent & Alternatives
The following parts are listed as comparable options for similar power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65910A3RSLR | 10-channel LDO, 3 buck converters, no WLED driver; smaller 144-ball nFBGA; lower max input (5.5 V) | Targeted at lower-power applications without display backlight needs; lacks 26.5 V WLED capability and RGB drivers | Select when display functionality is absent and input voltage stays below 5.5 V - reduces cost and footprint but sacrifices display integration. |
| MAX20029ATG/V+T | 3 buck, 5 LDO, integrated watchdog and CAN transceiver; 40-pin TQFN; supports CAN FD; higher ESD rating (H2B) | Designed for central gateway modules requiring CAN communication and functional safety monitoring - no display support | Choose when CAN bus interface and ASIL-B support are required; not suitable for RGB/WLED display systems due to missing drivers and PWM outputs. |
Compared with TPS658629IZWSRQ1, TPS65910A3RSLR offers reduced integration for simpler systems, while MAX20029ATG/V+T adds CAN and safety features at the expense of display functionality - neither provides the combined power, analog sensing, and display drive capability of the TPS658629IZWSRQ1 in automotive portable applications.

FAQ
What is the AEC-Q100 qualification level for TPS658629IZWSRQ1?
The TPS658629IZWSRQ1 is qualified to AEC-Q100 Grade 3, specifying operation from –40°C to +85°C ambient temperature. It meets HBM ESD Class H1C and CDM ESD Class C2 requirements. This qualification confirms suitability for non-critical automotive applications such as portable navigation and infotainment systems mounted outside the engine compartment. The TPS658629IZWSRQ1 undergoes stress testing per AEC-Q100 standards including temperature cycling, HTOL, and ESD verification.
Does TPS658629IZWSRQ1 support USB 2.0 charging compliance?
Yes, the TPS658629IZWSRQ1 includes dedicated USB current limiting circuitry that supports both 500 mA (USB 2.0 standard) and 900 mA (USB Battery Charging v1.2) profiles. This is implemented in hardware with no software configuration required, ensuring robust port protection without external components. The TPS658629IZWSRQ1 monitors current in real time and disables the path if thresholds are exceeded - a key feature for automotive USB accessory ports.
Can TPS658629IZWSRQ1 drive both RGB LEDs and WLEDs simultaneously?
Yes, the TPS658629IZWSRQ1 integrates dual RGB LED drivers and a separate constant-current WLED driver capable of 26.5 V at 25 mA. All four PWM outputs are independently programmable in frequency and duty cycle, allowing concurrent control of RGB backlight color balance and WLED brightness. This dual capability makes the TPS658629IZWSRQ1 suitable for hybrid display architectures - for example, RGB for front-panel indicators and WLED for main LCD backlight - all managed via a single I²C interface.
What package type and dimensions does TPS658629IZWSRQ1 use?
The TPS658629IZWSRQ1 uses a 169-ball plastic ball grid array (nFBGA) package designated ZWS, measuring 12.1 mm × 12.1 mm with 0.55 mm ball pitch and maximum height of 1.4 mm. Ball 1 is located in quadrant Q1 per JEDEC standard tape orientation. The package is RoHS-compliant with SnAgCu solder balls and MSL Level-3 rating (260°C peak reflow, 168-hour floor life). This compact, thermally efficient package supports high-density automotive PCB layouts.
How does the 11-channel ADC in TPS658629IZWSRQ1 support system monitoring?
The TPS658629IZWSRQ1 integrates an 11-channel SAR ADC with three operating modes: single conversion, peak detection, and averaging. It monitors internal die temperature, input voltage, and all regulated output rails - enabling real-time health diagnostics without host CPU involvement. Conversion results are stored in I²C-accessible registers, and interrupts can be generated on out-of-range conditions. This ADC functionality directly supports thermal throttling, brownout detection, and calibration routines within the TPS658629IZWSRQ1 itself.
