Product details
Overview
TPS659119BAIPFPRQ1 from Texas Instruments is an AEC-Q100 Grade 3 automotive power-management IC integrating three DC-DC converters (VDD1/VDD2 @ 1.5 A each, VIO @ 1.5 A), eight LDOs (LDO1–LDO8 @ 320 mA to 50 mA), RTC with 16.384-MHz crystal oscillator, EEPROM-programmable power controller, and nine GPIOs - designed for infotainment and ADAS processors requiring dynamic voltage scaling and robust sequencing.
For engineers reviewing the TPS659119BAIPFPRQ1 datasheet, TPS659119BAIPFPRQ1 pinout, TPS659119BAIPFPRQ1 application, or TPS659119BAIPFPRQ1 equivalent, this page delivers verified specifications including VDD1/VDD2 output range (0.6–1.5 V in 12.5-mV steps), EXTCTRL programmability (1–3.7 V/V, 65 steps), thermal shutdown, watchdog, and I²C-controlled LDO regulation - critical for automotive SoC power architecture validation.
Technical Context
The TPS659119BAIPFPRQ1 implements a dedicated embedded power controller (EPC) with EEPROM-based state-machine sequencing, enabling configurable boot-up, sleep/wake transitions, and fault recovery without host processor intervention. It supports dual-core DVFS via two independent I²C interfaces (CTL-I²C and SR-I²C) for real-time VDD1/VDD2 voltage scaling.
Its RTC subsystem integrates a fast-start 16.384-MHz crystal oscillator, selectable 32-kHz clock sources (crystal/external RC/internal), calendar/alarm functions, and VRTC LDO - all operating from a backup domain isolated from main power rails. The device also provides two LED pulse generators and one PWM generator for status indication.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive power-management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS659121A0RSLRQ1 | Same 80-pin HTQFP package; adds fourth DC-DC (VDD3); removes RTC and VRTC LDO; higher GPIO count (12). | Targeted at compute-heavy ADAS ECUs needing extra core rail but no timekeeping; unsuitable for telematics requiring RTC persistence. | Select when fourth SMPS is required and RTC functionality is unnecessary; verify GPIO mapping against existing layout. |
| MAX20029ATG/V+T | 3-channel buck + 8-channel LDO; no EEPROM, RTC, or GPIOs; integrated FETs; smaller 48-pin TQFN. | Designed for cost-sensitive body control modules; lacks programmable sequencing, DVFS support, and automotive-grade RTC. | Choose for non-processor applications where fixed sequencing suffices and footprint reduction is prioritized over flexibility. |
Compared with TPS659119BAIPFPRQ1, TPS659121A0RSLRQ1 extends core rail capability but sacrifices RTC functionality, while MAX20029ATG/V+T reduces integration depth and programmability to achieve lower cost and smaller footprint - making each suitable only for distinct automotive subsystem architectures.
