Product details
Overview
TPS659119FAIPFPRQ1 from Texas Instruments is an AEC-Q100 Grade 3 automotive power-management IC integrating three DC-DC converters (VDD1/VDD2 at 1.5 A each, VIO at 1.5 A), eight LDOs (LDO1–LDO8: 320 mA to 50 mA), RTC with 16.384-MHz crystal oscillator, EEPROM-programmable power controller, watchdog, thermal monitoring, and nine GPIOs - deployed in infotainment and ADAS systems requiring dynamic voltage scaling and robust sequencing.
For engineers reviewing the TPS659119FAIPFPRQ1 datasheet, TPS659119FAIPFPRQ1 pinout, TPS659119FAIPFPRQ1 application, or TPS659119FAIPFPRQ1 equivalent, key selection criteria include its dual-core DVFS capability via dedicated I²C interfaces, programmable boot sequence stored in on-chip EEPROM, integrated RTC with alarm/calendar, and automotive-grade thermal shutdown (150°C junction) and ESD protection (HBM ±2 kV, CDM ±500 V).
Technical Context
The TPS659119FAIPFPRQ1 implements a state-machine-based embedded power controller (EPC) with EEPROM-configurable power-up/down sequences, enabling deterministic startup for multi-rail SoC platforms. Its two core SMPS (VDD1/VDD2) support 12.5-mV dynamic voltage scaling across 0.6–1.5 V ranges, while the VIO SMPS delivers fixed 1.5/1.8/2.5/3.3 V outputs at 1.5 A.
It integrates a 16.384-MHz crystal oscillator with selectable 32-kHz clock sources (crystal, external 32-kHz, or internal RC), RTC calendar/alarm functions, and EXTCTRL interface with 1–3.7 V/V programmable gain (65 steps) for controlling external high-current converters - all coordinated under a single I²C CTL interface and dual enable signals (EN1/EN2) for independent rail control.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VDD1/VDD2 SMPS | 1.5 A output, 0.6–1.5 V range, 12.5-mV step - enables precise DVFS for dual-application-processor cores |
| VIO SMPS | 1.5 A output, selectable 1.5/1.8/2.5/3.3 V - powers I/O banks and memory interfaces |
| LDO outputs | Eight LDOs: LDO1/LDO2 (320 mA), LDO3/LDO4 (200/50 mA), LDO5–LDO8/VRTC (300 mA each) - supplies analog, digital, and backup domains |
| RTC oscillator | 16.384-MHz crystal-based, with 32-kHz output (CLK32KOUT) and calendar/alarm - maintains timekeeping during system sleep |
| EXTCTRL interface | 1–3.7 V/V gain, 65-step programmable - scales external converter voltage without additional DAC or control logic |
| GPIOs | Nine configurable GPIOs: four sequenced enables, two 10-mA LED drivers, two PWM/LED pulse generators - reduces external discrete components |
| Thermal & safety | Hot-die detection, thermal shutdown at 150°C, watchdog timer, dual reset inputs (HDRST/PWRDN) - meets ASIL-B supporting requirements |

| EN1/EN2 | Dedicated I²C-enable signals | Independent control of VDD1/VDD2 voltage scaling; support fast DVFS transitions |
| OSC16MIN/OSC16MOUT | 16.384-MHz crystal interface | Drive 12.5-pF parallel-resonant crystal; requires external load caps per layout guidelines |
| GPIO1/GPIO3 | Open-drain LED drivers | 10-mA sink capability; used with LED pulse generators for status indication |
| INT1 | Interrupt flag output | Active-low open-drain signal indicating fault, RTC alarm, or GPIO event |
| NRESPWRON/NRESPWRON2 | Power-off reset outputs | Asserted during OFF state; require external pull-up for active-high logic |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive power-management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65912101ZWSRQ1 | Same family; adds USB Type-C PD controller, removes RTC and one LDO; different pinout and EEPROM map | Targeted at USB-powered automotive accessories, not RTC-dependent systems | Select when USB PD negotiation is required and RTC functionality is unnecessary |
| MAX20029ATI/V+T | Three buck converters (2.5/1.5/1.2 A), six LDOs, no integrated RTC or EEPROM sequencing; SPI interface only | Requires external MCU for sequencing logic; lacks calendar/alarm and crystal oscillator | Select when cost-sensitive designs prioritize converter current over integrated intelligence and RTC |
