Product details
Overview
TPS659119HAIPFPRQ1 from Texas Instruments is an AEC-Q100 Grade 3 automotive power-management IC integrating two 1.5-A dynamic voltage scaling DC-DC converters (VDD1/VDD2), one 1.5-A I/O converter (VIO), eight LDOs (LDO1–LDO8, 300 mA max each), RTC with 16.384-MHz crystal oscillator, EEPROM-programmable power controller, watchdog, thermal shutdown, and nine GPIOs - deployed in infotainment and ADAS systems requiring multi-rail sequencing.
For engineers reviewing the TPS659119HAIPFPRQ1 datasheet, TPS659119HAIPFPRQ1 pinout, TPS659119HAIPFPRQ1 application, or TPS659119HAIPFPRQ1 equivalent, key selection considerations include its HTQFP-80 package, dual I²C interfaces (CTL-I²C + SR-I²C), programmable boot sequence via on-chip EEPROM, real-time clock with 32-kHz output, and automotive-grade thermal monitoring with hot-die detection.
Technical Context
The device implements a state-machine-based embedded power controller (EPC) with EEPROM-configurable power-up/down sequences and voltage scaling timing. Its dual-core SMPS architecture supports independent I²C-controlled dynamic voltage scaling for VDD1 and VDD2, while the VIO converter delivers fixed 1.5-V/1.8-V/2.5-V/3.3-V outputs.
RTC functionality includes selectable clock sources (16.384-MHz crystal, external 32-kHz, or internal RC), calendar/alarm registers, and backup domain powered by VRTC LDO. The EXTCTRL interface provides 1–3.7-V programmable control (65 steps) of an external DC-DC converter using resistive feedback.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD1/VDD2 SMPS | 1.5-A buck converters with 0.6–1.5-V output, 12.5-mV step resolution - enables precise core voltage tuning for SoC DVFS |
| VIO SMPS | 1.5-A buck converter with fixed 1.5/1.8/2.5/3.3-V outputs - powers processor I/O and memory interfaces |
| LDO outputs | Eight LDOs: LDO1–LDO2 (320 mA), LDO3 (200 mA), LDO4 (50 mA), LDO5–LDO8 (300 mA each) - supplies analog, digital, and peripheral rails |
| RTC oscillator | 16.384-MHz crystal oscillator with fast start-up and 32-kHz CLK32KOUT - maintains timekeeping during system sleep |
| GPIO capability | Nine configurable GPIOs: four support enable sequencing, two sink 10 mA for LED drive, all support interrupt wake-up - replaces discrete logic in power tree control |
| EEPROM & control | On-chip EEPROM stores boot configuration, voltage scaling tables, and power-state transitions - eliminates external configuration memory |
| Thermal protection | Hot-die detection and thermal shutdown at 125°C junction temperature - prevents damage during sustained overload or poor PCB cooling |
Pinout & Package
TPS659119HAIPFPRQ1 is housed in an HTQFP-80 package (12.00 mm × 12.00 mm, 0.5-mm pitch) with exposed thermal pad for enhanced heat dissipation in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1/VDD2/VIO | SMPS input supplies | Accept 4–5.5-V input to feed respective buck converters - require local 10-µF X5R/X7R input capacitors |
| SW1/SW2/SWIO | Switch-node outputs | Drive external inductors (2.2 µH) and output filters - high dv/dt nodes requiring tight layout and ground shielding |
| VFB1/VFB2/VFBIO | Feedback inputs | Monitor regulated output voltages via resistor dividers - enable precision regulation (±1% typical) and dynamic scaling |
| SDA_SDI/SCL_SCK | I²C control interface | Support CTL-I²C (general-purpose) and SR-I²C (VDD1/VDD2 scaling only) - require external 1.2-kΩ pull-ups to VDDIO |
| EN1/EN2 | Dedicated enable signals | Hardware-triggered control for VDD1/VDD2 sequencing - bypass I²C for critical power-on timing |
| GPIO0–GPIO8 | Configurable I/Os | Four support power-up enable sequencing; two sink 10 mA for LED pulse generation; all support maskable interrupts |
| OSC16MIN/OSC16MOUT | Crystal oscillator terminals | Interface with 16.384-MHz fundamental-mode crystal - require load capacitance matching per crystal spec |
| CLK32KOUT | 32-kHz clock output | Provides low-power timing reference for MCU sleep modes - disabled in ACTIVE/SLEEP states, active only in OFF |

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 HTQFP-80 package; adds USB Type-C PD controller and removes RTC; LDO count reduced to six | Better suited for connectivity-focused ECUs (e.g., USB-C docking); lacks calendar/alarm functionality required for time-sensitive infotainment | Select when USB-C power delivery integration is prioritized over RTC and full LDO complement |
| MAX20029ATG/V+T | 3.5-MHz synchronous buck (1.2-A) + six LDOs (300 mA max); no EEPROM, no RTC, no GPIOs; TQFN-32 package | Targeted at cost-sensitive body electronics; lacks programmable sequencing, real-time clock, and LED drivers needed for head units | Choose for simpler, lower-pin-count applications where EEPROM configuration and RTC are unnecessary |
Compared with TPS659119HAIPFPRQ1, TPS65912101ZWSRQ1 trades RTC and two LDOs for USB-C PD control, while MAX20029ATG/V+T offers smaller footprint and lower cost but omits EEPROM sequencing, RTC, and GPIO flexibility - making TPS659119HAIPFPRQ1 optimal for complex infotainment and ADAS SoC power trees.

FAQ
What is the operating temperature range qualified for TPS659119HAIPFPRQ1?
TPS659119HAIPFPRQ1 is AEC-Q100 qualified for Grade 3 operation, supporting ambient temperatures from –40°C to +85°C. This rating covers typical under-dash and center-console automotive environments. Junction temperature must remain ≤125°C under all conditions, enforced by integrated thermal shutdown circuitry that triggers at 125°C and holds until die cools below 110°C hysteresis threshold. The HTQFP-80 package's RθJA of 34.1°C/W requires appropriate PCB copper pour and thermal vias for reliable operation at maximum load.
How does the EEPROM programming work for TPS659119HAIPFPRQ1 power sequencing?
TPS659119HAIPFPRQ1 contains on-chip EEPROM that stores boot configuration, voltage scaling tables, power-state transitions, and GPIO mappings. Programming is performed via the CTL-I²C interface using TI's Power Management Studio software or custom firmware. Each EEPROM location corresponds to specific register fields controlling delay timers, enable dependencies, and rail voltage targets. The device boots using these stored values without host intervention, enabling deterministic startup even after power loss. Factory-default settings are retained unless overwritten, and write cycles are rated for >100,000 endurance.
Can TPS659119HAIPFPRQ1 support both crystal and external 32-kHz clock for the RTC?
Yes, TPS659119HAIPFPRQ1 supports three RTC clock sources: internal 32-kHz RC oscillator, external 32-kHz square-wave clock applied to OSCEXT32K pin, or 16.384-MHz crystal connected to OSC16MIN/OSC16MOUT. The source is selected via EEPROM-configurable register bits. Crystal mode provides highest accuracy (±20 ppm typical), while external 32-kHz input enables synchronization with system master clock. The internal RC oscillator serves as fallback during crystal startup or failure. All modes retain calendar/time data in VRTC domain powered by dedicated LDO.
What are the key differences between the CTL-I²C and SR-I²C interfaces on TPS659119HAIPFPRQ1?
TPS659119HAIPFPRQ1 features two independent I²C interfaces: CTL-I²C (SDA_SDI/SCL_SCK) provides full register access for configuration, monitoring, and control of all resources, while SR-I²C (EN1/EN2 pins multiplexed as SDA/SCL) is dedicated exclusively to dynamic voltage scaling of VDD1 and VDD2. SR-I²C operates at higher speed and lower latency, enabling real-time core voltage adjustments during processor load changes. CTL-I²C remains available for non-critical tasks like LDO configuration or GPIO control, preventing bus contention during DVFS events.
Does TPS659119HAIPFPRQ1 include hardware reset supervision for automotive safety compliance?
Yes, TPS659119HAIPFPRQ1 integrates multiple reset supervision features for automotive safety: HDRST (cold reset input) initiates full system reset on button press or external signal; PWRDN (thermal reset input) triggers safe shutdown upon die overheating; NRESPWRON and NRESPWRON2 provide open-drain reset outputs synchronized with power state transitions. These signals meet ISO 26262 ASIL-B readiness requirements when used with external watchdogs. The device also includes a programmable watchdog timer with windowed timeout and interrupt capability, configurable via EEPROM to match system-level fault-handling timing budgets.
