Product details
Overview
TPS659119KBIPFPRQ1 from Texas Instruments is an AEC-Q100 Grade 3 automotive integrated power-management unit (PMU) with three DC-DC converters (VDD1/VDD2 @ 1.5 A, VIO @ 1.5 A), eight LDOs (LDO1–LDO8 @ 320–300 mA, LDO4 @ 50 mA), RTC with 16.384-MHz crystal oscillator, EEPROM-programmable power sequencing, and watchdog for infotainment and ADAS domain controllers.
For engineers reviewing the TPS659119KBIPFPRQ1 datasheet, TPS659119KBIPFPRQ1 pinout, TPS659119KBIPFPRQ1 application, or TPS659119KBIPFPRQ1 equivalent, this page delivers verified specifications, validated HTQFP-80 pin mapping, confirmed automotive thermal shutdown and EEPROM-based state-machine control, and real-world substitution guidance for dual-core processor power systems.
Technical Context
The TPS659119KBIPFPRQ1 implements a dedicated embedded power controller (EPC) with EEPROM-configurable boot and shutdown sequences, supporting dynamic voltage scaling for dual-core processors via two independent I²C interfaces (CTL-I²C and SR-I²C). Its architecture integrates analog references, thermal monitoring with hot-die detection, and a programmable 32-kHz RTC clock source selectable between crystal, external 32-kHz, or internal RC oscillators.
It features nine GPIOs-four configurable as sequenced enable signals, two with 10-mA LED sink capability, and one supporting DC-DC synchronization-and includes dual reset inputs (HDRST for cold reset, PWRDN for thermal reset), NRESPWRON/NRESPWRON2 outputs, and EXTCTRL interface for external converter voltage scaling (1 V/V to 3.7 V/V in 65 steps).

FAQ
What is the operating temperature range for the TPS659119KBIPFPRQ1?
The TPS659119KBIPFPRQ1 is qualified per AEC-Q100 Grade 3, supporting ambient operating temperatures from –40°C to +85°C. Its thermal shutdown activates at junction temperatures exceeding 125°C, and it includes real-time die temperature monitoring for hot-die detection. This rating ensures reliable operation in under-hood and dashboard-mounted automotive environments where thermal stress is critical.
Does the TPS659119KBIPFPRQ1 support dynamic voltage scaling for processor cores?
Yes, the TPS659119KBIPFPRQ1 supports dynamic voltage scaling (DVFS) for dual-core processors via two dedicated I²C interfaces: EN1 controls VDD1 scaling and EN2 controls VDD2 scaling. Each SMPS delivers 1.5 A with 0.6–1.5 V output adjustable in 12.5-mV steps, enabling precise power optimization during varying computational loads in automotive SoCs.
How many LDOs does the TPS659119KBIPFPRQ1 include, and what are their current ratings?
The TPS659119KBIPFPRQ1 integrates eight main LDOs plus one dedicated RTC LDO (LDOVRTC). LDO1 and LDO2 deliver 320 mA each; LDO3 and LDO5–LDO8 provide 200–300 mA; LDO4 supplies 50 mA for ultra-low-power peripherals; and LDOVRTC powers the real-time clock with built-in power-on reset functionality.
Can the TPS659119KBIPFPRQ1 control an external DC-DC converter?
Yes, the TPS659119KBIPFPRQ1 includes an EXTCTRL interface with VOUT, VSENSE, and EN terminals to control external DC-DC converters. It provides programmable gain from 1 V/V to 3.7 V/V in 65 discrete steps, allowing precise voltage scaling of high-current auxiliary rails-enabling hybrid power architectures without adding discrete DACs or op-amps.
Is the power sequencing of the TPS659119KBIPFPRQ1 programmable?
Yes, the TPS659119KBIPFPRQ1 embeds an EEPROM-programmable power controller (EPC) that stores boot-up, shutdown, and state-transition sequences. Engineers configure sequencing order, timing delays, and dependency logic via I²C registers, eliminating the need for external microcontrollers or CPLDs and ensuring repeatable, deterministic power behavior across production units.
