Product details
Overview
TPS6591104A2ZRC from Texas Instruments is an integrated power management IC (PMIC) featuring three step-down DC-DC converters (VDD1, VDD2, VIO), one external-FET controller (VDDCtrl), eight programmable LDOs, embedded power controller with EEPROM, real-time clock (RTC), and nine configurable GPIOs. It delivers 1.5 A at 0.6–1.5 V on VDD1, 1.5 A at 0.6–2.2 V on VDD2, and 1.3 A at 1.5 V on VIO - optimized for dual-core application processors in portable systems powered by single-cell Li-ion or 5-V input.
For engineers reviewing the TPS6591104A2ZRC datasheet, TPS6591104A2ZRC pinout, TPS6591104A2ZRC application, or TPS6591104A2ZRC equivalent, this device supports dynamic voltage scaling via dedicated I²C interface, thermal shutdown protection, 32.768-kHz RTC oscillator (crystal or RC), and programmable power sequencing - critical for NVIDIA T30-based embedded designs requiring multi-rail coordination and low-power state management.
Technical Context
The TPS6591104A2ZRC implements a hierarchical power architecture: two core SMPS (VDD1/VDD2) support adaptive voltage scaling under I²C control, while VIO supplies I/O and memory rails. The VDDCtrl controller drives external high-current FETs with programmable slew rate and overcurrent protection via TRIP pin.
Its embedded power controller (EPC) executes EEPROM-programmable boot-up, sleep/wake sequences, and fault recovery logic. The RTC includes calendar, alarm, and backup battery charging (VBACKUP), and the nine GPIOs support LED driving (10-mA sink), interrupt generation, and system-level synchronization - all managed through register-mapped I²C (CTL-I²C and voltage-scaling I²C).

FAQ
What is the primary application target for the TPS6591104A2ZRC?
The TPS6591104A2ZRC is specifically designed for NVIDIA T30-based platforms, delivering coordinated power to dual ARM Cortex-A9 cores, DDR2/DDR3 memory, and peripheral I/O. Its EEPROM-programmable sequencing and DVS-capable SMPS make it ideal for smartphones and tablets where dynamic power optimization is critical. The TPS6591104A2ZRC integrates all essential rails - including RTC, LDOs, and GPIOs - into a single 98-pin BGA package.
Does the TPS6591104A2ZRC support external crystal or internal oscillator for RTC?
Yes, the TPS6591104A2ZRC supports both 32.768-kHz external crystal (via OSC32KIN/OSC32KOUT pins) and an internal 32-kHz RC oscillator. When a crystal is not connected, the internal oscillator automatically takes over to maintain RTC functionality - ensuring continuous timekeeping during board-level cost reduction or layout constraints. The TPS6591104A2ZRC's RTC retains calendar, alarm, and backup registers even during main power loss if VBACKUP is supplied.
How many LDOs does the TPS6591104A2ZRC provide, and what are their key specifications?
The TPS6591104A2ZRC integrates eight main LDOs plus one dedicated RTC LDO (VRTC). Five LDOs (LDO3, LDO4, LDO5, LDO6, LDO7, LDO8) support 1.0–3.3 V in 100-mV steps; LDO1, LDO2, and LDO4 support 1.0–3.3 V in finer 50-mV steps. Output currents range from 50 mA (LDO4) to 320 mA (LDO1/LDO2) and 300 mA (LDO5/LDO6/LDO7/LDO8). All are fully I²C-controllable and include 5-µA pull-downs on feedback inputs for stability.
Can the EN1 and EN2 pins of the TPS6591104A2ZRC be used for purposes other than enabling power rails?
Yes - EN1 and EN2 are multiplexed pins that can alternatively serve as a dedicated high-speed I²C interface (clock and data) for dynamic voltage scaling of VDD1 and VDD2. This dual-mode capability eliminates bus contention between general control commands and time-critical voltage adjustments. The TPS6591104A2ZRC's internal state machine handles mode selection based on EEPROM configuration, and external pull-ups ensure safe default behavior during power-up.
What thermal protection features does the TPS6591104A2ZRC include?
The TPS6591104A2ZRC includes thermal shutdown protection that triggers at 150°C junction temperature, halting all SMPS and LDO outputs to prevent damage. It also features hot-die detection with maskable interrupt (INT1) for early warning before shutdown. Thermal metrics are validated for the 98-pin ZRC package, and the device supports thermal derating down to –45°C ambient. The TPS6591104A2ZRC's thermal monitoring circuitry is self-contained - no external sensors or firmware polling required.
