Product details
Overview
TPS6522005RHBREP from Texas Instruments is a radiation-hardened, extended-temperature Power Management IC (PMIC) integrating three synchronous step-down DC/DC converters (1×3.5A, 2×2A) and four LDOs (2×400mA, 2×300mA), all programmable via I²C for dynamic voltage scaling and power sequencing in industrial MPUs like AM62x/AM64x. It operates across –55°C to +125°C and supports defense/aerospace applications.
For engineers reviewing the TPS6522005RHBREP datasheet, TPS6522005RHBREP pinout, TPS6522005RHBREP application, or TPS6522005RHBREP equivalent, key selection criteria include its triple-buck architecture with 2.3 MHz switching, EEPROM-programmable rail voltages, multi-PMIC scalability for >14-rail systems, and functional safety capability under extreme ambient conditions.
Technical Context
The TPS6522005RHBREP implements a fully configurable power tree with independent control of three buck converters-BUCK1 (3.5A, 0.6–3.4V), BUCK2/BUCK3 (2A each, 0.6–3.4V)-and four LDOs: LDO1/LDO2 (400mA, 0.6–3.4V, bypass/load-switch capable), LDO3/LDO4 (300mA, 1.2–3.3V, load-switch configurable). All rails support dynamic voltage scaling and programmable power-up/down sequencing.
Its I²C interface (standard/fast/fast-mode+) enables real-time configuration and monitoring, while two GPOs, one GPIO, three multi-function pins (MODE/STBY, MODE/RESET, VSEL_SD/VSEL_DDR), and EEPROM-based NVM programming allow seamless integration into SoC-based systems requiring robust, field-updatable power control across extended temperature and reliability requirements.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6521905RHBREP | Same 32-pin QFN package and –55°C to +125°C rating, but integrates only two 3-A bucks and three LDOs; lacks second BUCK2 and one LDO; no VSEL_SD/VSEL_DDR pin | Supports simpler SoCs with fewer rail requirements; insufficient for full AM64x power tree | Select when system needs lower channel count and reduced sequencing complexity without SD-card voltage switching |

FAQ
What is the operating temperature range of the TPS6522005RHBREP?
The TPS6522005RHBREP is characterized and guaranteed to operate across an ambient temperature range of –55°C to +125°C, with junction temperature support up to +150°C. This extended range meets stringent requirements for defense, aerospace, and industrial applications where thermal extremes are routine. The device undergoes rigorous testing per its Enhanced Product (EP) qualification standard, ensuring reliability under continuous operation at these limits. TPS6522005RHBREP's thermal design includes a dedicated PGND thermal pad to maintain safe junction temperatures under full load.
Does the TPS6522005RHBREP support dynamic voltage scaling (DVS)?
Yes, the TPS6522005RHBREP supports dynamic voltage scaling on all three buck converters via its I²C interface, enabling real-time adjustment of output voltages during system operation. This feature aligns with processor DVFS states-for example, lowering BUCK1 voltage when an AM64x core enters idle mode-to reduce dynamic power consumption. DVS is implemented through programmable register writes to the buck feedback reference, with voltage steps of 25 mV (0.6–1.4 V) or 100 mV (1.5–3.4 V). TPS6522005RHBREP's EEPROM stores default DVS tables for automatic execution at power-up.
Can the TPS6522005RHBREP be used in multi-PMIC configurations?
Yes, the TPS6522005RHBREP supports synchronized multi-PMIC operation using its GPIO pin to coordinate power-up/down sequencing across two or more devices. This capability enables scalable power management for systems requiring more than 14 rails-such as high-end radar processors or AI inference accelerators-while maintaining deterministic timing and fault isolation. The GPIO pin acts as a level-sensitive synchronization input, and the TPS6522005RHBREP's sequencer ensures inter-device alignment within defined slot extensions. TPS6522005RHBREP's documentation specifies timing margins and configuration registers required for reliable multi-device handshake.
What are the key differences between the LDOs in the TPS6522005RHBREP?
The TPS6522005RHBREP integrates four LDOs grouped into two functionally distinct pairs: LDO1/LDO2 (400 mA, 0.6–3.4 V) support bypass mode and SD-card I/O voltage switching via the VSEL_SD pin, while LDO3/LDO4 (300 mA, 1.2–3.3 V) are optimized for fixed-voltage analog supplies and also support load-switch mode. LDO1/LDO2 accept input voltages from 1.5 V to 5.5 V (or 1.5–3.6 V in bypass), whereas LDO3/LDO4 require 2.2–5.5 V input. All four LDOs are EEPROM-configurable and monitor-enabled. TPS6522005RHBREP's pinout assigns dedicated PVIN_LDO1, PVIN_LDO2, and shared PVIN_LDO34 inputs to enforce these domain separations.
Is the TPS6522005RHBREP pin-compatible with other TPS6522xx-EP devices?
No, the TPS6522005RHBREP is not pin-compatible with earlier TPS6522xx-EP variants such as TPS6521905RHBREP due to differences in pin assignment-including the presence of VSEL_SD/VSEL_DDR, dual LX_B1 pins, and distinct multi-function pin allocations (e.g., MODE/STBY vs. dedicated STBY). While both use the same 32-pin QFN (RHB) package footprint, signal mapping and power domain routing differ significantly. Migration requires PCB layout revision and firmware register updates. TPS6522005RHBREP's datasheet explicitly documents its unique pin functions in Table 4-1 and warns against mechanical substitution without electrical validation.
