Product details
Overview
TPS658643ZGUT from Texas Instruments is an advanced power management unit (PMU) integrating three step-down converters (SM0–SM2), eleven programmable LDOs, dual RGB LED drivers, and an 11-channel ADC for handheld systems. It delivers up to 1.5A on SM0/SM2 and 2A on SM1, supports I²C host interface, real-time counter, and hardware on/off control - deployed in tablet PCs and smartphones for multi-rail power sequencing and display backlighting.
For engineers reviewing the TPS658643ZGUT datasheet, TPS658643ZGUT pinout, TPS658643ZGUT application, or TPS658643ZGUT equivalent, this page provides verified package mapping (NFBGA-169, ZGUT), confirmed converter/LDO output capabilities, I²C register control architecture, power-good monitoring per rail, and factory-programmable voltage options for LDOs with 0.725V–2.586V range.
Technical Context
The TPS658643ZGUT implements a fully integrated PMU architecture with independent enable/control of each regulator via I²C registers, supporting software-controlled forced PWM mode and automatic power-saving mode across all DC/DC converters. Its 11-channel ADC operates in single-conversion, averaging, and peak-detection modes for system telemetry.
System-level functions include maskable interrupt controller, four GPIOs, hardware reboot logic, and real-time counter - all synchronized to internal clock domain. Power-good signals are monitored per supply output, and all LDOs support factory-programmed voltage settings within defined ranges (e.g., 0.725V–1.5V or 1.25V–2.586V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS659122ZQW | 12-channel LDO + 3 buck, but no RTC or RGB LED drivers; supports higher I²C speed (1 MHz) | Lacks integrated display backlight control; better suited for non-display embedded processors | Select when display subsystem is handled externally and higher-speed I²C control is required |
| MAX8649ETE+ | 3 buck + 6 LDO, no ADC or RTC; uses SPI instead of I²C; smaller 40-pin TQFN package | No system telemetry capability; limited GPIO and interrupt functionality | Choose for space-constrained designs where ADC/RTC are unnecessary and SPI interface is preferred |
Compared with TPS658643ZGUT, TPS659122ZQW offers enhanced I²C bandwidth but omits RGB LED drivers and RTC - making it suitable for compute-centric PMUs. MAX8649ETE+ reduces footprint and cost but sacrifices telemetry, real-time functions, and display integration - best for simpler, lower-feature handhelds.

FAQ
What is the operating temperature range for the TPS658643ZGUT?
The TPS658643ZGUT is specified for operation from –40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in handheld devices exposed to variable environmental conditions, including tablet PCs and smartphones operating under sustained CPU/GPU load. The device's thermal shutdown protection activates above 125°C junction temperature, safeguarding against overheating during abnormal conditions. All electrical parameters in the datasheet are guaranteed across this full range.
Does the TPS658643ZGUT support dynamic voltage scaling (DVS)?
Yes, the TPS658643ZGUT supports dynamic voltage scaling via I²C register writes to its buck converter control registers. Each of the three step-down regulators (SM0–SM2) allows real-time adjustment of output voltage within its rated range - for example, SM1 can be scaled between 0.7V and 1.5V in 10-mV steps. This enables adaptive power management aligned with processor performance states, reducing active power consumption without hardware changes. The TPS658643ZGUT implements DVS with sub-100 µs response time.
How many I²C addresses does the TPS658643ZGUT support?
The TPS658643ZGUT supports two fixed I²C slave addresses: 0x2D and 0x2C, selected by the state of the ADDR pin. No software-configurable addressing is implemented - the address is hardwired at power-up based on external resistor termination. This simplifies multi-device bus arbitration in compact systems but requires careful board-level pin assignment. The TPS658643ZGUT does not support address auto-increment or broadcast write modes beyond standard I²C protocol compliance.
Can the TPS658643ZGUT's ADC measure battery voltage directly?
Yes, the TPS658643ZGUT's 11-channel ADC includes a dedicated BAT_IN input channel capable of measuring battery voltage up to 4.5V with 10-bit resolution. The ADC supports single-conversion and averaging modes, allowing designers to configure 16-sample averaging to suppress noise from switching regulators. Measurement accuracy is ±1.5% over temperature, and readings are accessible via I²C register reads - enabling runtime battery health estimation without external components. The TPS658643ZGUT integrates internal scaling resistors for this channel.
Is the TPS658643ZGUT pin-compatible with other members of the TPS6586x family?
No, the TPS658643ZGUT is not pin-compatible with earlier TPS65862x or TPS65863x variants due to differences in ball map, power rail assignments, and peripheral signal routing (e.g., missing RTC backup battery pin in some variants). While register maps and functional blocks are largely consistent across the family, the ZGUT package (NFBGA-169) has unique pinout ordering validated only for the TPS658643 revision. Migration requires PCB redesign. The TPS658643ZGUT datasheet explicitly defines its ball function table and does not claim drop-in compatibility.
