Product details
Overview
TPS658643ZQZT from Texas Instruments is an advanced power management unit (PMU) integrating three step-down converters (SM0–SM2), eleven programmable LDOs, dual RGB LED drivers, 11-channel ADC, real-time counter, and I²C interface - all in a single NFBGA-169 package. It delivers up to 1.5A on SM0/SM2 and 2A on SM1, supporting core voltage regulation and display backlighting in portable computing devices.
For engineers reviewing the TPS658643ZQZT datasheet, TPS658643ZQZT pinout, TPS658643ZQZT application, or TPS658643ZQZT equivalent, key selection criteria include multi-rail sequencing capability, integrated system monitoring (Power Good, software reset, interrupt controller), and factory-programmable LDO output ranges for SoC power domains in tablets and smartphones.
Technical Context
The TPS658643ZQZT implements a fully integrated PMU architecture with independent control of each regulator via I²C register access. Its 11-channel ADC supports single-conversion, averaging, peak-detection, and software-triggered modes for battery and thermal monitoring.
System-level functions include hardware ON/OFF and reboot control, maskable interrupts, four GPIOs, and real-time counter for time-stamped event logging - enabling autonomous power state management without host CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS659122ZQZT | Higher integration: adds USB OTG PHY, HDMI power switch, and enhanced RTC; same NFBGA-169 footprint but different pin mapping | Targeted at newer TI Sitara AM335x/AM437x platforms with USB/HDMI interfaces | Select when USB OTG or HDMI power control is required; not pin-compatible with TPS658643ZQZT |
| MAX8649ETL+ | Single 3A buck + 6 LDOs only; no ADC, RTC, LED drivers, or I²C; 24-pin QFN package | Used in simpler embedded systems where full PMU features are unnecessary | Choose for cost-sensitive designs needing only basic multi-rail regulation without system monitoring |
Compared with TPS658643ZQZT, TPS659122ZQZT offers expanded connectivity but requires layout revision due to non-identical pinout, while MAX8649ETL+ provides minimal regulation in a smaller package but lacks diagnostic and display functions essential for handheld UI subsystems.

FAQ
What is the maximum output current capability of each buck converter in the TPS658643ZQZT?
The TPS658643ZQZT provides three buck converters: SM0 and SM2 each deliver up to 1.5A continuous output current, while SM1 supports up to 2A. These ratings assume proper PCB thermal design and ambient temperature ≤85°C. The TPS658643ZQZT datasheet specifies current limits under typical operating conditions with recommended external components.
Does the TPS658643ZQZT support hardware power sequencing for multi-rail SoCs?
Yes, the TPS658643ZQZT supports configurable power-on and power-off sequencing through its I²C interface and internal register settings. Each regulator can be enabled/disabled in user-defined order with programmable delays. This ensures safe startup and shutdown of complex SoCs like NVIDIA Tegra or TI OMAP, preventing latch-up or back-powering issues. The TPS658643ZQZT implements this without external timers or logic.
Can the TPS658643ZQZT's ADC measure battery voltage and temperature simultaneously?
Yes, the TPS658643ZQZT's 11-channel ADC supports simultaneous sampling of multiple inputs including battery voltage (VBAT), die temperature, and auxiliary analog signals. It offers three operating modes - single conversion, averaging, and peak detection - allowing designers to trade off speed versus accuracy. All measurements are accessible via I²C registers, and the TPS658643ZQZT includes built-in calibration data for improved accuracy.
What is the function of the INT_N pin on the TPS658643ZQZT?
The INT_N pin on the TPS658643ZQZT is an open-drain interrupt output that asserts low when any monitored condition triggers an alert - such as Power Good failure, thermal warning, ADC threshold exceedance, or RTC alarm. It connects directly to a host processor's GPIO or interrupt controller. The TPS658643ZQZT allows masking individual sources via I²C, making INT_N a centralized fault-signaling node without requiring additional logic.
Is the TPS658643ZQZT RoHS compliant and what is its moisture sensitivity level?
Yes, the TPS658643ZQZT is RoHS compliant with SnAgCu (SAC305) ball finish. Its moisture sensitivity level is MSL-3 per JEDEC J-STD-020, with a peak reflow temperature of 260°C and floor life of 168 hours at ≤30°C/60% RH. The TPS658643ZQZT package marking "658643ZQZ" appears on the top surface, and full packaging details are specified in TI's official packaging addendum.
