Product details
Overview
TPS658621AZGUT-1 from Texas Instruments is an advanced power management unit (PMU) integrating battery charging, three programmable step-down converters (max 1.2A), eleven LDOs, dual RGB LED drivers, constant-current WLED driver (26.5V/25mA), and 11-channel ADC for handheld devices. It supports dual-input power path, USB current limiting, and I²C-controlled system management in a 6×6 mm BGA package.
For engineers reviewing the TPS658621AZGUT-1 datasheet, TPS658621AZGUT-1 pinout, TPS658621AZGUT-1 application, or TPS658621AZGUT-1 equivalent, key selection criteria include integrated Li-ion charge management (1A max), programmable step-down output capability, WLED driver compliance with 26.5V/25mA spec, thermal foldback protection, and I²C interface for host-controlled diagnostics and fault handling.
Technical Context
The TPS658621AZGUT-1 implements a dual-input power path architecture with automatic selection between adapter and USB inputs, supporting dynamic power management and thermal foldback to prevent overheating during high-load charging. Its I²C interface enables full register-level control of converter modes, LDO voltages, LED brightness, and ADC operating modes (single, peak detection, averaging).
System-level functions include hardware on/off/reboot control, maskable interrupt controller, external ADC triggering, and power-good monitoring across all regulated outputs. The 11-channel ADC supports factory-configurable input ranges and three distinct conversion modes for flexible sensor and battery monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65910A3RSLR | 10-buck + 10-LDO PMU; no integrated WLED driver; includes RTC and more GPIOs; 196-pin BGA | Targets higher-complexity tablets with RTC dependency and greater I/O needs; lacks 26.5V WLED drive capability | Select when RTC, additional GPIOs, or higher buck count outweigh need for integrated WLED driver |
| MAX8649ETE+T | Single 1.2A buck + 4 LDOs; no battery charger, no ADC, no LED drivers; 16-pin TQFN | Suitable for simpler embedded systems without display or charging requirements; significantly smaller footprint but far less integration | Select only for cost- and space-constrained designs omitting battery management and display support |
Compared with TPS658621AZGUT-1, TPS65910A3RSLR offers greater digital integration (RTC, GPIOs) but sacrifices WLED driver capability and uses a larger package, while MAX8649ETE+T provides minimal power regulation in compact form but requires external charger, ADC, and LED drivers - making it unsuitable as a drop-in replacement.

Does the TPS658621AZGUT-1 include a WLED driver, and what are its key electrical specs?
Yes, the TPS658621AZGUT-1 integrates a constant-current WLED driver capable of delivering up to 26.5V at 25mA. It supports programmable current levels and brightness control via I²C, includes over-voltage protection, and is designed for driving white LED strings in handheld displays. The TPS658621AZGUT-1 does not require external current-setting resistors or boost inductors for basic operation.
How many step-down converters does the TPS658621AZGUT-1 integrate, and what is their output capability?
The TPS658621AZGUT-1 integrates three independent programmable step-down converters, each capable of delivering up to 1.2A continuous output current. Their output voltages and operating modes (PWM or automatic PFM) are fully configurable via I²C. These buck regulators support adaptive voltage scaling and are used to power processor cores, memory, and other high-current subsystems in handheld devices.
What type of interface does the TPS658621AZGUT-1 use for configuration and monitoring?
The TPS658621AZGUT-1 uses a standard I²C-compatible serial interface (I2C_SDA/I2C_SCL) for full register-level configuration, status monitoring, and interrupt handling. All functional blocks-including buck converters, LDOs, charger, ADC, and LED drivers-are accessible through this interface. The TPS658621AZGUT-1 also provides an active-low INT_N pin for hardware interrupt signaling.
Is the TPS658621AZGUT-1 suitable for automotive applications?
No, the TPS658621AZGUT-1 is not qualified for automotive applications. Texas Instruments does not designate this part as ISO/TS 16949-compliant or AEC-Q200-qualified.
