Product details
Overview
TPS658621CZGUR from Texas Instruments is an advanced power management unit (PMU) integrating three step-down converters (SM0–SM2), eleven programmable LDOs, display support functions (WLED/RGB drivers), and system management features including dual-input power path, USB current limiting, and 11-channel ADC. It delivers up to 2.0A on SM1, supports I²C control, and targets portable media players requiring compact, multi-rail power sequencing.
For engineers reviewing the TPS658621CZGUR datasheet, TPS658621CZGUR pinout, TPS658621CZGUR application, or TPS658621CZGUR equivalent, key selection criteria include its 169-pin MICROSTAR BGA (ZGU) package, -40°C to +85°C operating range, integrated over-voltage protection (18V max), software-controlled PWM mode, and hardware reboot capability.
Technical Context
The TPS658621CZGUR implements a fully integrated PMU architecture with independent regulation domains: three buck converters (SM0: ≤1.5A, SM1: ≤2.0A, SM2: ≤1.5A), eleven LDOs (seven fixed 1.25–3.3V, two factory-configurable 0.725–1.5V or 1.25–2.586V, one always-on 1.25–3.3V, one 1.70–2.475V), and four programmable PWM outputs for display backlighting and RGB control.
It features an embedded 11-channel ADC supporting single-conversion, peak-detection, and averaging modes; dual-input power path management with USB current limiting; and interrupt-driven host interface via I²C with maskable interrupts, external ADC triggering, and step-down converter mode control.

FAQ
What is the operating temperature range for the TPS658621CZGUR?
The TPS658621CZGUR is rated for operation from -40°C to +85°C ambient temperature. This industrial-grade range supports reliable performance in portable electronics exposed to variable environmental conditions, including extended outdoor use in navigation devices and media players. The device's thermal design and internal protection circuits maintain regulation stability across this full range without derating.
Does the TPS658621CZGUR support I²C communication?
Yes, the TPS658621CZGUR includes a standard I²C-compatible serial interface (SDA/SCL pins) for full register-level control. Engineers can configure output voltages, enable/disable individual rails, set PWM duty cycles, read ADC results, and monitor fault status (e.g., overtemperature, undervoltage) using standard I²C protocols. The interface operates at up to 400 kHz and supports multiple slave addresses for multi-PMU systems.
Is the TPS658621CZGUR pin-compatible with other variants in the TPS658621 family?
No, the TPS658621CZGUR is not pin-compatible with other variants such as TPS658621CZQZR due to differing package types (169-pin ZGU vs. 120-pin ZQZ) and ball layouts. While functionally similar, the ZGU and ZQZ packages have distinct pin counts, dimensions, and signal mappings. Migration requires PCB redesign. Only TPS658621CZGUT shares identical pinout and footprint with TPS658621CZGUR.
What display-related functions does the TPS658621CZGUR provide?
The TPS658621CZGUR integrates four programmable PWM outputs for display timing control, dual RGB LED drivers, and a constant-current WLED driver capable of 26.5V at 25mA. These features allow direct driving of backlight LEDs and RGB indicators without external drivers, supporting brightness control, color mixing, and fault-safe dimming - all configurable via I²C registers.
How does the TPS658621CZGUR handle power path management?
The TPS658621CZGUR implements dual-input power path management that automatically selects between USB and wall-adapter inputs, with built-in USB current limiting (programmable up to 1.5A). It prevents backfeed, manages charge current to the battery, and maintains system operation during input transitions - eliminating the need for external power-path FETs or dedicated USB limiters in portable designs.
