Product details
Overview
TPS658621AZGUR from Texas Instruments is an advanced power management unit (PMU) integrating battery charging, three programmable step-down converters (max 1.2A each), eleven LDOs, an 11-channel ADC, dual RGB LED drivers, and a constant-current WLED driver in a single 169-pin BGA package. It serves as the central power and system management IC for handheld devices requiring dynamic power path control, thermal foldback, and display support.
For engineers reviewing the TPS658621AZGUR datasheet, TPS658621AZGUR pinout, TPS658621AZGUR application, or TPS658621AZGUR equivalent, key selection considerations include I²C-controlled power sequencing, USB/adapter dual-input charge management with 1A max current, programmable LDO output voltages (0.725V–3.3V), and integrated WLED driver with 26.5V/25mA capability.
Technical Context
The TPS658621AZGUR implements a dual-input power path architecture that dynamically selects between USB and adapter sources while managing Li-ion/Li-polymer battery charge profiles-including programmable current limits and thermal foldback. Its I²C interface enables full register-level control of all power rails, LED drivers, and ADC modes.
System management includes hardware on/off/reboot control, maskable interrupts, software reset, and comprehensive status monitoring across all supplies via Power Good signals. The 11-channel ADC supports single conversion, peak detection, and averaging modes-used for battery voltage, temperature, and system rail telemetry.
