TPS658621AZGUT-1

The Texas Instruments TPS658621AZGUT-1 is an advanced power management unit (PMU) designed for handheld and portable electronic devices. It integrates multiple functions including battery charging, system power management, and display support.

Key electrical specifications include a supply voltage range of 3V to 18V and a low quiescent current of 870µA. The device operates reliably within a temperature range of -40°C to 85°C. It features a complete charge management solution for single-cell Li-Ion/Li-Pol batteries, with programmable adapter and USB charge outputs. Integrated power supplies include 3 programmable step-down converters with maximum outputs of 1.2A and 11 programmable general-purpose LDOs.

For display support, the TPS658621AZGUT-1 includes 4 PWM outputs and dual RGB LED drivers, along with a constant current WLED driver capable of up to 25mA. The device also incorporates system management features such as a dual input power path, USB current limiting, and over-voltage protection up to 18V.

Packaged in a compact 120-ball BGA (Microstar Junior 6x6) format, this surface-mount device is suitable for space-constrained applications. Its integrated nature reduces the need for external components, simplifying design and improving efficiency in products like smartphones and portable media players.
