Overview
The TPS65910A3A1RSLR is an integrated power-management IC designed by Texas Instruments. This device is part of the TPS65910 family and is specifically tailored for applications powered by a single Li-Ion or Li-Ion polymer battery cell, 3-series Ni-MH cells, or a 5-V input. It is particularly suited for systems requiring multiple power rails, such as those based on OMAP processors.
The TPS65910A3A1RSLR is packaged in a 48-QFN package and features an embedded power controller (EPC) to manage the power sequencing requirements of the system. It also includes an RTC (Real-Time Clock) resource with an oscillator for a 32.768-kHz crystal or a built-in RC oscillator, along with date, time, and calendar capabilities.
