TITPS65217C
Overview
The TPS65217C is a highly integrated single-chip Power Management IC (PMIC) optimized for powering the ARM Cortex-A8 processor series, including the Sitara AM335x. It combines three step-down converters, four low-dropout regulators, and a linear battery charger with a white LED (WLED) driver into a single 48-pin VQFN package.
Why Choose This Part
The device features password-protected I2C registers to prevent accidental changes to critical voltage rails during operation. It offers flexible power sequencing and an integrated battery path that allows the system to run from an external source while simultaneously charging a depleted battery.
Applications
Getting Started
Engineers should utilize the TPS65217EVM evaluation module to test custom power-up sequences and register settings. The PMIC is typically controlled via I2C by the host processor, and comprehensive Linux drivers are available in the mainline kernel to support the Sitara AM335x ecosystem.
