Product Introduction

Overview

The Texas Instruments BQ24780SRUYT is a high-efficiency, synchronous battery charger designed for space-constrained, multi-chemistry battery charging applications. This device supports a hybrid power boost mode, previously known as 'turbo boost mode,' which allows the battery to discharge energy to the system when the system's power demand exceeds the adapter's maximum power level. This feature prevents the adapter from crashing and ensures continuous system operation. The BQ24780SRUYT is particularly suited for applications requiring high accuracy power and current monitoring, such as in Intel® CPU turbo mode scenarios.
