Supply TI BQ24800RUYR SMBus 1 To 4 Cell Buck Battery Charge Controller With Peak Power

Shenzhen Mingjiada Electronics Co., Ltd.——Long Term Supply TI (BQ24800RUYR) High-Efficiency, Synchronous Buck Multi-Chemistry Battery Charger, Below are product details for BQ24800RUYR:

Basic Information:

Part Number: BQ24800RUYR

Package: WQFN-28

Type: Buck Battery Charge Controller

Product Details: BQ24800RUYR——SMBus 1- to 4-Cell Buck Battery Charge Controller With Peak Power, Hybrid Power Boost and Battery Only Boost Modes.

BQ24800RUYR is a high-efficiency, synchronous buck multi-chemistry battery charger supporting 1-, 2-, 3-, or 4-series Li+ cells, or other battery chemistries up to 19.2V.

Through SMBus, a host microcontroller programs charge current, charge voltage, input current limit and discharge current limit with high regulation accuracies. Additionally, the BQ24800RUYR supports a two level input current limit (Peak Power mode) to fully utilize the adapter capabilities and reduce battery discharge.

BQ24800RUYR provides adapter current (IADP), battery discharge current (IDCHG), and system power (PMON) signals to the host microcontroller and outputs the PROCHOT signal to throttle back CPU speed when needed.

BQ24800RUYR supports hybrid power boost mode to boost the battery voltage to supplement the adapter when system power demand is temporarily higher than the adapter is able to provide. When the adapter is not present, the BQ24800RUYR supports battery only boost mode to boost the battery voltage above the minimum system operating voltage, providing more headroom to support system transients.
