Application Notes
- Wide-Vin Battery-Charger Using SMBus MSP430 MCUs and bq Fuel Gauges (Rev. A)PDF, 1.0 Mb, Revision: A, File published: Jul 25, 2011
This application report describes a smart-battery charger reference design with a wide-input-voltage range. The reference design implements the System Management Bus (SMBus) protocol for communication between the MSP430 microcontroller and a SMBus-compatible battery fuel gauge. The MSP430 device interrogates the fuel gauge for voltage, current, and other parameters via SMBus. It then adjusts the p
