Application Notes
- bq20z75/95 Printed Circuit Board Layout GuidePDF, 802 Kb, File published: Dec 20, 2007
New single-package IC fuel gauges can significantly simplify PCB layout. Attention to layout, however, is critical to the success of any battery management circuit board. The mixture of high-current paths with an ultralow-current microcontroller creates the potential for troublesome design issues. This document presents guidelines that can ensure a stable and well performing project. - Differences Between the bq20z70/z75/z80/z90/z95 Impedance TrackTM Gas GaugesPDF, 44 Kb, File published: Apr 3, 2007
