Part Number: BQ2057W Other Parts Discussed in Thread: BQ2057 , MSP430F5529 Good evening....
I am using a BQ2057W (8.4V) part and want to take the STAT output to an MSP430 input....The MSP430 is a 3.3V part.....The STAT will be driven, low, high or tri…
Part Number: BQ2057W Can someone explain to me why I cannot turn the input voltage above 10.2V to charge my 8.4V batteries? I am using high side sensing (100 mOhms) with a P-FET. My input current is 1.4A and output is charging at about 1A (see Figure…
Part Number: BQ2057W Hi.
I design a charger batteries board. I use 2 cell batteries 18650 3.7V@3.400mAh.
Charging is Ok. But when I remove adapter +9V, always have a leakage current 4mA to BQ2057W circuit from batteries (VBAT). It makes the remain…
