I am working on getting the Bq20Z95 to charge and gauge correctly. While doing the BQEasy software procedures, I notice a couple of things through SBS1) my measured capacity is at zero even though the...
View ArticleForum Post: RE: How to disable bq24160?
All the versions will start charge if V(BAT) <3.6V. The /CD pin puts the device in HiZ mode, disabling the buck converter, when pulled high. You can add an external PMOS in between the battery and...

bq2057 or bq24031 (with USB input grounded) would provide a linear regulator solution. The most efficient solution would be a step down buck converter like TPS560200 followed by a linear charger like...

The RA0 pin does not actually do anything in the firmware, hence the reason you can't find info on it.

The input capacitor on a buck switching converter is critical to ensure that there is no ringing on at the SW pin the could overvoltage and damage the FETs. The output capacitor is a bit less critical...
View ArticleForum Post: RE: bq24160 / Input current limit
Hi Jeff-san,Their test condition with EVM is 2A fast charge current and resistive 8ohm load at SYS pin to confirm function of input current limit. So the charge current is reduced due to input current...
