BQ25100: BQ25100HYFPR

Part Number: BQ25100
Other Parts Discussed in Thread: BQ25101, , BQ25180

Tool/software:

Hi Team,

Our customer "Mesi Medical" is working on a thermometer module where on the power side they are using 

  • BQ25100HYFPR charger for battery.
  • BQ27427YZF battery gauge placed between the charger and battery.
  • BQ298015RUGR Battery protection.
  • TPS62743YFPR buck converter.
  • LP5812AYBHR LED driver.

They had a question regarding the BQ25100HYFPR.  

- Is there any option to have both CHG status and PRE-TERM pin? Basically the same charger in larger BGA package that combines functionality of BQ25100 and BQ25101.

- The charger is tied to battery, which powers the system (LED driver and buck converter). Sometimes it happens that charger gets stuck in pre-charge state because system sucks up all the power. We increased pre-charge current which reduced likelihood of this stuck state but it did not completely solve it.

Thanks in advance.

Best regards,

Ahmad
