BQ24262 / Battery discharge current in HIZ mode

Other Parts Discussed in Thread: BQ24620EVM

Hi,

Please let me ask about battery discharge current in HIZ mode.

I know that the IBAT_HIZ is specified in Electrical Characteristics, then I'd like to know if IBAT_HIZ is varied depend on register setting or pin setting. Now I'm asking at HIZ mode at VIN = 0 V.

We do not expect a difference in IBAT_HIZ whether your use register or pin to enter HIZ mode.

Hi Jeff,

Today I tried to reproduce what customer is asking. I could reproduce it by using bq24620EVM as attached (I just have only bq24620EVM). It may be latched up due to external noise into SCL/SDA.

Can you also reproduce this on your bench, and give your idea to work around, for example filtering noise into SCL/SDA. This behavior can be seen in customer board also, so I need solution to resolve this behavior.
