BQ24232: Does a CEn toggle resets Precharge and Fast-Charge timers?

Part Number: BQ24232

Hi there,

We have a design where we use a BQ24232 but with a battery capacity ~5Ah, that we only charge with 0.5A, so it takes us over 10h to charge from empty. 

Currently we have the timers enabled on the PCB, which means the Fast Charge gets terminated after ~6h, before the battery is full. 

Can you confirm that toggling the CEn input of the chip (i.e. having it go high and then low again) should reset the Timers? 

We have a Fuel Gage (BQ27426YZFR) as welll in the design - so from safety perspective we can check that the charge is happening OK and we will stop toggling CEn when the battery is full. 

Thanks for your help,

Mickael
