BQ27426: LDO with REGIN

Part Number: BQ27426
Other Parts Discussed in Thread: BQ27510

 Hi,

two things:

First, a customer is looking for a successor of the BQ27410. It is for a system design. It should have an LDO with REGIN pin. This allows the customer to power the chip while the battery is removed. 

The batteries are VARTA Easypacks, LiIon, single Cell, 1200mAh, 2400mAh.

The BQ27426 does not seem to have this LDO with REGIN pin feature and the BQ274265 is on NRND status.

Second question: what happens when removing a battery and inserting another one. Will the new battery be identified or must the saved saved data be reset?

Thanks

Fred
