BQ24450: Replacement linear lead-acid charger

Glen Spence

Part Number: BQ24450
Other Parts Discussed in Thread: UC2906, UC3906, BQ24650

I'm using the BQ24450 in a new design, but it is listed as NRND. Is there a replacement for this part? Is the lifetime 10 years?

The bq24450 is a very old device much older that data sheet indicates.
But no plans to End of Life the bq24450 similar device UC2906 / UC3906 are still available long after they have been NRND.

A better device is the bq24650, see application report SLVA437A.
