Product details

For new designs or BOM lines requiring a current-production part, a replacement should be identified.

Single-cell Li-ion linear charger in 20-HTSSOP

The BQ24001PWPR is a linear charger IC for single-cell Lithium-Ion battery packs, delivering a constant charge current up to 1.2 A with a regulated battery voltage of 4.2 V. Programmable features include charge current and timer settings. The device includes over-temperature fault protection and operates over a -40°C to 70°C ambient temperature range.

The maximum supply voltage is 10 V, so the input rail must be regulated to stay within that absolute-maximum rating.
