Product details

Single-cell linear charger in a 6-DSBGA package

It integrates over-temperature, over-voltage, and short-circuit fault protection, so the BOM does not need a separate supervisor IC. The 6-DSBGA package (1.2 mm × 0.8 mm typical) suits space-constrained portable designs — wearable earbuds, medical patches, or compact IoT nodes where every mm² counts.

Charge current and thermal budget

The 250 mA maximum charge current sets the charge-time floor for the cell. For a 100 mAh cell, a full charge at 250 mA takes roughly 30 minutes plus the constant-voltage taper; for a 500 mAh cell, expect about 2 hours.

Frequently asked questions

Where can I buy BQ25100HYFPR and check stock?

BQ25100HYFPR is available to order through independent distribution. Submit a request with your target quantity and preferred delivery window for a firm quotation.

What is the charge current of BQ25100HYFPR?

The maximum charge current is 250 mA, and it is programmable — the actual current is set by an external resistor. The constant-current phase runs until the battery reaches the 4.35 V regulation voltage, then tapers.

BQ25100HYFPR vs BQ25100 – what is the difference?

The BQ25100HYFPR is a specific ordering code variant within the BQ25100 family. The base product number is BQ25100. The 'HYFPR' suffix denotes the 6-DSBGA package and the Tape & Reel / Cut Tape packaging options. Electrically, the charge current, voltage, and protection features are identical across the family. The difference is purely in the package and reel format.
