Active production — single-cell Li-Ion charging with USB input
The BQ24078RGTR: It terminates at 4.35V battery pack voltage and delivers up to 1.5A constant charge current, programmable via an external resistor. The 16-VQFN (3x3 mm) exposed pad package with -40°C to 125°C junction temperature range suits compact portable designs and industrial ambient environments.
Protection set and programmable timer for safe charging
Integrated fault protection covers over-temperature, over-voltage, reverse current, and short circuit — the charger enters thermal regulation before junction temperature exceeds the safe limit. The programmable timer provides a backup safety timeout; charge current is also programmable, allowing the designer to trade charge time against thermal budget in the 16-VQFN footprint.
Package and board-fit for thermal management
Surface-mount assembly with Tape & Reel or Cut Tape packaging options; the exposed pad requires a via array under the package for thermal conduction to the inner layers.
ROHS3 compliance and regulatory acceptance
The BQ24078RGTR is ROHS3 compliant, meeting the EU RoHS directive for lead-free and restricted-substance limits.
