Key Features
- Fixed overvoltage threshold eliminates external resistor trimming for reliable 2S and 3S Li-Ion pack protection
- Single-channel 6-pin SON package minimizes PCB footprint in compact battery management circuits
- Dedicated input fault protection controller prevents cell damage from overcharge conditions automatically
- Plastic/epoxy SON-6 package supports standard SMT reflow assembly for high-volume battery pack production
Applications
The BQ294515DRVT protects 2-series and 3-series Li-Ion battery packs in portable consumer electronics such as power tools, laptops, and handheld devices by cutting off charging when any cell exceeds the overvoltage threshold. It is used in compact battery management systems where a dedicated single-channel protection IC occupies less space than a full BMS with balancing. E-bike battery packs and portable medical devices with multi-cell Li-Ion configurations also benefit from its fixed-threshold overvoltage detection and automatic pack disconnect.

Frequently Asked Questions
For which Li-Ion cell configurations is the BQ294515DRVT specifically designed to provide overvoltage protection?
The BQ294515DRVT is designed specifically for 2-series (2S) and 3-series (3S) Li-Ion battery packs. These configurations produce pack voltages of approximately 8.4 V fully charged for 2S and 12.6 V for 3S packs. The fixed overvoltage threshold is factory-trimmed to match the per-cell maximum voltage limit of Li-Ion chemistry without requiring external resistor adjustment.
How does the BQ294515DRVT's fixed threshold differ from an adjustable overvoltage protector in 2S Li-Ion pack designs?
Unlike adjustable overvoltage protection controllers that use 2 or more external resistors to set the trip voltage, the BQ294515DRVT uses a fixed factory-set threshold, reducing BOM count by 2 components and eliminating resistor tolerance errors. This simplifies the PCB layout and cuts calibration cost in high-volume 2S or 3S Li-Ion pack production lines where threshold accuracy is pre-guaranteed by the manufacturer.
How does the 6-pin SON package of BQ294515DRVT benefit space-constrained battery management board designs?
The BQ294515DRVT uses a 6-pin SON (S-PDSO-N6) package with approximately 0.08 mm pitch and a square body of roughly 1.6 mm × 1.6 mm. This ultra-compact footprint allows placement inside slim battery cell assemblies and portable device battery boards where only a few square millimeters are available for the protection circuit alongside the FET switches.
What happens to the Li-Ion pack circuit when BQ294515DRVT detects an overvoltage condition?
When the monitored cell voltage exceeds the BQ294515DRVT's fixed overvoltage threshold, the device drives its output pin to control an external protection FET, disconnecting the charger path and stopping current flow into the 2S or 3S pack. This prevents cells from exceeding their maximum voltage (typically 4.2 V to 4.35 V per cell), which would cause electrolyte decomposition, capacity loss, or thermal runaway in Li-Ion chemistry.
