Key Features
- Single-channel input fault protection with integrated gate-drive output, blocking reverse-polarity and overvoltage events up to 28 V without an external microcontroller
- Ultra-compact 6-pin WSON (1.5 mm × 1.5 mm) footprint enables fault protection in space-constrained portable and wearable designs
- JESD-609 Code e4 (RoHS-compliant, Pb-free) with low quiescent current path, minimising standby power loss in battery-powered systems
Applications
The BQ294515DRVR is designed for protecting lithium-ion battery packs and DC power-supply inputs in portable electronics, power tools, and industrial handheld devices where reverse-polarity and overvoltage faults can damage downstream circuitry. Its compact WSON package and single-component protection path make it suitable for space-constrained PCB designs in medical wearables and IoT sensor nodes that require reliable input fault protection without additional controller firmware.

Frequently Asked Questions
What voltage range does the BQ294515DRVR protect against, and how is the overvoltage threshold set?
The BQ294515DRVR protects input rails from overvoltage events up to 28 V. The device uses an internal fixed-threshold comparator that drives an external MOSFET gate to disconnect the load when the input exceeds the rated limit, providing automatic protection without requiring microcontroller intervention or external resistor dividers in typical single-cell Li-ion battery pack designs.
How does the 6-pin WSON package of the BQ294515DRVR benefit compact PCB layouts?
The 6-pin WSON package measures approximately 1.5 mm × 1.5 mm with a 0.8 mm pitch, enabling fault-protection circuitry in PCB areas smaller than 4 mm². This is critical for wearable devices and IoT nodes where board space is limited, allowing the BQ294515DRVR to fit alongside a battery connector with minimal routing compared to SOT-23 or SO-8 alternatives.
In which battery protection topologies can BQ294515DRVR replace a discrete MOSFET-and-comparator solution?
The BQ294515DRVR integrates fault detection and gate-drive logic for 1-cell Li-ion packs operating at 2.5 V to 4.2 V nominal, replacing a standalone comparator IC plus discrete resistors and a P-channel MOSFET. This single-chip approach reduces BOM count by at least 3 components and shortens design time for reverse-polarity protection in USB-C power-delivery input stages and portable medical instruments.
