Battery Management IC for Portable Devices

The YINGHUA BQ27441DRZR-G1B is a battery management semiconductor in a SON-12 package. It provides fuel-gauge and protection functions for single-cell lithium-ion packs in compact electronics. Designers working on space-constrained products such as wearables, IoT sensors or handheld instruments will find the 12-pin outline suits dense board layouts.

Integration Limits of the SON-12 Package

The 12-lead SON footprint restricts the number of external connections available for thermistors, communication lines or additional safety circuitry. Engineers needing multi-cell monitoring, high-current path integration or a larger pin count for complex system interfaces must select a different package or controller. The device is not suited for applications that demand more than the provided 12 terminals.

Questions about this item

What does the SON-12 package mean for board layout?

The SON-12 package uses 12 pins in a compact outline, so the PCB footprint is small and suits space-constrained battery packs.

How does the BQ27441 fuel gauge report capacity in a real system?

It measures voltage, current and temperature to calculate remaining charge and state-of-health, then communicates the data over its I²C interface to the host controller.
