Do you expect longer battery life from new portable devices than you did five years ago?
STMicroelectronics has released the L9962, an integrated circuit designed for managing lithium-ion and lithium-polymer battery packs. The device provides monitoring capabilities for up to 10 series-connected cells.
Why it matters
By integrating battery-pack management functions onto a single chip, this component reduces the count of external hardware required for power distribution systems. This consolidation simplifies circuit design for engineers managing compact battery stacks.
The L9962 maintains 0.25% current-measurement accuracy and supports 70mA of cell-balancing current. Housed in a 7mm x 7mm 48-pin TQFP, it includes a 3.3V low-dropout regulator and draws as little as 2µA in deep-sleep mode.
The players
STMicroelectronics
A global semiconductor firm that designs and manufactures integrated circuits and power management components for automotive and industrial markets.
The details
The device operates by measuring individual cell voltages on a continuous cycle using a programmable loop time, which is managed by an integrated ADC (analog-to-digital converter). An I2C interface—a serial communication bus used to connect integrated circuits—allows host systems to configure operational parameters and extract battery state-of-charge data.
Timeline
The L9962 battery management IC was released on October 14, 2026.
The Tech Race
The release of the L9962 follows the ongoing industry push toward highly integrated battery management systems that minimize board footprint. This device competes within a crowded sector where power efficiency and external component reduction remain the primary performance benchmarks.
This component is primarily relevant for design engineers building battery-powered electronics that require precise cell monitoring and longevity. The chip provides a pathway to extend battery runtime through power-saving modes, with availability now for high-volume manufacturing.
The takeaway
This IC reduces the hardware overhead required to manage multi-cell battery packs, simplifying the architecture for modern portable electronics. Engineers should monitor STMicroelectronics product documentation for specific integration guides and future firmware-compatible development boards.
