Battery Protection, Authentication & Identification Solutions

A battery is constructed from a string of series and parallel cells. Each series cell; or group of paralleled cells require protection from overcharge, over discharge and short circuit conditions. TI’s Lithium-Ion protection family of devices offer this protection with the BiCMOS process, different voltage thresholds, sleep current consumption of less than 3.5µA, 50 mV precision internally trimmed thresholds and short-circuit protection.

Use the parametric search table to find Lithium-Ion protection parts, download datasheets and application notes, and order samples or evaluation modules.
