Texas Instruments bq2058T Lithium Ion Pack Supervisor Datasheet
The bq2058T Lithium Ion Pack Supervisor is designed to control the charge and discharge cell voltage limits for two lithium-ion (Li-Ion) series cells, accommodating battery packs containing series/parallel configurations. The device features low operating current and minimal external components, driving external FET switches to manage battery safety.
The supervisor provides protection against overvoltage, undervoltage, and overcurrent conditions. It monitors individual cell voltages and pack current, disabling charging or discharging paths as necessary. The device includes user-configurable delays for overvoltage, undervoltage, and overcurrent events to prevent false triggering.

Questions answered in these manuals
What is the overvoltage threshold for the standard bq2058T?
The standard version has an overvoltage threshold of 4.25V.
From: Texas Instruments bq2058T Lithium Ion Pack Supervisor Datasheet
What happens when an undervoltage condition is detected?
The DSG output is driven low, disabling the discharge of the pack, and the device enters low-power sleep mode.
