bq7790x Stackable Li-Ion Battery Protector ICs

Texas Instruments bq7790x 3-to-5 Series Stackable Li-Ion Battery Protector ICs are low-power battery pack protectors that implement a suite of voltage, current, and temperature protections. These protections are all done without microcontroller (MCU) control. Protection thresholds and delays are factory-programmed and available in a variety of configurations. Separate over temperature and under temperature thresholds for discharge (OTD and UTD) and charge (OTC and UTC) are provided for added flexibility. The Texas Instruments bq7790x achieve pack protection via the integrated independent CHG and DSG low-side NMOS FET drivers, which may be disabled via two control pins.
