The BQ7790512PWR from Texas Instruments is an ultra-low-power stackable battery protector IC suitable for 3 to 5 series Lithium-Ion and Li-Phosphate battery packs. It provides a full suite of voltage, current, and temperature protections without requiring a microcontroller.
Key electrical specifications include voltage protection with an accuracy of ±10 mV, overvoltage protection ranging from 3 V to 4.575 V, and undervoltage protection from 1.2 V to 3 V. Current protection is offered with various thresholds for overcurrent discharge, overcurrent discharge 2, and short circuit discharge. Temperature protection includes overtemperature and undertemperature thresholds for both charging and discharging states.
This device operates within a temperature range of -40°C to 85°C. It features independent charge (CHG) and discharge (DSG) FET drivers and has a 36-V absolute maximum rating per cell input. The IC also includes built-in self-test functions for high reliability and a low shutdown mode current consumption of 0.5 µA maximum.
The BQ7790512PWR is supplied in a 20-TSSOP (0.173", 4.40mm Width) surface-mount package. It is delivered in a large tape and reel format with a package quantity of 2000 units.
