The Texas Instruments BQ7790522PW is a battery protection IC designed for 3 to 5 series-connected Lithium Ion cells. It integrates overcurrent, over/under voltage, short-circuit, and overtemperature fault protection into a single 20-TSSOP package.
The Tube shipping medium is typical for prototype and low-to-medium volume assembly; for higher volumes the part is also available in Tape & Reel under a different order code.
It supports 3 to 5 series-connected Lithium Ion cells.
Yes, it includes overcurrent protection as one of its integrated fault protections, along with over/under voltage, short-circuit, and overtemperature.
Typical applications include portable power tools, e-bikes, energy storage systems, and any multi-cell Li-Ion battery pack requiring integrated overcurrent, voltage, and temperature fault protection.
