Stacked Overvoltage Battery Protector Reference Design
Description
The secondary level protectors for 48V-60V battery systems are being mandated in industrial applications. The TIDA-00108 reference design introduces the user to implement a robust stacked architecture: without compromising high accuracy voltage detection system for a 10s-15s series rechargeable cells. In the bq7718xy family: each cell is monitored independently with an embedded delay timer provided to prevent false trips of the in-line fuses
Features
- Architecture allows 2-3 bq7718xy to be stacked to implement 10s-15s secondary protector active circuitry with fuse in small foot-print enables inclusion inside of the battery packSecondary protector solution can also coexist with the bq76920/30/40 first-level pmonitor and protector
Applications
- Fitness machine
- Battery energy storage system
- Other industrial battery pack (>=10S)
- Battery pack: cordless power tool
- Battery pack: vacuum cleaner/robot
- Other industrial battery pack (1S-9S)
