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
