3 Description

The BQ77207 family of products provides a range

of voltage and temperature monitoring including

overvoltage (OVP), undervoltage (UVP), open wire

(OW), and overtemperature (OT) protection for Liion

battery pack systems. Each cell is monitored

independently for overvoltage, undervoltage, and

open-wire conditions. With the addition of an external

NTC or PTC thermistor, the device can detect

overtemperature conditions.

In the BQ77207 device, an internal delay timer

is initiated upon detection of an overvoltage,

undervoltage, open-wire, or overtemperature

condition. Upon expiration of the delay timer, the

respective output is triggered into its active state

(either high or low, depending on the configuration).

The overvoltage triggers the COUT pin if a fault is

detected, and undervoltage triggers the DOUT pin if a

fault is detected. If an overtemperature or open-wire

fault is detected, then both the DOUT and COUT

will be triggered. For quicker production-line testing,

the BQ77207 device provides a Customer Test Mode

(CTM) with greatly reduced delay time.
