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.
