LTC6802-1
OPERATION
POWER DISSIPATION AND THERMAL SHUTDOWN
The MOSFETs connected to the pins S1 through S12 can be
used to discharge battery cells. An external resistor should
be used to limit the power dissipated by the MOSFETs. The
maximum power dissipation in the MOSFETs is limited by
the amount of heat that can be tolerated by the LTC6802-1.
Excessive heat results in elevated die temperatures. The
electrical characteristics are guaranteed for die tempera-
tures up to 85°C. Little or no degradation will be observed
in the measurement accuracy for die temperatures up
to 105°C. Damage may occur near 150°C, therefore the
recommended maximum die temperature is 125°C.
To protect the LTC6802-1 from damage due to overheating,
a thermal shutdown circuit is included. Overheating of the
device can occur when dissipating significant power in the
cell discharge switches or when communicating frequently
to the device using the current-mode serial interface. The
problem is exacerbated when operating with a large volt-
age between V + and V – or when the thermal conductivity
of the system is poor.
If the temperature detected on the device goes above ap-
proximately 145°C, the configuration registers will be reset
to default states, turning off all discharge switches and
disabling A/D conversions. When a thermal shutdown has
occurred, the THSD bit in the temperature register group
will go high. The bit is cleared by performing a read of the
temperature registers (RDTMP command).
Since thermal shutdown interrupts normal operation, the
internal temperature monitor should be used to determine
when the device temperature is approaching unacceptable
levels.
