Voltages relative to V SS .
Does not include current through V CH , R T , and DIV pins.
Below this voltage no I/O pins are active.
Does not include tolerance of R T resistor.
V BIAS and resistor tolerances must be added to determine actual threshold.
Specified temperature thresholds are only valid if recommended thermistor types are used.
Specification is guaranteed by design.

Mode Select. Connect to V SS for linear mode of operation or C BIAS for comparator
mode of operation.
Thermistor Divider. Stable output to form a resistor divider for measuring
temperature on THM
Positive Current Sense. Connect to the charge source side of the sense resistor
Negative Current Sense. Connect to the cell stack side of the sense resistor
Chip Supply Input: +4.5V to +16.5V range
Failsafe Timeout. Timeout is selected by an external resistor from R T to V SS
Thermistor Input. Connect to a thermistor located in the cell pack and a divider
resistor from the Div pin
Battery Voltage Sense Input. Connect to a divider from the positive terminal of the
cell stack to measure the voltage of a single cell
