are at V
Note 1: The sense trip levels are determined by an internal resistor divider network that provides a typical difference of 30mV from
Note 2: Typical variations of Negative Delta Voltage and Thermistor Input Resolution parameters are less than ±4mV.
Note 3: Ratio of actual versus expected timeout (see Table 4). Tested with TM1 = TM2 = floating.
Note 4: To recognize a battery insert signal, V
