DYNAMIC ELECTRICAL CHARACTERISTICS
Table 5. Dynamic Electrical Characteristics
Characteristics noted under conditions of 7.0 V ≤ VBAT ≤ 16 V, -40°C ≤ TA ≤ 125°C, SLEEP = 5.0 V unless otherwise noted.
Typical values reflect the parameter's approximate midpoint average value with VBAT = 13 V, TA = 25°C. All positive currents
are into the pin. All negative currents are out of the pin.
