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 V
BAT = 13 V, TA = 25°C. All positive currents
are into the pin. All negative currents are out of the pin.
