ELECTRICAL CHARACTERISTICS
STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics (continued)
Characteristics noted under conditions of 7.0 V ≤ V_BAT ≤ 16 V, -40°C ≤ T_A ≤ 125°C, SLEEP = 5.0 V unless otherwise noted.
Typical values reflect the parameter's approximate midpoint average value with V_BAT = 13 V, T_A = 25°C. All positive currents
are into the pin. All negative currents are out of the pin.
