STATIC ELECTRICAL CHARACTERISTICS

Table 3. Static Electrical Characteristics

Characteristics noted under conditions of 7.0 V

≤ V

BAT ≤ 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.
