STATIC ELECTRICAL CHARACTERISTICS (continued)

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.
