7 / 16 page Analog Integrated Circuit Device Data Freescale Semiconductor 7 33990 ELECTRICAL CHARACTERISTICS DYNAMIC ELECTRICAL CHARACTERISTICS 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.
