ELECTRICAL CHARACTERISTICS
(7 V < ASO_RAIL < 18 V, VIN−H = VIN−B w ASO_RAIL, VPP = 5 V, VIN_S3 tied to ASO_RAIL, VBATT_MON = 0 V, EN = 5 V,
IGNIN = 0 V, ISYS = 3 mA (Note 6)) Min/Max values are valid for the temperature range −40°C vTJ v 150 °C unless noted otherwise.
Min/Max values are guaranteed by test, design or statistical correlation.
