SUPPLY VOLTAGES AND SYSTEM SPECIFICATION ELECTRICAL CHARACTERISTICS (7 V < ASO_RAIL < 18 V, VIN−H

= VIN−B w ASO_RAIL, VPP = 3.3 V, VIN_S3 tied to ASO_RAIL, VBATT_MON = 0 V, IGNIN = 0 V, ISYS = 3 mA (Note 6))

Minimum/Maximum values are valid for the temperature range −40°C v TJ v 150°C unless noted otherwise. Min/Max values are

guaranteed by test, design or statistical correlation.
