• † Notice: Stresses above those listed under 'Absolute Maximum Ratings' may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other con -ditions above those indicated in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended periods may affect device reliability. Specifications are for pack -aged product only.

• ‡ Notice: The device is not guaranteed to function outside its operating ratings.

Note 1: Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5 kΩ in series with 100 pF.

TABLE 1-1: ELECTRICAL CHARACTERISTICS

Electrical Characteristics: V DD = V HB = 12V; V SS = V HS = 0V; No load on LO or HO; T A = +25°C; unless otherwise noted. Bold values indicate -40°C ≤ T J ≤ +125°C. Note 1

Total power dissipation in the MIC4604 is equal to the power dissipation caused by driving the external MOSFETs, the supply current and the internal bootstrap diode.
