ISL85003, ISL85003A
Electrical Specifications All parameter limits are established over the Recommended Operating Conditions with TJ = -40°C to +125°C,
and with VIN = 12V unless otherwise noted. Typical values are at TA = +25°C. Boldface limits apply across the operating junction temperature range,
-40°C to +125°C. (Continued)
