PARAMETER
Supply Voltage
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:
High-side voltage measured with respect to ground.
Note 2:
For V
CC
> +13V on the MAX1822, use C1 = C2 = 0.01μF.
Note 3:
Power-Ready Threshold is the voltage with respect to ground at V
OUT
when PR switches high (PR = V
CC
).
Operating Temperature Range ...........................-40°C to +85°C
Storage Temperature Range.............................-65°C to +160°C
