ELECTRICAL CHARACTERISTICS

MAXIMUM RATINGS

POWER DISSIPATION

During operation, the temperature of the die must not exceed the maximum junction temperature. Depending on the operating

ambient temperature and the total internal dissipation this limit can be exceeded.

To optimize the thermal management scheme and avoid overheating, the 900844 provides a thermal management system

that protects against overheating. This protection should be considered as a fail-safe mechanism, and the application design

should initiate thermal shutdown under normal conditions. Reference Thermal Management for more details.

POWER CONSUMPTION

Table 2 defines the maximum power consumption specifications in the various system and device states. For each entry in

the table, the component is assumed to be configured for driving purely capacitive loads, and the voltages listed in each entry

are nominal output voltages.

Note that the “Soft Mechanical Off” state is a transitional state. The device will spend less than 150 µs in this state before V15

starts to turn on, upon detection of a valid input voltage.
