3.1 POWER SUPPLY REQUIREMENTS


Minimum supply voltage

8V continuous

Cranking dropouts

Able to survive 0V for 50mS providing the supply was at least 10V
before the dropout and recovers to 5V afterwards.

Maximum supply voltage

35V continuous (60V protection)

Reverse polarity protection

-35V continuous

Maximum operating current

30mA at 24V
