Notes:
2. In automotive ans battery operated systems, the power supply lines should be externally protected for load dump and reverse battery. When the V+ and V- Pins are connected to the same
supply voltage source as the device or control line under protection, acurrent limiting resistor should be connectied in series between the external supply and the SP723 supply pins to
limit reverse battery current to within the rated maximum limits. Bypass capacitors of typically 0.01μF or larger from the V+ and V- Pins to ground are recommended.
3. Refer to the Figure 3 graph for determine peak current and dessipation under EOS conditions.
