Operation
A -12V source is connected to the VBAT_1 input of the LM74610-SQEVM.
shows that the Output
voltage will stay at a constant 0V in this situation. This test simulates the event of connecting a 12V
battery in the reverse direction, and therefore, protects the load from negative voltages.
Figure 4. Response to Start Up Reverse Polarity
Note:
Please note that the leakage current is 60uA (typ). This means that if you apply a voltage on the
output you will see some voltage on input and this voltage will collapse if you draw more current than the
leakage current. The same applies for a reverse voltage applied on the input.
