Figure 20-1. Example in External protection Input

Note: 1. To ensure that the FET switch ON time is as expected, the chip should remain in Active/Idle

mode during this time period. Alternatively, SW may switch off the FETs while External Pro-

tection Input is active, and re-enable FETs on next INT1 interrupt. In this case, SW may

enter Power-save without considering the switch ON time of the FETs.
