Application information
Supply voltage transients
High supply voltage transients can cause a reset output signal disturbance.
For supply voltage greater than 8 V the circuit shows a high immunity of the reset output
against supply transients of more than 100 V/ms. For supply voltage lower than 8 V, supply
transients of more than 0.4 V/ms. can cause a reset signal disturbance.
