APPLICATION INFORMATION
Supply Voltage Transient
High supply voltage transients can cause a reset output
signal perturbation. For supply voltages greater than 8.0 V
the circuit shows a high immunity of the reset output against
supply transients of more than 100 V/
μ
s. For supply voltages
less than 8.0 V supply transients of more than 0.4 V/
μ
s can
cause a reset signal perturbation. To improve the transient
behavior for supply voltages less than 8.0 V a capacitor at Pin
3 can be used. A capacitor at Pin 3 (C3
≤
1.0
μ
F) reduces
also the output noise.
