Claim 2:
3. The device of claim 2, wherein the first protection circuit further comprises
a first noise filter circuit connected between the first pad and the second pad on the output side of the timer circuit and on an input side of the voltage detection circuit and configured to invert a logic of the control signal while suppressing an error of the control signal due to power supply noise,
a first buffer circuit connected between the first pad and the second pad on an output side of the first noise filter circuit and on the input side of the voltage detection circuit and configured to invert a logic of an output signal of the first noise filter circuit and amplify the output signal of the first noise filter circuit, and
a second noise filter circuit connected to an output side of the first buffer circuit and the input side of the voltage detection circuit and configured to suppress an error of an output signal of the first buffer circuit due to the power supply noise.
