A circuit for voltage transient protection is provided. The circuit
includes a voltage divider, a low-voltage reset circuit, and an input
transistor. The input transistor receives an input voltage at the source
of the input transistor, and provides a protected input voltage at the
drain of the input transistor. The voltage divider provides a threshold
voltage from the input voltage. The low-voltage reset circuit receives
the threshold voltage. The low-voltage reset circuit causes the gate and
source of the input transistor to short together when the low-voltage
reset circuit is not in a reset state.
