Abstract
A reset circuit for resetting and terminating the resetting of a reset target includes an n-channel metal-oxide-semiconductor field-effect transistor (MOSFET), a gate drive circuit configured to switch a drain voltage of the n-channel MOSFET from a low level to a high level when a power supply voltage exceeds a predetermined threshold, a sink circuit configured to maintain the drain voltage at the low level by sinking a current flowing from a drain side of the n-channel MOSFET to the sink circuit, and a block circuit configured to block the current sinking to the sink circuit when the power supply voltage exceeds the predetermined threshold. The low level indicates a state where the reset target is in a reset state and the high level indicates a state where the reset state of the reset target is terminated.
