Chip power-on reset module, corresponding chip and electronic device

A chip power-on reset module, comprising a power supply state inspection circuit, a signal amplification shaping circuit, an output driving circuit, and a dynamic response enhancement circuit, wherein

• the power supply state inspection circuit is configured to detect a chip power supply, and when a power voltage state is reversed, an analog signal corresponding to a current power supply status is generated;
• the signal amplification shaping circuit is configured to perform hysteretic amplification on the analog signal output by the power supply state inspection circuit, and then shape the amplified signal to output a digital signal;
• the output driving circuit is configured to buffer the digital signal to drive outputting, and generate a power-on reset signal to drive a load;
• and
• the dynamic response enhancement circuit is configured to monitor the power-on reset signal output by the output driving circuit, and lock a state of the power-on reset signal when the power-on reset signal is at a high level, wherein the dynamic response enhancement circuit comprises a first locking circuit and a second locking circuit, the first locking circuit comprises a PMOS transistor (MP0) and a first capacitor (C1), and the second locking circuit comprises an NMOS transistor (MN0) and a second capacitor (C2).
