Innosilicon Power-On-Reset (POR) circuit provides reliable reset function for general applications.
The POR circuit is powered by 1.8V analog supply and monitors 0.8V~1.0V digital supply. It generates POR_OUT signal to reset the digital logic. The POR signal is set low if analog supply or digital supply is below the threshold voltage, and will be set high if both of analog supply and digital supply exceed the threshold voltage.
