9.4 Power Supply Precautions
Always initialize the circuit with NRESET after initiating power supply. The internal circuit state cannot be
guaranteed when switching the HVDD from off to on due to power supply noise and other factors.
CMOS devices may suffer from what is known as “latch-up.” This is a phenomenon in which the PNPN bonds
(thyristor configuration) inside the CMOS IC conduct, resulting in large currents between VDD and VSS and
ultimately damaging the CMOS.
Latch-up occurs when the voltage applied to the input/output pins exceeds rated values, resulting in large currents
within the component, or when the VDD pin voltage exceeds the ratings, causing internal components to yield. If
the voltage exceeds the ratings even momentarily in these cases, a large current will arise between VDD and VSS
once latch-up occurs, resulting in potential overheating and smoke generation. Always observe the following
precautions:
(1) Never raise the input/output pin voltage level above the supply voltage or above the range specified for
electrical characteristics. Avoid lowering below VSS.
(2) Make sure the device is not subject to abnormal noise.
(3) The potential for unused input pins should be pegged to VDD or VSS.
(4) Do not short-circuit the output.
