Thermal Shutdown
is fully de−activated and neither the torch/video, nor the
flash can be launched. The rest of the chip is maintained
active in order to keep a full control of the operation, in
particular the SuperCAP bias voltage is active and
regulated.
diode based clamp structure can be wired to sustain the ESD specifications as depicted in Figure 25.
When the thermal shutdown is engaged, the charge pump
Different structures might apply to protect specific pins, in particular the power related functions. In this case, a single

Basic I/O Protection Structure
built in diode structure as depicted in Figure 24. Since a
diode is attached between the I/O pin and the supply pin,
the voltage at the I/O pin shall not extend the V
plus one Vf drop.
All the pins of the NCP5680 device are ESD protected by
