ESD PROTECTION
The NCN8024R includes devices to protect the pins
against the ESD spikes voltages. To cope with the different
ESD voltages developed across these pins, the built in
structures have been designed to handle either 2 kV, when
related to the micro controller side, or 8 kV when connected
with the external contacts (HBM model). Practically, the
CRD_RST,
CRD_CLK,
CRD_IO,
CRD_AUX1,
CRD_AUX2, CRD_PRES and CRD_PRES pins can sustain
8 kV. The CRD_VCC pin has the same ESD protection and
can source up to 70 mA continuously, the absolute
maximum current being internally limited with a max at
150 mA. The CRD_VCC current limit depends on VDDP
and CRD_VCC.
