EMC CHARACTERISTICS (Cont’d)
12.7.2 Absolute Electrical Sensitivity
Based on three different tests (ESD, LU and DLU)
using specific measurement methods, the product
is stressed in order to determine its performance in
terms of electrical sensitivity. For more details, re-
fer to the AN1181 ST7 application note.
12.7.2.1 Electro-Static Discharge (ESD)
Electro-Static Discharges (3 positive then 3 nega-
tive pulses separated by 1 second) are applied to
the pins of each sample according to each pin
combination. The sample size depends of the
number of supply pins of the device (3 parts*(n+1)
supply pin). Two models are usually simulated:
Human Body Model and Machine Model. This test
conforms to the JESD22-A114A/A115A standard.
See Figure 75 and the following test sequences.
Human Body Model Test Sequence
–CL is loaded through S1 by the HV pulse gener-
ator.
– S1 switches position from generator to R.
– A discharge from CL through R (body resistance)
to the ST7 occurs.
– S2 must be closed 10 to 100ms after the pulse
delivery period to ensure the ST7 is not left in
charge state. S2 must be opened at least 10ms
prior to the delivery of the next pulse.
Machine Model Test Sequence
–CL is loaded through S1 by the HV pulse gener-
ator.
– S1 switches position from generator to ST7.
– A discharge from CL to the ST7 occurs.
– S2 must be closed 10 to 100ms after the pulse
delivery period to ensure the ST7 is not left in
charge state. S2 must be opened at least 10ms
prior to the delivery of the next pulse.
– R (machine resistance), in series with S2, en-
sures a slow discharge of the ST7.
