Applications Information
Extended ESD Protection
ESD protection structures are incorporated on all pins
to protect against electrostatic discharges up to ±2kV
(HBM) encountered during handling and assembly.
COM1 and COM2 are further protected against ESD
up to ±15kV (HBM) without damage. The ESD struc-
tures withstand high ESD both in normal operation and
when the device is powered down. After an ESD event,
the MAX14535E
MAX14539E continue to function with-
out latchup.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.
Human Body Model
Figure 3a shows the Human Body Model. Figure 3b shows
the current waveform it generates when discharged into
a low impedance. This model consists of a 100pF capaci-
tor charged to the ESD voltage of interest that is then
discharged into the device through a 1.5k
resistor.
IEC 61000-4-2
The main difference between tests done using the
Human Body Model and IEC 61000-4-2 is higher peak
current in the IEC 61000-4-2. Because series resistance
is lower in the IEC 61000-4-2 ESD test model (Figure
3c) the ESD withstand voltage measured using the
Human Body Model. Figure 3d shows the current wave-
form for the ±8kV IEC 61000-4-2 Level 4 ESD Contact
Discharge test.
The Air-Gap Discharge test involves approaching the
device with a charged probe. The Contact Discharge
method connects the probe to the device before the
probe is energized.
