protector will crowbar into a low voltage
on-state condition, by firing an internal
thyristor.
A gate decoupling capacitor, C
, is
needed to carry enough charge to supply
a high enough current to quickly turn on
the thyristor in the protector. C
shall
be placed close to the overvoltage
protection device. Without the capacitor
even the low inductance in the track to
the V
supply will limit the current and
delay the activation of the thyristor
clamp.
The fuse resistors R
serve the dual
purposes of being non-destructive
energy dissipators, when transients are
clamped and of being fuses, when the
line is exposed to a power cross.
If a PTC is chosen for R
, note that it is
important to always use the PTC′s in
series with resistors not sensitive to
temperature, as the PTC will act as a
capacitance for fast transients and
therefore will not protect the TISP.
No special power-up sequence is
necessary except that ground has to be
present before all power supply voltages.
Printed Circuit Board Layout
Care in PCB layout is essential for
proper function. The components
connecting to the RSN input should be
placed in close proximity to that pin, so
that no interference is injected into the
RSN pin. Ground plane surrounding the
RSN pin is advisable.
The two ground pins AGND and BGND
should be connected together on the
PCB at the device location.
The capacitors for the battery should
be connected with short wide leads of the
same length.
