This product is an original Ericsson
product protected by US, European and
other patents.
The TISPPBL2 is a dual forward-
conducting buffered p-gate overvoltage
protector. The protector gate references
the protection (clamping) voltage to
negative supply voltage (i e the battery
voltage, V
). As the protection voltage
will track the negative supply voltage the
overvoltage stress on the SLIC is
minimized.
Positive overvoltages are clamped to
ground by a diode. Negative
overvoltages are initially clamped close
to the SLIC negative supply rail voltage
and the protector will crowbar into a low
voltage on-state condition, by firing an
internal thyristor.
A gate decoupling capacitor, C
GG
, is
needed to carry enough charge to supply
a high enough current to quickly turn on
the thyristor in the protector. C
GG
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 choosen for R
, note that it
is important to always use 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 SLIC.
Power-up Sequence
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.
Analog ground (AGND) should be
connected to battery ground (BGND) on
the PCB in one point.
The capacitors for the battery should
be connected with short wide leads of the
same length.
