PROGRAMMABLE OVERVOLTAGE PROTECTION FOR ERICSSON COMPONENTS SUBSCRIBER LINE INTERFACE CIRCUITS, SLICS
description
The TISPPBL1 and TISPPBL2 are dual forward-conducting buffered p-gate
overvoltage protectors. They are designed to protect the Ericsson Components
SLICs (Subscriber Line Interface Circuits) against overvoltages on the
telephone line caused by lightning, a.c. power contact and induction. The
TISPPBLx limits voltages that exceed the SLIC supply rail levels.
The SLIC line driver section is typically powered by a negative voltage, VBat,
in the region of -10 V to -85 V. The protector gate is connected to this
negative supply. This references the protection (clipping) voltage to the
negative supply voltage. As the protection voltage will track the negative
supply voltage the overvoltage stress on the SLIC is minimised. The TISPPBLx
buffered gate design reduces the loading on the SLIC supply during
overvoltages caused by power cross and induction.
Positive overvoltages are clipped to ground by diode forward conduction.
Negative overvoltages are initially clipped close to the SLIC negative supply
rail value. If sufficient current is available from the overvoltage, then the
protector will crowbar into a low voltage ground referenced on-state
condition. As the overvoltage subsides the high holding current of the crowbar
prevents d.c. latchup. The difference between the TISPPBL1 and TISPPBL2 is the
minimum value of holding current. The 105 mA TISPPBL1 can delatch SLIC
programmed line currents up to 55 mA and the 150 mA TISPPBL2 can delatch all
programmed line current values.
These monolithic protection devices are fabricated in ion-implanted planar
vertical power structures for high reliability and in normal system operation
they are virtually transparent. The TISPPBLx is available in 8-pin plastic
small-outline surface mount package and 8-pin plastic dual-in-line package.
