FN4920.4
Access High Voltage Switch
The ISL5571A is a solid state device designed to replace the
electromechanical relay used on Subscriber Line Cards. The
device contains two Line Break MOSFET switches, one Ring
Return MOSFET switch and one Ring Access SCR switch.
The ISL5571A is pin-for-pin compatible with the Lucent
L7581AAE LCAS and Clare CPCL7581A Products.
Improvements include: line break switches rON match (0.5
Max) higher dV/dt sensitivity (5000V/µs), protection SCR
hold current set to 110mA.
The line break MOSFETs have very low on resistance
(<16.0Typ) and Ron match (<0.05Typ, 0.5Max) and a
blocking voltage >330V. The Ring Return MOSFET has a
typical Ron of 50and a blocking voltage >330V. The
Ringing Access switch is implemented with a SCR device
with a blocking voltage >480V. The SCR switch inherently
offers low EMI connect and disconnect circuitry. All control
I/Os use TTL thresholds making the device compatible with
3V logic.
The ISL5571A also includes on-chip protection in the form of
an over-voltage clamping circuit, current-limited MOSFET
switches, and thermal shutdown circuitry. The over-voltage
clamping circuit consists of a diode bridge and SCR.
