L7585F Full-Feature, Low-Power SLIC and Switch
Pin Information
(continued)
Table 1. Pin Descriptions
(continued)
Note: On the printed-wiring board (PWB), make the leads to BGND and V
BAT
as wide as possible for thermal and electrical reasons. Also, max-
imize the amount of PWB copper on all leads connected to this device for the lowest operating temperature.

Name/Function
RTI
Ring Lead Test-In.
Test-in relay connects this pin to PR. Connect RTI to the ring lead of
the test-in bus.
Tip Lead Test-In.
Test-in relay connects this pin to PT. Connect TTI to the tip lead of the
test-in bus.
Protected Tip.
The output of the tip driver and input to the transmit current sense circuit.
Connect to the tip of the loop through overvoltage protection.
Tip Lead Ringing Supply.
Ringing relay connects this pin to PT. Connect TRNG to the
ringing supply return.
Bit 5.
B0—B5 determine the state of the SLIC. See Operating States.
Bit 4.
B0—B5 determine the state of the SLIC. See Operating States.
Bit 3.
B0—B5 determine the state of the SLIC. See Operating States.
Bit 2.
B0—B5 determine the state of the SLIC. See Operating States.
Bit 1.
B0—B5 determine the state of the SLIC. See Operating States.
Bit 0.
B0—B5 determine the state of the SLIC. See Operating States.
+5 V Digital dc Supply.
+5 V supply for logic and switch circuitry.
Digital Ground.
Ground return for V
CCD
.
Battery Supply.
Negative high-voltage power supply.
Battery Ground.
Ground return for the battery (V
BAT
) supply.
Tip/Ring Current.
A current output which is proportional to the differential current flowing
from tip to ring. Connect a resistor from this pin to VITR.
Tip/Ring Voltage Output.
The voltage at this output is directly proportional to the differ-
ential tip/ring current. A resistor from this pin to ITR sets the gain.
Transmit ac Input.
Connect a 0.1 μF capacitor from this pin to VITR.
Transmit ac Output Voltage.
The ac voltage at this output is 7.2 times the ac voltage at
pin TXI. The dc voltage is equal to the dc voltage on pin VRTX.
Transmit ac Reference Voltage.
The dc voltage at this output (2.4 V nominal) is the dc
reference for the transmit signal output VTX.
Receive ac Signal Input (Noninverting).
This high-impedance input controls the ac dif-
ferential voltage on tip and ring.
Receive ac Signal Input (Inverting).
This high-impedance input controls the ac differen-
tial voltage on tip and ring.
Analog Ground.
Ground return for V
