FUNCTIONAL DESCRIPTION
All data given in this chapter are typical values, except
when otherwise specified.
Supplies
LINE INTERFACE AND INTERNAL SUPPLY (PINS LN, SLPE,
REG AND VBB)
The supply for the TEA1099H and its peripherals is
obtained from the line. The IC generates a stabilized
reference voltage (Vref) between pins SLPE and GND.
This reference voltage is equal to 3.7 V for line currents
lower than 18 mA. It than increases linearly with the line
current and reaches the value of 6.1 V for line currents
higher than 45 mA. For line currents below 9 mA, the
internal reference voltage generating Vref is automatically
adjusted to a lower value. This is the so-called low voltage
area and the TEA1099H has limited performances in this
area (see Section “Low voltage behaviour”). This
reference voltage is temperature compensated.
The voltage between pins SLPE and REG is used by the
internal regulator to generate the stabilized reference
voltage and is decoupled by means of a capacitor between
pins LN and REG. This capacitor converted into an
equivalent inductance realizes the set impedance
conversion from its DC value (RSLPE) to its AC value (done
by an external impedance).
The IC regulates the line voltage at pin LN and it can be
calculated as follows:

ISLPE = Iline – Ix
where:
Iline = line current
Ix = current consumed on pin LN (approximately a few µA)
ISLPE = current flowing through the RSLPE resistor
