Supply Voltage
The T2117 contains voltage limiting and can be con-
nected with the mains supply via the diode D1 and the
resistor R1. Supply voltage between Pin 5 and 7 is limited
to a typical value of 9.5 V.
The series resistance R1 can be calculated (figures 7
and 8) as follows:
R1max = 0.85
VMmin – VSmax
2 Itot
; P(R1) =
(VM – VS)2
2 R1
Itot
= IS + IP + Ix
whereby:
VM
= Mains voltage
VS
= Limiting voltage of the IC
Itot
= Total current consumption
IS
= Current requirement of the IC (without load)
Ix
= Current requirement of other peripheral
components
P(R1) = Power dissipation at R1
