+3V to +5V, 2500VRMS Isolated RS-485/RS-422
Transceivers with ±15kV ESD Protection
product of 9.5V-s. The commercially available trans-
formers for the MAX845 listed in Table 5 meet that
requirement. In most cases, use half of the center-tapped
primary winding with the MAX3535E and leave the other
end of the primary floating. Most of the transformers in
Table 5 are 1:1:1 or 1:1:1:1 turns ratio.
For +3.3V operation (+3.6V maximum) the required pri-
mary ET product is 6.2V-s. All of the previously men-
tioned transformers meet this requirement. Table 6 lists
some other transformers with step-up turns ratios
specifically tailored for +3.3V operation. Most of the
transformers in Table 6 are 1:1:1.3:1.3.
By using a HALO TGM-010 or Midcom 95061 trans-
former, it becomes possible to build a complete isolated
RS-485/RS-422 transceiver with a maximum thickness
less than 0.1in. To minimize power consumption, select
the turns ratio of the transformer to produce the minimum
DC voltage required at VCC2 (+3.13V) under worst-case,
high-temperature, low-VCC1, and full-load conditions. For
light loads on the isolated side, ensure that the voltage at
VCC2 does not exceed +7.5V. For example, the CTX01-
14659 transformer results in 85mA (typ) VCC1 supply cur-
rent with full load on the RS-485 driver. Using a TGM250
1:1:1 transformer lowers the VCC1 supply current to 65mA
(typ), while maintaining good margin on the VCC2 supply.
A slight step-down transformer can result in extra power
savings in some situations. A custom wound sample
transformer with 23 primary turns and 20:20 secondary
turns on a Ferronics 11-050B core operates well with a
VCC1 supply current of 51mA (typ).
