iC-HX
preliminary
3-CHANNEL DIFFERENTIAL COLD LINE DRIVER
Rev A1, Page 1/11
FEATURES
o 6 current-limited and short-circuit-proof push-pull drivers
o Differential 3-channel operation selectable
o Integrated impedance adaption for 30 to 140 Ω lines
o Wide power supply range from 4 to 40 V
o 200 mA output current (at VB = 24 V)
o Low output saturation voltage (< 0.4 V at 30 mA)
o Compatible with TIA/EIA standard RS-422
o Tristate switching of outputs enables use in buses
o Short switching times and high slew rates
o Low static power dissipation
o Dynamic power dissipation reduced with iC-xSwitch
o Schmitt trigger inputs with pull-down resistors, TTL and CMOS
compatible; voltage-proof up to 40 V
o Thermal shutdown with hysteresis
o Error message trigger input TNER
o Open-drain error output NER, active low with excessive chip
temperature and undervoltage at VCC or VB
o Option: Extended temperature range from -40 to 125 °C
APPLICATIONS
o Line drivers for 24 V control
engineering
o Linear scales and encoders
o MR sensor systems
