Line driver recycles power
Reusing electrical energy stored on the output lines can reduce the power dissipation by up to 50%, which allows the designer to increase packaging density on the PCB board.
iC-Haus' iC-HX line driver is pin compatible with the iC-DL, but an additional operating mode allows it to reuse electrical energy stored on the output lines Depending on cable length and impedance, this mode reduces the power dissipation by up to 50%, which allows the designer to increase packaging density on the PCB board

Compact angle encoder offers flexible operation
The iC-MA is a general-purpose magnetic angle encoder in a space-saving DFN10 package.
With output resistance in the range of 30 to 140ohm, the iC-HX is adapted to usual cable impedance and permits trouble-free transmission of signals without ringing effects.
Drivers can be paired for three-channel differential operation.
The push-pull output stages can cope with a high driver power of typically 300mA from 24V.
They are also current-limited and short-circuit-proof, shutting down with excessive temperature.
For bus applications the output stages can be switched to high impedance using input ENA.
iC-HX monitors supply voltages VB and VCC and also the chip temperature, switching all output stages to high impedance in the event of error.
The open-drain output NERR, which is also short-circuit-proof, signals errors via the connected line and can be linked up to the message outputs of other ICs via input TNER to generate system error messages.
All inputs are CMOS and TTL-compatible and protected against ESD.
The 5 x 5mm2 QFN28 package with its integrated thermal pad enables iC-HX to operate in a temperature range of -40 to +125C.
