PWM Protocol

The output has been designed as a two-wire current interface based on a Pulse Width Modulation principle.

Each zero crossing of the magnetic input signal triggers an output pulse indicated by IHigh and ILow current

consumption.

The PWM Protocol is available in two different protocol options: standard TLE5046iC-PWM2 and TLE5046iC-

PWM2E with indication of internal errors by using the warning pulse.

The timing characteristic for TLE5046iC-PWM2 and TLE5046iC-PWM2E is given in the table below:
