... Information”). The threshold voltage is typically set at 4V, with a tolerance of about ±5%. If the supply voltage falls below this threshold, the MCP3905A/05L/06A devices will be held in a Reset condition (equivalent to applying logic ‘0’ on the MCLR pin). The typical hysteresis value is approximately 200 mV in order to prevent glitches on the power supply ...

... DTF converter. 4.6 Low-Pass Filter and DTF Converter The MCP3905A/05L/06A low-pass filter is a first-order IIR filter that extracts the active real-power information (DC component) from the instantaneous power signal. The magnitude response of this filter is detailed in Figure 4-5. Due to the fact that the instantaneous power signal has harmonic content (coming from the 2ω ...

... MINIMAL OUTPUT FREQUENCY FOR NO-LOAD THRESHOLD The MCP3905A/05L/06A devices also include, on each output frequency, a no-load threshold circuit that will eliminate any creep effects in the meter. The outputs will not show any pulse if the output frequency falls below the no-load threshold. The minimum output × ...
