MON, MOP
Motor pulse outputs. These outputs are used to driver in impulse counter or a stepper
motor. They can also be used for reactive energy pulses LED indicator, or for output
Σ
signal of analog current/voltage channel respectively, or for test mode i/o
Σ
signal for
analog current/ voltage channel respectively
Chip select - data transmission enable: a falling edge in this pin places the device in
communication mode. Bringing SCS high places the serial bus in high impedance
Output of internal LowDrop regulator and power supply for digital core
Ground: this pin provides a supply return and analog signal reference level.
Positive Power Supply. Typically +5V
Power for programming OTP cells
Output of internal LowDrop regulator and power supply for analog core and OTP cells
Analog input: +and – current (respectively) channel 1
Analog input: +and – current (respectively) channel 2
Analog input: +and – voltage (respectively) intended for use with the voltage transducer
Select data in or data out on SDA or Measurement latching for transmission or output
for negative power
Input of internal crystal oscillator or input for external measure clock or current setting
input for internal RC oscillator
Output of internal RC or crystal oscillator
Serial clock input for the synchronous serial interface or for No Load Condition Led
indicator
Serial Data. Send and receiver data synchronous within CLK, or Tamper Detected Led
indicator
Signal for active energy pulses LED indicator or signal of analog current channel
multiplex (available only when used as peripheral and if
