ORDERING INFORMATION
PIN DESCRIPTION
Analog Ground. The voltage to this pin should be mid-way between V
and V .
DD
SS
Positive supply voltage. Typically +5V if a current transformer is used for current sensing.
GND
V

6
Negative supply voltage. Typically 0V if a current transformer is used for current sensing.

Voltage sense inputs. The current into the A/D converter should be set at 14µA
at nominal mains
RMS
voltage. The voltage sense input saturates at an input current of ±25µA peak.
21, 24,

IVN1, IVN2,
IVN3
Inputs for current sensors. The termination resistor voltage from each current transformer is
converted to a current of 16µA
at rated conditions. The current sense input saturates at an input
RMS
current of ±25µA peak.

This pin provides the connection for the reference current setting resistor. A 24kW resistor
connected to V sets the optimum operating condition.
SS
19
VREF
Serial clock output. This output is used to strobe data from the external EEPROM.
8
SCL
Serial data. Send and receive data from an external EEPROM.
9
SDA
Motor pulse outputs. These outputs can be used to drive an impulse counter or stepper motor directly.
11, 12
MON, MOP
Multiplexed phase or direction driver output.
13
Triggers a data reload from the external EEPROM.
7
RLOAD
Multiplexed LED drivers for direction and mains fail indication.
14, 15,

PH1, PH2,
PH3
Calibration LED output. Refer to section Led Output (LED) for the pulse rate output options.
