Power/Energy Metering IC with Pulse Output
SA2007H
sames
FEATURES
+ Two current sensor inputs
+ Dual pulse and energy direction outputs
+ No external crystal or resonator required
+ Performs bi-directional power and energy measurement
+ Meets the IEC 521/1036 Specification for Class 1 AC Watt
hour meters
DESCRIPTION
The SAMES SA2007H is a single phase bidirectional dual
element energy metering integrated circuit. It provides a
simple analog interface to a micro-controller and is specifically
designed for meter manufacturers to have full control over the
meter functionality.
The SA2007H has two current sensor inputs. The power
consumption on both inputs are continuously measured. A
typical application would be to monitor Live and Neutral lines
for tamper detection.
+ Protected against ESD
+ Total power consumption rating below 25mW
+ Adaptable to different types of sensors
+ Operates over a wide temperature range
+ Precision voltage reference on-chip
For each current sensor input the SA2007H integrated circuit
has a corresponding pulse output, each generating a pulse
rate with a frequency proportional to the power consumption
measured on the specific channel.
The SA2007H performs active power measurement and takes
the power factor into account. Energy consumption can be
determined by the power measurement being integrated over
time. The energy flow direction information is also available for
each channel.

Description
Analog Ground. The voltage to this pin should be mid-way between VDD and VSS.
Positive supply voltage. The voltage to this pin is typically +2.5V if a shunt resistor is used for
current sensing or in the case of a current transformer a +5V supply can be applied.
Negative supply voltage. The voltage to this pin is typically -2.5V if a shunt resistor is used for
current sensing or in the case of a current transformer a 0V supply can be applied.
Analog Input for Voltage. The current into the A/D converter should be set at 14µARMS at
nominal mains voltage. The voltage sense input saturates at an input current of ±25µA peak.
Inputs for current sensor - Channel 1 and Channel 2. The shunt resistor voltage from each
channel is converted to a current of 16µARMS at rated conditions. The current sense input
saturates at an input current of ±25µA peak.
This pin provides the connection for the reference current setting resistor. A 24kW resistor
connected to VSS sets the optimum operating condition.
This logic input is used to select between latched or unlatched condition for the pulse and
direction outputs.
A logic input is used to reset the latched outputs which is required after an interrupt has
occurred.
The zero crossover of the voltage sense input is signaled on this pin.
Configure / Test inputs. For normal operations these pins must be connected to VSS.
This logic output will indicate a change in status of the pulse or direction outputs.
Pulse outputs. The P1 and P2 outputs give instantaneous pulse outputs of channel 1 and
channel 2 respectively. The pulse is active low with a pulse width of 71.5µs for positive energy
and doubles for reverse energy.
Direction output. These outputs indicate the energy flow direction of each channel.
No Connection.
