Description

The STPM1x family is designed for effective

measurement of active energy in a power line

system using a Rogowski Coil, current

transformer and shunt sensors. This device is

specifically designed to provide all the necessary

features to implement a single phase energy

meter without any other active component. The

STPM1x device family consists, essentially, of two

parts: the analog part and the digital part. The

former, is composed of a preamplifier and first

order

∑ Δ A/D converter blocks, band gap voltage

reference, low drop voltage regulator. The digital

part is composed of a system control, oscillator,

hard wired DSP and interface for calibration and

configuration. The calibration and configuration

are done by OTP cells, that can be programmed

through a serial interface. The configured bits are

used for testing, configuration and calibration

purposes. From two

∑ Δ output signals coming

from the analog section, a DSP unit computes the

amount of consumed active energy. The active

energy is available as a pulse frequency output

and directly driven by a stepper counter. In the

STPM1x an output signal with pulse frequency

proportional to energy is generated. This signal is

used in the calibration phase of the energy meter

application allowing a very easy approach. When

the device is fully configured and calibrated, a

dedicated bit of OTP block can be written

permanently in order to prevent accidental entry

into test mode or changing any configuration bit.
