system control, oscillator, hard wired DSP and
SPI interface.
There is also an OTP block, which is controlled
through the SPI by means of a dedicated
command set. The configured bits are used for
testing, configuration and calibration purpose.
From a pair of
鈭?/div>
鈭?/div>
output signals coming from
analog section, a DSP unit computes the amount
of consummated active, reactive and apparent
energy, RMS and instantaneous values of voltage
and current. The results of computation are
available as pulse frequency and states on the
digital outputs of the device or as data bits in a
data stream, which can be read from the device
by means of SPI interface. This system bus
interface is used also during production testing of
the device and/or for temporary or permanent
programming of bits of internal OTP. In the
STPM01 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
entering into some test mode or changing any
configuration bit.
TSSOP20
Description
The STPM01 is designed for effective
measurement of active, reactive and apparent
energy in a power line system using Rogowski
Coil, Current Transformer and Shunt sensors.
This device can be implemented as a single chip
1-phase energy meter or as a peripheral
measurement in a microcontroller based 1-phase
or 3-phase energy meter. The STPM01 consists,
essentially, of two parts: the analog part and the
digital part. The former, is composed by
preamplifier and 1st order
