STPM11/12/13/14

Single phase energy metering IC with pulsed output

and digital calibration

Feature summary

■ Ripple free active energy pulsed output

■ Direct stepper counter drivers

■ Shunt, current transformer, Rogowsky coil

sensors

■ Live and neutral monitoring (STPM13/14)

TSSOP20

■ Easy and fast digital calibration at only one

load point

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.

■ No-load, negative power and tamper indicators

■ Integrated linear VREGS

■ RC (STPM11/13) or crystal oscillator

(STPM12/14)

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 ∑∆ 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.

■ Support 50÷60 HZ - IEC62052-11, IEC62053-

2X specification

■ Less than 0.1% error

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 ∑∆ A/D converter blocks, band gap
