STPM13ATR Descripción general
An energy metering IC is a specialized measurement and control component that converts current and voltage information into accumulated or instantaneous energy-related data. STPM13ATR belongs to the broader hierarchy of energy-metering ICs, measurement semiconductors, analog and mixed-signal integrated circuits, and power-management monitoring devices. Its pulsed output provides a convenient interface for an external counter or system controller, while digital calibration supports configuration and measurement adjustment during manufacturing or system setup.
The STPM13 family is described as supporting single-phase energy measurement with sensor inputs suitable for common current-sensing arrangements. The verified listing specifically names shunt, current-transformer, and Rogowski-coil sensors, as well as live and neutral monitoring for STPM13/14 variants. These features allow the device to be evaluated for different meter architectures, but the exact electrical limits, calibration procedure, register map, and timing values must be taken from the manufacturer datasheet.
STPM13ATR is packaged in a 20-TSSOP surface-mount package. The package provides a compact form factor for meter electronics, and the available DigiKey result lists the part as a 20-TSSOP single-phase meter IC. Because the supplied data does not include the full electrical tables or a verified pin diagram, individual pin assignments and absolute minimum or maximum ratings are not reproduced here. The manufacturer datasheet should be consulted before PCB routing or production qualification.
Typical applications include single-phase residential electricity meters, industrial energy-monitoring equipment, smart-meter power calculations, load-monitoring modules, and embedded systems that consume pulse information. The pulsed output can be connected to a counter, capture input, or energy-management controller. The choice of current sensor and the calibration strategy remain important design decisions because they influence signal conditioning, measurement accuracy, and metrology validation.
For a new design, verify the exact STPM13ATR variant, supply requirements, sensor-input configuration, pulse-output behavior, and package pinout against the official STMicroelectronics datasheet. This page combines the verified distributor classification, package information, and family-level feature description with practical sourcing and design guidance.

Aplicaciones típicas
STPM13ATR es adecuado para 6 aplicacións: Single-Phase Residential Smart Meter, Industrial Energy Monitoring, Smart-Meter Load Control, Energy-Management Gateway, Embedded Metering Controller, Load-Monitoring Instrument.
Single-Phase Residential Smart Meter
STPM13ATR fits a single-phase smart-meter signal chain when the design needs energy accumulation information in a compact 20-TSSOP device. Its verified pulsed output can feed a counter or system controller, while digital calibration can support production adjustment of the measurement path. The same feature set is useful for residential energy displays, load-control gateways, and utility-side monitoring modules. Exact sensor ranges, accuracy limits, calibration registers, and metrology certification are not included in the supplied data, so those requirements must be verified against the official datasheet before product qualification.
Recomendado
Industrial Energy Monitoring
For industrial equipment and facility monitoring, STPM13ATR can provide a digital pulse output derived from single-phase energy measurement. The pulse signal can be counted by a data-acquisition system, programmable controller, or communications gateway without relying on an analog display path. The verified feature description also identifies shunt, current-transformer, and Rogowski-coil sensor arrangements, giving designers several sensing architectures to evaluate. Actual accuracy, bandwidth, isolation, and operating-range requirements are not provided in the supplied data and should be established from the manufacturer documentation.
Recomendado
Smart-Meter Load Control
STPM13ATR can act as the measurement element in a load-control or demand-management subsystem because its pulsed output provides an event stream proportional to measured energy. A controller can count pulses, calculate consumption over time, and trigger alarms, display updates, or load-shedding commands. The 20-TSSOP surface-mount package helps preserve board area in compact meter electronics. Before implementation, confirm pulse polarity, maximum pulse frequency, input filtering, supply decoupling, and calibration behavior from the STMicroelectronics datasheet because these values are not included in the verified search excerpts.
Recomendado
Energy-Management Gateway
STPM13ATR is suitable as a front-end measurement device for an energy-management gateway that must aggregate consumption from a single-phase branch circuit. Its digital calibration feature can support board-level adjustment, while the pulsed output provides a simple interface to a counter or communications processor. The device can be evaluated with different sensor types, including shunt and current-transformer arrangements described in the available family information. Designers must confirm electrical limits, sensor conditioning, isolation strategy, and environmental requirements before using the IC in a deployed gateway.
Recomendado
Embedded Metering Controller
An embedded controller can use STPM13ATR when it needs a dedicated single-phase energy-measurement block with a pulse interface rather than a general-purpose analog front end. The compact 20-TSSOP package and digital calibration capability make the device suitable for evaluation in custom meter electronics, utility monitoring boards, and embedded energy products. Because the supplied data does not include the complete pinout, register definitions, or timing diagrams, the controller firmware and PCB interface should be based only on the official manufacturer documentation.
Recomendado
Load-Monitoring Instrument
STPM13ATR can be evaluated in load-monitoring instruments that convert single-phase energy consumption into countable pulses. This approach is useful for laboratory equipment, appliance controllers, and compact power-monitoring modules where a digital output is easier to process than a high-resolution analog waveform. The verified data confirms pulsed output and digital calibration but does not specify pulse-width limits, accuracy grade, or maximum input current. Those missing details must be validated from the STMicroelectronics datasheet and the selected current-sensor implementation.

Notas de diseño
Before routing the board, obtain the current STPM13ATR pinout and 20-TSSOP land pattern from the manufacturer documentation. The supplied data confirms the package family but does not identify individual pins, so do not infer sensor, supply, calibration, or pulse connections from the package name. Check connector polarity, exposed pad requirements, and assembly clearance against the official package drawing.
Choose the current-sensing architecture as part of the PCB design rather than treating it as a later analog add-on. The available description names shunt, current-transformer, and Rogowski-coil sensors, but it does not provide input ranges or bandwidth. Keep sensor traces short, preserve the intended grounding and isolation arrangement, and verify filtering and surge requirements against the complete datasheet and system metrology requirements.
Do not use the listed 5 V nominal supply value as a complete electrical specification or infer pulse timing from the pulsed-output description. Confirm input-voltage limits, supply current, startup behavior, pulse width, pulse polarity, calibration method, and operating-temperature limits in the manufacturer datasheet. Production firmware should also be validated against the actual sensor and counter interface.
Información de cumplimiento
The supplied verified data does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. Compliance must be confirmed from the current manufacturer documentation or distributor records.
