Allegro MicroSystems ACS37800KMACTR-030B3-SPI

Overview

ACS37800KMACTR-030B3-SPI from Allegro MicroSystems is a integrated power-monitoring IC for current, voltage, and power measurement in embedded systems. Combining current sensing, voltage measurement, and digital telemetry in a 16-pin SOIC package, it gives the host controller direct visibility into rail behavior without building a separate sensing and reporting chain from discrete parts.

For engineers reviewing the ACS37800KMACTR-030B3-SPI datasheet, ACS37800KMACTR-030B3-SPI pinout, ACS37800KMACTR-030B3-SPI application, or ACS37800KMACTR-030B3-SPI equivalent, this device is widely used in power telemetry nodes, smart power rails, industrial energy monitoring, and embedded systems that need integrated current sensing with digital reporting.

Technical Context

In embedded power-monitoring sections, ACS37800KMACTR-030B3-SPI tracks current, voltage, and calculated power so the system controller can supervise rail loading, subsystem consumption, and fault conditions through a digital interface such as I2C or SPI, depending on the option code. This makes ACS37800KMACTR-030B3-SPI a good fit for smart power rails, industrial energy-monitoring sections, and telemetry-heavy embedded platforms where integrated measurement and reporting are more valuable than a discrete shunt-plus-ADC implementation.

Key Specifications

Pinout & Package

The ACS37800KMACTR-030B3-SPI pinout is implemented in the 16-pin SOIC package and combines the monitored-rail pins, control pins, and reset, watchdog, sequencing, or fault outputs required by the device function.

For PCB design, the main consideration is routing the monitored rails, control pins, and fault or sequencing outputs according to the actual device role.

Key Features

• Integrated telemetry simplifies board-level power measurement.
• Digital output eases host-system monitoring.
• Useful in smart rails and industrial monitoring nodes.
• Reduces discrete sense and interface circuitry.

Applications

Equivalent & Alternatives

Compared with ACS37800KMACTR-030B3-I2C, ACS37800KMACTR-030B3-SPI selection depends on the required current range and whether the system uses SPI or I2C telemetry. Compared with ACS37800KMACTR-090B3-I2C, ACS37800KMACTR-030B3-SPI fits best when the design keeps the same integrated power-monitoring approach but needs a different sensing range or interface.

Quality

ACS37800KMACTR-030B3-SPI should be sourced through traceable channels with attention to package identity, orderable suffix, and whether the replacement still matches the intended device role.

Production validation should include startup behavior, threshold accuracy, fault response, and the sequencing or monitoring performance that matters for the real end application.

Availability

ACS37800KMACTR-030B3-SPI is available at Aetrix Electronics and is suitable for maintenance, new design qualification, and repeatable production support in systems that depend on this exact device role.

Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.

For production builds, confirming lifecycle position, package option, operating range, and sourcing continuity helps reduce replacement risk.

Manufacturer

Allegro MicroSystems is a semiconductor manufacturer whose portfolio includes sensor, driver, interface, and power-management devices used across automotive, industrial, and embedded electronics.

The ACS37800 line is used in embedded power-monitoring applications where current, voltage, and power telemetry must be reported digitally in one integrated sensing path.
