Manchester, NH, Jan. 06, 2021 (GLOBE NEWSWIRE) — Allegro MicroSystems, a global leader in power and sensing for motion control and energy-efficient systems, announced the launch of the ACS37800<\/a>, a Hall-effect power monitoring IC for single-phase AC and DC solutions in a small PCB footprint. Another industry-first innovation, Allegro\u2019s ACS37800 is an integrated power monitoring chip that allows simultaneous measurement of power, voltage, and current for AC and DC signals with an isolation rating of up to 1480 Vpk in a small SOIC16W package, reducing the solution BOM size, cost, and complexity.<\/p>\n

“Our newest power monitoring chip is a gamechanger for IoT devices, smart lighting, data centers, and telecom applications, in particular,” says Shaun Milano, Business Unit Director for Current Sensors at Allegro. “We\u2019ve improved on our first-generation integrated solution by adding the ability to measure voltage, current and power in AC as well as DC at the same time \u2013 and with reinforced isolation, our customers can eliminate many expensive components on their PCBs. The ACS37800 dramatically simplifies measuring power in a unique single-chip solution.”<\/p>\n

The new ACS37800<\/a> allows devices to easily track power consumption and to optimize energy use by detecting reduced power efficiency for predictive maintenance. This makes the ACS37800 ideal for motor control, building automation, and a variety of green industrial applications.<\/p>\n

\n Extensive integration and power triangle calculations simplify BOM and shrink time to market<\/strong>\n <\/p>\n

Offered in an efficient SOIC16 footprint, the ACS37800 further reduces PCB size and significantly reduces bill of materials (BOM) cost and complexity by eliminating the need for many components that competitive solutions require in similar conditions. For example, the integrated 517\u00a0Vrms reinforced isolation enables current sensing without expensive opto-isolators, Rogowski coils, oversized current transformers, isolated operational amplifiers, or shunt resistors.<\/p>\n

Thanks to its onboard regulator, the ACS37800 can be powered from the same voltage supply as the system microprocessor (5\u00a0V or 3.3\u00a0V).<\/p>\n

The ACS37800 simplifies common power triangle measurements by calculating parameters such as the active, reactive, and apparent power as well as instantaneous and RMS values of the current, voltage, or power. Furthermore, the ACS37800 is able to average these parameters with many instantaneous measurements over a one minute period, avoiding inaccuracies when waveforms are asymmetric. These features reduce the reliance on microcontroller unit (MCU) resources for critical calculations.<\/p>\n

\n The right balance of programmability for a broad range of applications<\/strong>\n <\/p>\n

Thanks to impressive levels of flexibility and configurability, users can program the ACS37800<\/a> to fit a variety of unique application needs. The device allows designers to choose from a factory-programmed I2C or SPI interface, depending on whether the user prefers low noise or multiple addressing\u2014and in I2C mode, it provides zero-crossing detection pinout, making LED dimming control easy. Users can also program thresholds for under\/overvoltage, current\/voltage gain and offset, and overcurrent trip point via EEPROM, allowing them to optimize their system from \u00b130\u00a0A to \u00b1180\u00a0A and from \u201340\u00b0C to 125\u00b0C.<\/p>\n

Combining Allegro’s factory programming of sensitivity and offset with vast user programmability allows designers to balance between time-to-market and customization in the increasingly competitive energy-efficient applications, such as:<\/p>\n
