ACS37800中文资料Highly Isolated, Programmable AC and DC Power Monitoring IC数据手册Allegro规格书

描述 Description

When you need to add AC power monitoring or DC power monitoring to your device, our ACS37800 power monitoring IC simplifies your task tremendously. Our integrated current sensor technology at the core of this device leverages the Hall effect and galvanic isolation to deliver reinforced isolation without extra board space. When powered from the same supply as the microcontroller unit, multiple power supplies and digital isolation ICs are not needed, which reduces the size of your printed circuit board (PCB).

The sensing scheme—isolated current is measured by two Hall plates that deferentially sense the magnetic field of the integrated conductor—eliminates the need for external sense resistors, current transformers, and Rogowski coils. This sensing scheme further reduces the size of your PCB and delivers a highly integrated power monitoring IC that eliminates errors caused by stray magnetic fields.

Multiple parameters are user programmable—including averaging and zero-crossing time or channel, and fault level—and all sensor features and key power measurements can be read out through an inter-integrated circuit (I2C) interface or a serial port interface (SPI). Two dedicated pins for voltage or current zero crossing (suitable for light-dimming applications) and fast overcurrent fault (for short-circuit detection) can also be configured to flag a Vrms under/overvoltage event. The graphical user interface (available for download in our Software Portal) facilitates device configuration.

The ACS37800 is provided in a small, low-profile, surface-mount SOIC16 wide-body, lead-free (pb-free) package. The ACS37800 is fully calibrated prior to shipment from the factory. Further calibration in application can improve accuracy.
