ACS37800KMACTR-030B3-I2C

Overview

The ACS37800KMACTR-030B3-I2C is a Hall-effect current sensor IC designed for DC and AC applications. It features a 30 A current rating, 1.2% accuracy, and a 5 us response time. The device operates on a 2.97 V to 3.63 V supply and provides digital I2C output. It is housed in a 16-WSOIC package with dimensions of 10.21 mm x 7.5 mm x 2.54 mm. Operating temperatures range from -40°C to +125°C, with a frequency range up to 400 kHz.

Feature Summary

• Integrated Hall-effect sensing technology for isolated current monitoring
• Digital I2C interface for direct microcontroller communication
• High accuracy performance suitable for power management systems

Applications

• DC and AC power monitoring circuits
• Industrial motor control systems
• Energy metering equipment

Procurement Notes

Verify the specific suffix '030B3' confirms the 30 A rating and 'I2C' denotes the digital interface. Confirm the 'TR' suffix indicates tape and reel packaging. Ensure the WSOIC-16 package matches your PCB footprint requirements. Check for RoHS compliance status before integration.

Selection Notes

Select this component when precise digital current feedback is required via I2C. The 30 A rating suits moderate power applications. Consider the 1.2% accuracy and 5 us response time for dynamic load conditions. The wide operating temperature range supports industrial environments.
