MCS1801GS-12-P

Current Sensors Overview

The MCS1801GS-12-P is a board-mount current sensor from Monolithic Power Systems, utilizing Hall-effect technology for linear AC or DC sensing. It features a differential Hall array to cancel stray magnetic fields and provides an analog output. The device operates on a 5V supply with a maximum voltage of 5.5V and minimum of 4.5V. It supports a current rating of ±12.5A with 2.5% accuracy and 200V isolation. Key electrical parameters include a 5us response time, 100kHz frequency range, and operation within -40°C to +125°C. The component is housed in an SOIC-8 package measuring 5mm by 4mm.

Current Sensors Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging configuration, as suffixes may indicate variations in tape-and-reel specifications or handling requirements. Ensure the selected variant matches the required isolation voltage and accuracy class for the target application. Cross-reference the datasheet revision date to confirm compatibility with current manufacturing standards and RoHS compliance status before finalizing procurement orders.

Current Sensors Selection Notes

Select this component when precise linear sensing of AC or DC currents up to 12.5A is required in compact designs. The integrated differential Hall array eliminates the need for external magnetic shielding against stray fields. Choose this part over resistive sensors for applications requiring galvanic isolation and high-frequency response up to 100kHz. Consider the SOIC-8 footprint and 5V supply constraints during PCB layout and power budgeting.

Current Sensors Part Context

This part belongs to the MCS180 series of Hall-effect current sensors from Monolithic Power Systems. The series includes variants with different current ratings and supply voltages, such as the MCS1802 and MCS1803 models. These sensors share common architectural features like differential Hall arrays and analog outputs, designed for robust performance in automotive and industrial environments.

Current Sensors Replacement Considerations

Direct substitutes within the same family include MCS1801GS-12-Z, which shares identical electrical characteristics but differs in packaging format. Other MCS180 series parts offer similar functionality with varying current ratings.
