MCP1502T-10E/CHYVAO

Overview

The MCP1502T-10E/CHYVAO is a buffered voltage reference with an output of 1.024V and initial accuracy of 0.1%. It operates from 1.65V to 5.5V, consuming 140µA typical current. The device features a maximum temperature coefficient of 7 ppm/°C across -40°C to +125°C. It provides ±20mA drive capability and includes a shutdown pin.

Feature Summary

• Chopper-based amplifier architecture reduces drift to zero for high precision
• Capable of sourcing and sinking up to 20mA load current
• Includes active-low digital shutdown control for power management

Applications

• Precision data acquisition systems
• Electric vehicle battery management systems
• High-resolution data converters
• Medical equipment applications

Procurement Notes

Verify the specific suffix CHYVAO against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the operating environment remains within the specified -40°C to +125°C range to maintain the guaranteed 7 ppm/°C temperature coefficient and 0.1% initial accuracy parameters.

Selection Notes

Select this component when a stable 1.024V reference is required with low noise and high drive capability. The chopper-stabilized design minimizes long-term drift compared to standard bandgap references. Consider the 6-lead SOT-23 package constraints for thermal management if operating near maximum load currents.

Part Context

This part belongs to the MCP1502 family of high-precision buffered voltage references. It shares architectural similarities with the MCP1501 but offers higher output current capabilities. The device utilizes curvature-compensated bandgap technology combined with digital calibration to achieve automotive-grade reliability under AEC-Q100 standards.

Replacement Considerations

The MCP1501 serves as a related alternative in the same product family. Verify that the lower drive current of the MCP1501 meets the application requirements before substitution.
