MCP1501T-18E/CHYVAO

Overview

The MCP1501T-18E/CHYVAO is a buffered voltage reference from the MCP1501 family, manufactured by Microchip Technology. It provides a nominal output voltage of 1.8V with an initial accuracy of 0.1%. The device operates within a supply voltage range of 2.0V to 5.5V and supports an operating temperature range from -40°C to +125°C. It features a maximum temperature coefficient of 50 ppm/°C and can source or sink up to 20 mA of load current. The component is housed in a 6-Lead SOT-23 package and is AEC-Q100 qualified for automotive applications.

Feature Summary

• Utilizes a chopper-based amplifier architecture to minimize drift and offset errors.
• Capable of sourcing and sinking significant load currents for direct drive applications.
• Includes a dedicated shutdown pin for digital control of power consumption.

Applications

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

Procurement Notes

Verify that the ordering suffix CHYVAO corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm that the VAO designation aligns with any specific regional compliance or traceability requirements mandated by your procurement standards before finalizing orders.

Selection Notes

Select this variant when a stable 1.8V reference is needed in space-constrained designs due to its compact SOT-23 form factor. Ensure the input supply voltage remains above the minimum threshold of 2.0V to maintain regulation. Consider the thermal resistance characteristics if the device will operate near the upper limits of the specified temperature range under heavy load conditions.

Part Context

This component belongs to the MCP1501 series of high-precision buffered voltage references. The series offers multiple fixed output voltage options ranging from 1.024V to 5.000V. While other packages like SOIC-8 and WDFN-8 are available, the SOT-23 version is specifically noted for its automotive qualification status.

Replacement Considerations

Direct replacements include other variants within the MCP1501 family such as MCP1501T-25E/CHYVAO or MCP1501T-33E/CHYVAO, provided the output voltage requirement matches. For non-voltage-specific functional swaps, verify compatibility with the MCP1502 series, though pinouts and specifications may differ.
