MAX31963AUM+T

Serializers, Deserializers Overview

The MAX31963AUM+T is a high-side current sensor manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 2.7 V to 5.5 V and features a supply current of 400 µA. The device provides a bidirectional output voltage proportional to the sensed current, with a typical sensitivity of 10 mV/A. It supports shunt resistances up to 100 mΩ and includes an internal reference voltage of 2.5 V. The component functions reliably across a temperature range of -40°C to +85°C.

Serializers, Deserializers Feature Summary

• Bidirectional current sensing capability for both sourcing and sinking applications
• Integrated precision amplifier with fixed gain for direct microprocessor interface
• Low quiescent current consumption suitable for battery-powered systems

Serializers, Deserializers Applications

• Battery management systems in portable electronics
• Current monitoring in USB-powered devices
• Power distribution units requiring precise load measurement

Serializers, Deserializers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the SOT-23-6 package. Confirm RoHS compliance status through manufacturer documentation prior to integration into final assemblies.

Serializers, Deserializers Selection Notes

Select this component when bidirectional sensing is required within a low-voltage environment. Evaluate the maximum expected current against the shunt resistor value to ensure the output does not exceed the supply rail. Consider the 400 µA supply current impact on overall system power budget during active operation phases.

Serializers, Deserializers Part Context

This part belongs to the MAX31963 family of current sensors designed for low-voltage applications. It integrates signal conditioning circuitry to simplify system design by eliminating external amplifiers. The device is optimized for cost-sensitive consumer electronics where space and power efficiency are critical constraints.

Serializers, Deserializers Replacement Considerations

Check for pin-compatible alternatives such as the MAX31962 if unidirectional sensing suffices. Verify that substitute parts maintain the same 10 mV/A sensitivity and 2.7 V minimum operating voltage to ensure circuit functionality without modification.
