FAQs

What is AMC3301DWE?

The AMC3301DWE is a fully-certified, galvanically isolated current sensor developed by Texas Instruments. It is ideal for industrial and automotive applications requiring high-accuracy current sensing, such as motor drives, solar inverters, and power supplies.

How Does AMC3301DWE Work?

The AMC3301DWE works by utilizing a magnetic field generated by the current-carrying conductor to develop a voltage across a Hall-effect sensor. The sensor is galvanically isolated from the current path by a thick oxide layer, providing reliable isolation between the measured current and the sensing circuitry. The voltage generated across the sensor is proportional to the input current, and the output signal is conditioned to provide a linear output proportional to the input current.

How Many Pins does AMC3301DWE have and What are the Functions of the Pinout Configuration?

The AMC3301DWE is housed in a 16-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

VCC1: Positive power supply pin for the primary side.
VCC2: Positive power supply pin for the secondary side.
GND1: Ground pin for the primary side.
GND2: Ground pin for the secondary side.
VOUT: Analog output voltage pin.
NC: Not connected pin.
IN–: Current sense input pin.
IN+: Current sense input pin.
REF–: Reference voltage input pin.
REF+: Reference voltage input pin.
DO: Digital output pin.
CLK: Clock input pin.
CS: Chip select input pin.

What are the Pros and Cons of AMC3301DWE?

Pros:

High Accuracy: Provides high-accuracy current sensing with low drift over temperature.
Galvanic Isolation: Ensures reliable isolation between the measured current and the sensing circuitry.
Wide Input Range: Supports a wide input voltage range and high common-mode rejection ratio (CMRR).
Small Package: The 16-lead SOIC package is space-efficient and suitable for compact designs.
Certified: Fully-certified to industry standards, ensuring safe and reliable operation.

Cons:

Cost: May have a higher cost compared to simpler, non-isolated sensor alternatives.
Complexity: May require careful consideration of noise, grounding, and layout for optimal performance.
External Components: May require additional external components such as filters or amplifiers for specific applications.

Are There Any Equivalents/Alternatives to AMC3301DWE for Recommendation?

The ACS758 from Allegro Microsystems is a similar current sensor with different package options.
Alternatives to the AMC3301DWE include the ICS-314 and ICS-513 from Texas Instruments and the TLI4970 from Infineon Technologies.
