FAQs

What is MAX4376TAUK-T?

The MAX4376TAUK-T is a precision, low-drift, high-side current-sense amplifier designed by Maxim Integrated. It is ideal for applications requiring accurate monitoring of current levels, such as power management, motor control, and battery charging systems.

How Does MAX4376TAUK-T Work?

The MAX4376TAUK-T works by amplifying small differential voltages across a shunt resistor in the high-side current path. It provides a high-accuracy output voltage proportional to the measured current, enabling precise current monitoring and control. The amplifier features low input offset voltage and temperature drift, ensuring stable and accurate current measurements over a wide temperature range.

How Many Pins does MAX4376TAUK-T have and What are the Functions of the Pinout Configuration?

The MAX4376TAUK-T is housed in a 5mm x 5mm, 8-pin μMAX package. The pinout configuration includes:

  • IN+: Non-inverting input pin for the current-sense signal.
  • IN-: Inverting input pin for the current-sense signal.
  • VCC+: Positive power supply pin.
  • VCC-: Negative power supply pin (ground).
  • VOUT: Amplified output voltage proportional to the current sense input.

What are the Pros and Cons of MAX4376TAUK-T?

Pros:

  • Precision: Provides accurate current measurements with low offset voltage and drift.
  • High-Side Sensing: Allows monitoring of current levels in the high-side of the circuit, without the need for additional isolation components.
  • Wide Temperature Range: Maintains stable performance over a wide temperature range, suitable for harsh environments.
  • Small Package: The compact μMAX package saves board space and enables high-density designs.

Cons:

  • External Components: May require additional external components such as a shunt resistor for specific current-sensing applications.
  • High-Side Sensing Behavior: Proper design considerations are required to ensure accurate high-side current measurements.

Are There Any Equivalents/Alternatives to MAX4376TAUK-T for Recommendation?

  • The INA138 from Texas Instruments is a similar high-side current-sense amplifier offering precision performance.
  • Alternatives to the MAX4376TAUK-T include the LTC6101 from Analog Devices and the TSC2010 from STMicroelectronics.
