• Bandwidth: 200kHz (typical)
• Quiescent Current: 85µA (typical)
• Operating Temperature Range: -40°C to +85°C
• Package: 6-Pin SOT23-6

Descriptions:

• The MAX4173TEUT+T is a precision, high-side current-sense amplifier designed for monitoring current in power management, battery charging, and motor control applications.
• It operates with a wide input common-mode voltage range, making it suitable for high-voltage systems.
• The device provides a ground-referenced output proportional to the current flowing through an external sense resistor.

Features:

• High-Side Current Sensing: Eliminates the need for a low-side shunt resistor.
• Wide Input Voltage Range: Supports applications up to +76V.
• Low Offset Voltage: ±500µV (max) for accurate current measurement.
• Low Power Consumption: Ideal for battery-powered systems.
• Fixed Gain Options: Simplifies design with no external components required for gain setting.
• Small Form Factor: 6-Pin SOT23-6 package for space-constrained applications.
