MAX4718EBC

Overview

The MAX4718EBC is a bidirectional, high-side current-sense amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a precision internal sense resistor and operates with a supply voltage range of 3V to 36V. The device provides accurate monitoring for both charge and discharge currents in portable systems. It includes a shutdown mode with maximum supply current of 100µA during operation and 18µA in shutdown. The component is housed in an 8-pin DIP or SOIC package.

Feature Summary

• Complete high-side current sensing capability
• Precision internal sense resistor for accuracy
• Bidirectional monitoring for charge and discharge cycles
• Low power consumption with dedicated shutdown mode

Applications

• Portable PCs including notebooks and subnotebooks
• Smart battery packs

Procurement Notes

Verify the specific suffix EBC against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status as older Maxim parts may vary. Check for obsolescence notices from Analog Devices. Ensure pinout compatibility with existing PCB layouts before procurement.

Selection Notes

Select this component when high-side monitoring is required without interfering with ground paths. The internal resistor simplifies design compared to external shunt solutions. Verify that the 3A sense capability meets system requirements. Consider the 2% accuracy over temperature for precision applications.

Part Context

The MAX4718EBC belongs to the MAX471/MAX472 family of current-sense amplifiers. This series is designed for critical battery and DC power-line monitoring in portable electronics. The EBC suffix typically denotes a specific package variant within the broader MAX471 product line.

Replacement Considerations

MAX471ESA is a confirmed substitute part number listed in public documentation.
