MAX17525ATP+

Overview

The MAX17525ATP+ is a high-accuracy, adjustable power limiter and current monitor housed in a 20-pin TQFN package. It operates with a supply voltage range of 5.5V to 60V and draws a typical supply current of 1.4mA. The device functions as a step-down converter controller with integrated protection features, including programmable forward current limits and undervoltage lockout. Designed for surface mount installation, it supports an operating temperature range from -40°C to +125°C, ensuring reliability in demanding industrial environments.

Feature Summary

• Provides high-accuracy adjustable power limiting capabilities
• Integrates overvoltage, undervoltage, and overcurrent protection mechanisms
• Features low on-resistance integrated FETs for efficient startup charging

Applications

• Motion system drives
• Human machine interfaces
• Control and automation systems

Procurement Notes

Verify the specific pinout and thermal pad requirements against your PCB layout before finalizing the design. Confirm that the 60V maximum supply voltage aligns with your system's peak input conditions. Ensure the 20-pin TQFN footprint matches your assembly capabilities. Check for any recent lifecycle status updates from Analog Devices regarding this specific part number.

Selection Notes

Select this component when precise power limiting and comprehensive fault protection are required for high-voltage DC-DC applications. It is suitable for designs needing robust undervoltage and overcurrent safeguards within a compact surface-mount form factor. Consider its 60V input capability if interfacing with higher voltage bus systems compared to standard 5V regulators.

Part Context

This device belongs to the Maxim Integrated power management family, specifically designed as a current and power monitor regulator. It serves as a specialized controller for synchronous buck converters, offering advanced protection features not found in basic switching regulators. The integration of power limiting makes it distinct from standard voltage-only controllers.
