MAX16127TC+

Overview

The MAX16127TC+ is a supervisory circuit designed for load-dump and reverse-voltage protection. It monitors input voltages ranging from -36V to 90V with a supply voltage of 3V to 30V. The device features an adjustable reset threshold between 1.2V and 1.25V, an active low open-drain output, and operates within a temperature range of -40°C to +125°C. Packaged in a 12-pin TQFN (3.1 x 3.1 x 0.75mm) surface-mount format, it provides high-accuracy monitoring without manual reset or watchdog timer functions.

Feature Summary

• Provides robust power-system supervision for safety-critical automotive applications
• Monitors voltages from 1.1V to 5V using a factory-set reset threshold
• Delivers load-dump and reverse-voltage protection capabilities

Applications

• Automotive electronics requiring reverse-voltage protection
• Industrial control systems needing robust power management
• Safety-critical automotive applications demanding power-system supervision

Procurement Notes

Verify current availability status as the component may be subject to limited supply or factory special orders. Confirm that the specific package variant matches the 12-TQFN requirement. Ensure the operating temperature range meets the application's environmental specifications. Validate that the input voltage monitoring range aligns with system requirements before procurement.

Selection Notes

Select this component when high-accuracy voltage monitoring is required alongside reverse-voltage protection. The adjustable reset threshold allows customization for specific voltage levels. Consider the 12-pin TQFN package for space-constrained designs. Verify compatibility with the required supply voltage range and operating temperature extremes for the target environment.
