MAX16126TCD/V+

Overview

The MAX16126TCD/V+ is a supervisory circuit designed for load-dump and reverse-voltage protection, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 30 V and features an adjustable overvoltage threshold of 1.2 V. The device utilizes a 12-TQFN (3x3) surface-mount package and supports SMD/SMT installation. It functions reliably across a temperature range of -40°C to +125°C, with a typical operating supply current of 224 uA. The component includes power-fail detection capabilities and holds AEC-Q100 qualification for automotive applications.

Feature Summary

• Provides integrated protection against load-dump events and reverse-voltage conditions in power systems.
• Features an adjustable overvoltage threshold to accommodate specific system requirements.
• Includes power-fail detection functionality for monitoring input voltage integrity.

Applications

• Automotive electronic systems requiring robust voltage supervision
• Load-dump protection circuits in vehicle power distribution
• Reverse-voltage protection for sensitive electronic components

Procurement Notes

Verify the specific suffix 'V+' indicates the required environmental or packaging specifications for your application. Confirm that the 12-TQFN package dimensions align with your PCB layout constraints. Ensure the adjustable threshold settings meet the precise voltage protection levels required by the target circuit design before finalizing procurement.

Selection Notes

Select this component when dedicated load-dump and reverse-voltage protection is required alongside voltage supervision. The adjustable threshold allows flexibility for various input voltage standards. Consider the 12-TQFN package size and the wide operating temperature range suitable for harsh environments. Verify compatibility with existing control logic due to the open-drain output type.

Part Context

The MAX16126 series belongs to Analog Devices' portfolio of supervisory circuits focused on power management and protection. This specific part integrates protection functions typically handled by discrete components, simplifying the bill of materials. It is designed for high-reliability applications where voltage anomalies can cause system failure, particularly in automotive and industrial sectors.

Replacement Considerations

Direct substitutes include other variants within the MAX16126 family such as MAX16126TCA+T, MAX16126TCC+T, and MAX16126TCB+T, which share similar protection functionalities but may differ in specific pin configurations or threshold adjustments. Always verify datasheet compatibility regarding package and electrical characteristics.
