Overview
The MAX16126TCB/V+ is a supervisory circuit designed for load-dump and reverse-voltage protection. It operates within a supply voltage range of 3V to 30V with a typical quiescent current of 224µA. The device features an adjustable overvoltage threshold starting at 1.2V and provides an open-drain output. It is housed in a 12-TQFN (3x3) package and supports operation from -40°C to +125°C.
Feature Summary
- Provides dedicated protection against automotive load-dump events and reverse voltage connections.
- Features an adjustable overvoltage detection threshold for flexible system configuration.
- Includes power failure detection capability to monitor input supply integrity.
Applications
- Automotive electronic control units requiring robust transient protection
- Industrial systems needing reverse polarity safeguarding
- General-purpose power management circuits with overvoltage monitoring requirements
Procurement Notes
Verify the specific suffix 'V+' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the 12-TQFN package dimensions match your PCB footprint constraints. Check for AEC-Q100 qualification if automotive reliability standards are required for your design implementation.
Selection Notes
Select this component when adjustable overvoltage thresholds are necessary rather than fixed options. Ensure the input voltage range up to 30V aligns with your system's maximum operating conditions. Consider the 224µA quiescent current impact on overall power efficiency during standby modes.
Part Context
This part belongs to the MAX16126 family, which specializes in supervisory functions for harsh environments. It complements other Maxim Integrated PMIC solutions by offering specialized protection rather than general regulation. The TCB variant specifically denotes the 12-TQFN package configuration.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs before considering alternative components from different manufacturers.
