MAX17613BATP+T

Overview

The MAX17613BATP+T is a current limiter and system protection device from the Olympus series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 60V and features an integrated FET with a typical on-resistance (RON) of 130mΩ. The device provides programmable current limiting up to 3A with ±3.5% accuracy across the operating temperature range. It supports overvoltage and undervoltage protection with externally adjustable thresholds via resistors. Unlike variants A and C, the B version allows bidirectional current flow. It includes thermal shutdown protection and is housed in a compact 20-pin TQFN-EP package.

Feature Summary

• Integrated system protection with adjustable overvoltage and undervoltage lockout thresholds
• Programmable current limiting behavior including auto-retry, constant limit, and latch modes
• Bidirectional current conduction capability allowing reverse flow from output to input
• Internal sense voltage proportional to instantaneous current for ADC monitoring

Applications

• Industrial PLCs and control network modules
• Battery-powered modules and sensor systems
• Process instrumentation and weighing/metering systems
• Hot-swap applications requiring surge current control

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'B' variant designation ensures bidirectional current flow compatibility with your circuit design. Ensure the 20-TQFN exposed pad footprint matches your PCB layout requirements. Validate that the 4.5V to 60V input range aligns with your system's power specifications.

Selection Notes

Select this component for applications requiring robust system protection against voltage faults and inrush currents. Choose the MAX17613B variant specifically if reverse current flow is necessary, as opposed to the blocking A or C versions. Consider the integrated FET and low RON for space-constrained designs aiming to reduce external bill of materials. Evaluate the programmable fault response modes to match system recovery requirements.
