MAX16126TCD+T

Product Overview

The MAX16126TCD+T from Analog Devices Inc./Maxim Integrated is a surface-mount power management integrated circuit for load-dump and voltage-protection functions in 12-TQFN (3x3) packaging. It is specified for supply voltages from 3V to 30V and an operating temperature range of -40°C to 125°C. The device package is a 12-WFQFN with exposed pad, supporting surface-mount assembly in compact power-protection designs.

Key Features

• Intended for load-dump and voltage-protection applications.
• Supports a supply voltage range of 3V to 30V.
• Supply current is specified at 224µA.
• Rated for operation from -40°C to 125°C.
• Housed in a 12-WFQFN exposed-pad package with a 12-TQFN (3x3) device package.
• The mounting type is surface-mount.

Applications

• Protection of downstream circuitry on supply rails within the 3V to 30V range.
• Transient voltage control in power inputs exposed to load-dump events.
• Voltage protection in compact surface-mount board designs with -40°C to 125°C ambient operation.

Design & Procurement Notes

Designers can use the 3V to 30V supply range and 224µA supply current to evaluate input voltage compatibility and supply-current impact. The -40°C to 125°C operating temperature range should be checked against the final ambient and board thermal conditions. The 12-WFQFN exposed-pad package in a 12-TQFN (3x3) footprint supports surface-mount layout, so pad geometry, solder paste volume, and thermal relief should be reviewed during PCB design. Because the device is specified for load-dump and voltage-protection functions, protection thresholds, transient behavior, and external component requirements should be confirmed from the manufacturer's technical documentation before finalizing the circuit.
