MAX6793TPSD1+

Supervisors Overview

The MAX6793TPSD1+ is a dual-output linear regulator with integrated supervisory functions, designed for automotive applications. It features an input voltage range of 5V to 72V and consumes only 68µA quiescent current. Each output provides up to 150mA load current. Standard fixed output voltages include 5V, 3.3V, 2.5V, and 1.8V, while adjustable versions support 1.8V to 11V. The device operates from -40°C to +125°C in a 20-pin TQFN package.

Supervisors Feature Summary

• Ultra-low quiescent current consumption of 68µA enables extended battery life in power-sensitive environments.
• Wide 5V to 72V operating input range withstands automotive load-dump conditions without damage.
• Dual outputs deliver up to 150mA each, supporting simultaneous supply requirements for multiple subsystems.
• Integrated supervisory circuitry includes programmable watchdog timers and reset monitoring for system reliability.

Supervisors Applications

• Automotive electronic control units (ECUs) requiring high-voltage tolerance
• Infotainment systems needing stable dual-rail power supplies
• Body control modules with strict low-power standby requirements
• Sensor interfaces demanding precise voltage regulation under varying loads

Supervisors Procurement Notes

Verify the exact suffix 'TPSD1+' against the manufacturer's official datasheet to confirm pinout, output voltage configuration, and package type. Confirm RoHS compliance status and lead-free certification through authorized distributors. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual isolated rails are needed alongside system supervision in harsh electrical environments. Ensure the required output voltage matches available fixed options or verify external resistor network compatibility for adjustable variants. Validate thermal performance within the specified -40°C to +125°C range for your enclosure design.

Supervisors Part Context

Part of the MAX6791–MAX6796 family of high-voltage micropower regulators. Shares core architecture with single-output counterparts like MAX6795 but offers dual-channel capability. Designed specifically for automotive grade reliability standards including AEC-Q100 qualification where applicable.

Supervisors Replacement Considerations

Direct substitutes include other MAX679x series parts with matching pinouts and electrical characteristics. Verify equivalent quiescent current, load current capacity, and supervisory function compatibility before substitution.

Supervisors FAQ
