Overview
The MAX6328XR26+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.63 V with an accuracy of 1.5%. The device provides an active low, open-drain reset output with a typical reset delay time of 185 ms. It consumes a maximum operating supply current of 500 nA and supports power dissipation up to 174 mW. The component functions in temperatures from -40°C to +85°C and is housed in a 3-pin SC-70 package.
Feature Summary
- Ultra-low-power consumption suitable for battery-operated systems
- Fixed threshold voltage monitoring for single-input supervision
- Active low open-drain reset signal generation
Applications
- Portable electronic devices requiring power management
- Battery-powered instrumentation systems
- Microprocessor reset circuits in embedded applications
Procurement Notes
Verify the specific suffix 'XR26' to confirm the 2.63 V threshold and SC-70 package configuration. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status through official manufacturer documentation before integration into production designs.
Selection Notes
Select this component when a fixed 2.63 V supervision level is required for low-power applications. The SC-70 package offers space efficiency for compact designs. Consider the 185 ms reset delay and 500 nA quiescent current against system timing and power budget constraints during the design phase.
Part Context
This part belongs to the MAX6328X series of ultra-low-power reset circuits. The series includes variants with different threshold voltages and packages. The MAX6328XR26+T specifically denotes the 2.63 V threshold version in the SC-70-3 package, designed for simple voltage supervision without manual reset or watchdog functionality.
Replacement Considerations
Cross-reference tools may suggest parts like NCP803SN263T1G for similar threshold voltages, but verify package differences (SOT-23 vs SC-70) and electrical characteristics carefully.
