MAX6375UR23

Supervisors Overview

The MAX6375UR23+T is a single-channel ultra-low-power voltage detector manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a typical threshold voltage of 2.3 V, with specific under-voltage and over-voltage thresholds documented at 2.254 V and 2.346 V respectively. The device offers 2.5% accuracy and consumes only 1 µA of quiescent current. It utilizes an active low, open-drain output configuration without manual reset or watchdog timer capabilities. The component is housed in a compact SOT-23-3 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-low power consumption of 1 µA for extended battery life
• Precision voltage monitoring with 2.5% threshold accuracy
• Compact SOT-23-3 surface-mount packaging
• Active low open-drain output for direct logic interfacing

Supervisors Applications

• Battery-powered portable electronics
• Microprocessor system supervision
• Low-voltage power management circuits
• Consumer devices requiring minimal standby current

Supervisors Procurement Notes

Verify the exact suffix (+T) for reel packaging requirements. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices as Maxim Integrated products may undergo lifecycle changes. Ensure the specific threshold voltage variant matches the design requirement, as the MAX6375 family offers multiple fixed options.

Supervisors Selection Notes

Select this component when a fixed 2.3 V threshold is required for systems operating between 1.2 V and 5.5 V. Consider the open-drain output if external pull-up resistors are acceptable. Evaluate the 1 µA current draw against total system budget. Verify that the SOT-23-3 footprint fits the PCB layout constraints compared to SC-70 alternatives.

Supervisors Part Context

The MAX6375 series belongs to Maxim's ultra-low-power voltage supervisor family. It provides reliable reset signals for microprocessors and memory devices. The UR23 designation specifically indicates the SOT-23-3 package and the 2.3 V threshold setting within the broader MAX6375 product line.

Supervisors Replacement Considerations

Check for MAX6375UR23+ (non-tape version) if reel packaging is not required. Other MAX6375 variants with different thresholds may serve as functional substitutes if voltage levels differ.
