DS1810-5+

Supervisors Overview

The DS1810-5+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed as a 5V EconoReset device with a push-pull output. It utilizes a precision temperature reference and comparator to monitor the VCC power supply status. The component generates an internal power-fail signal when out-of-tolerance conditions are detected, forcing the reset signal active. Upon return to tolerance, it maintains the active reset state for approximately 150 ms to allow system stabilization. It operates within a voltage range of 4.62 V threshold and supports temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Automatically restarts microprocessors following power failure events
• Maintains reset assertion for 150 ms after power supply stabilizes
• Integrates precision temperature-compensated voltage reference and sensor
• Features push-pull output architecture for low current operation

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded systems
• Electronic equipment requiring automatic recovery after power loss

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and electrical characteristics. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary. Ensure the selected variant matches the required operating temperature range and output configuration for the target application design.

Supervisors Selection Notes

Select this component for applications requiring cost-effective power supervision without discrete components. The push-pull output suits low current requirements. Verify that the 5V threshold aligns with the system's VCC levels. Consider the TO-92 or SOT-23 package options based on space constraints and mounting preferences relative to other EconoReset variants.

Supervisors Part Context

The DS1810 belongs to the Maxim Integrated EconoReset family, which provides simple, low-cost supervisory solutions. This series includes variants with different thresholds and outputs, such as open-drain or active-high configurations. The DS1810 specifically targets 5V systems with its push-pull output, distinguishing it from other family members like the DS1811 or DS1815.

Supervisors Replacement Considerations

Compatible substitutes include DS1810R-5+T&R-W (SOT-23 package) and DS1810-5/T&R. Verify pinout compatibility and output drive strength before substitution.
