DS1810-10

Supervisors Overview

The DS1810-10 is a voltage supervisor and reset circuit manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a precision temperature-compensated voltage reference and comparator to monitor the VCC supply status. The device generates an internal power-fail signal when out-of-tolerance conditions are detected, forcing the reset output active. Upon return to tolerance, it maintains the reset state for approximately 150 ms to allow system stabilization. Key electrical parameters include a maximum operating supply voltage of 5.5 V, a minimum operating supply voltage of 1.2 V, and a monitored voltage range between 4.37 V and 4.49 V. It operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Automatically restarts microprocessors following power failure events
• Maintains reset assertion for a fixed duration after power returns to nominal levels
• Integrates precision temperature-compensated voltage reference and sensor
• Features push-pull output driver for low current operation

Supervisors Applications

• Microprocessor system supervision
• Power-fail detection circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm package type and suffix variations match design requirements. Check RoHS compliance status as manufacturing sources may vary. Validate lead times and stock levels directly with suppliers prior to procurement planning.

Supervisors Selection Notes

Select this component for applications requiring precise voltage monitoring with integrated reset timing. Ensure the monitored voltage range aligns with the target system's supply rails. Consider the push-pull output capability for driving loads without external pull-up resistors. Verify thermal performance meets operational environment specifications.

Supervisors Part Context

This part belongs to the EconoReset family of voltage supervisors designed for cost-sensitive and space-constrained applications. It simplifies system design by replacing discrete components typically used for power monitoring and reset generation. The series offers various output configurations and voltage thresholds to suit different processor architectures.

Supervisors Replacement Considerations

Compatible alternatives include DS1811, DS1812, DS1813, and DS1815. Verify output polarity, reset delay characteristics, and monitored voltage thresholds before substitution. Package compatibility must be confirmed for direct replacements.
