DS1233-10

Supervisors Overview

The DS1233-10 is a voltage supervisory circuit from the EconoReset series, designed for monitoring power supply integrity in microprocessor systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 3.3 V. The device provides an active low, open-drain reset output with a typical reset delay time of 450 ms. It supports manual reset functionality via an internal pushbutton interface and includes power-fail detection capabilities. The component is available in TO-92-3 through-hole packages and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated manual reset capability with internal debouncing for external switch inputs
• Precise power-fail signal generation to detect out-of-tolerance voltage conditions
• Low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor system power supervision
• Embedded controller reset management
• Portable electronic device power monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability variations. Confirm package type and suffix designations match specific hardware requirements. Check RoHS compliance status as indicated by official documentation. Ensure storage and handling procedures adhere to moisture sensitivity levels specified in the datasheet to maintain device reliability during assembly processes.

Supervisors Selection Notes

Select this component when a dedicated supervisor for 3.3 V rails is required with manual reset support. Compare against other EconoReset variants based on specific threshold accuracy and package constraints. Consider thermal performance and operating temperature limits relative to the target application environment. Evaluate pin compatibility if replacing existing designs using similar supervisory architectures.
