DS1233A-10

Supervisors Overview

The DS1233A-10 is a voltage supervisory circuit from the EconoReset series, designed for precise power monitoring in microprocessor systems. It operates within a supply voltage range of 1.2 V to 5.5 V with a typical quiescent current of 50 uA. The device features a 3.3 V threshold and provides an active low, open drain output. It includes manual reset functionality with a reset delay time of 450 ms. The component supports through-hole installation in a TO-92-3 package and functions reliably across an operating temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Provides precise power monitoring with internal temperature-compensated voltage reference
• Includes manual reset input with internal debouncing circuitry
• Generates power-fail signal to force reset during out-of-tolerance conditions

Supervisors Applications

• Microprocessor system reset control
• Battery-powered equipment power supervision
• Industrial control system voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as variants such as the standard bulk package and tape-and-reel options exist within the DS1233A family. Confirm that the selected part matches the required threshold voltage and packaging format for your design. Note that availability may vary by region and some listings indicate discontinued status for certain configurations. Always cross-reference the manufacturer datasheet for the most current electrical specifications and handling instructions before finalizing procurement.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with manual reset capability is required. The fixed 3.3 V threshold suits applications where the monitored rail aligns with this nominal level. Consider the TO-92-3 package if through-hole mounting is preferred over surface mount alternatives. Ensure the application does not require a watchdog timer or battery backup switch, as these features are absent in this specific model variant.

Supervisors Part Context

This device belongs to the DS1233A EconoReset series, which offers various threshold options for different supply voltages. The series is characterized by its simplicity and low cost, utilizing a TO-92 or SOT-223 package to minimize discrete component requirements. It serves as a fundamental building block for ensuring reliable system startup and recovery in embedded electronics.

Supervisors Replacement Considerations

Other models in the DS1233A series offer different threshold voltages but share similar functional characteristics. Verify pin compatibility and output drive capabilities when substituting with other supervisors from the same manufacturer.
