DS1233A-10+

Supervisors Overview

The DS1233A-10+ is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc. (Maxim Integrated). It features a single monitored input with an active low, open-drain output and manual reset capability. The device operates within a supply voltage range of 1.2 V to 5.5 V and has a typical operating current of 50 uA. Key electrical parameters include a threshold voltage of 3.3 V, a reset delay time of 450 ms, and a power-fail detection function. It is housed in a TO-92-3 package for through-hole mounting and supports an extended industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides manual reset functionality alongside automatic power-on reset capabilities.
• Includes integrated power-fail detection to monitor supply voltage integrity.
• Features an open-drain output structure suitable for interfacing with various logic families.

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Portable instrumentation power management

Supervisors Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance details as sources vary. Ensure the specific suffix matches the required package and pinout configuration. Cross-reference datasheet revisions to validate electrical characteristics against design requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with manual reset is required. The TO-92-3 package suits through-hole designs. Verify that the 3.3 V threshold aligns with the target system voltage. Consider the 450 ms reset delay duration relative to processor startup times. Evaluate the open-drain output compatibility with downstream logic levels.
