DS1233-10/T&R

Supervisors Overview

The DS1233-10/T&R is a voltage supervisory circuit from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It provides a reset signal for single-supply microprocessors and logic systems. The device features an open-drain or open-collector output that asserts low when the supply voltage drops below a threshold of 4.625 V. It operates within a supply voltage range of 1.2 V to 5.5 V and includes power-fail detection. The component is housed in a TO-92-3 package with through-hole mounting and supports an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors supply voltage and generates a reset signal upon undervoltage conditions
• Includes power-fail output to warn of impending system shutdown
• Offers configurable active-low reset output via open-drain or open-collector configuration

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Power management supervision for handheld devices
• Industrial control systems requiring voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix designation against official datasheets to confirm electrical characteristics, as variations exist within the family. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the TO-92-3 through-hole package matches your PCB layout requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a simple, low-cost voltage monitor is required for single-supply applications. The DS1233-10 variant is suitable for systems needing a 4.625 V threshold. Consider the TO-92-3 package if through-hole assembly is preferred over surface-mount options. Verify that the open-drain/open-collector output type aligns with the input requirements of the downstream logic or microcontroller.

Supervisors Part Context

This part belongs to the Maxim Integrated EconoReset family, designed for cost-sensitive applications. It simplifies power management by integrating reset generation and power-fail detection into a single small package. The series is widely used in consumer electronics and industrial equipment where reliable power supervision is critical for system stability.

Supervisors Replacement Considerations

Compatible substitutes include other EconoReset variants such as the DS1233A-10+ or DS1810/DS1811 series, provided the threshold voltage and output configuration match the design requirements. Always verify pinout compatibility and thermal performance before substitution.
