DS1833-10

Supervisors Overview

The DS1833-10 is a voltage supervisory circuit from the EconoReset series, designed for simple reset and power-on reset applications. It features a fixed threshold voltage of 4.375V with a 10% tolerance. The device operates within a supply voltage range of 1.2V to 5.5V and draws a typical operating current of 50 µA. It provides an active-high output in a push-pull configuration. The component supports manual reset functionality and includes power-fail detection capabilities. It is housed in a TO-92-3 package suitable for through-hole mounting and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides active-high reset signal via push-pull output stage
• Includes manual reset input for system control
• Detects power failures with dedicated output indication
• Operates with low quiescent current consumption

Supervisors Applications

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

Supervisors Procurement Notes

Verify RoHS compliance status as records indicate non-compliance for some variants. Confirm availability since the product lifecycle status is listed as obsolete or end-of-life by the manufacturer. Check specific suffixes for packaging differences such as bulk versus tape and reel options. Ensure the correct threshold voltage variant matches the design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.375V threshold is required for single-channel voltage monitoring. Choose the TO-92-3 package for through-hole assembly needs. Consider the active-high output polarity if interfacing with logic families requiring high-level reset signals. Verify that the 50 µA supply current meets the low-power constraints of the target application.
