DS1233Z-5/T&R

Supervisors Overview

The DS1233Z-5+T&R is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, belonging to the EconoReset series. It features a single monitored input with an open-drain or collector-open output type and operates within a supply voltage range of 1.2 V to 5.5 V. The device provides a minimum reset delay time of 250 ms and includes power-fail detection capabilities without manual reset or watchdog timer functions. Designed for surface-mount installation in SOT-223 packages, it maintains accuracy within 5% across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low reset signal generation based on monitored supply voltage levels
• Integrates power-fail detection to identify voltage anomalies during operation
• Features low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor system supervision
• Battery-operated electronic devices
• Portable instrumentation monitoring

Supervisors Procurement Notes

Verify the specific package variant against the datasheet, as sourcing data indicates potential discrepancies between SOT-223-3 and SOT-223-4 designations for this part number. Confirm RoHS compliance status directly with the manufacturer before procurement. Ensure the ordering suffix matches the required tape-and-reel configuration for automated assembly processes.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisory solution is required for single-rail systems. It is appropriate for designs needing basic power-fail indication alongside standard reset generation. Consider alternative packages if board space constraints differ from the SOT-223 footprint requirements.

Supervisors Part Context

This component belongs to the DS1233 family of voltage supervisors designed for economical system protection. The Z-series designation typically denotes surface-mount packaging variants within the broader product line. These devices are engineered to replace older discrete supervisor solutions with integrated monolithic ICs.
