CAT809ZSDI-T3

Supervisors Overview

The CAT809ZSDI-T3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single-input power rails. It features a push-pull output type and operates within a supply voltage range of 1.2 V to 5.5 V. The device has a threshold voltage of 2.32 V and an overvoltage threshold of 2.35 V. It includes a reset delay time of 240 ms and consumes a working supply current of 8 uA. The component is housed in an SC-70-3 package and supports surface mount installation. It functions without manual reset, watchdog timer, or battery backup switch capabilities.

Supervisors Feature Summary

• Provides voltage supervision with a push-pull output interface for reliable signal transmission.
• Operates with low power consumption suitable for battery-powered applications.
• Features a compact SC-70-3 package for space-constrained designs.

Supervisors Applications

• Microprocessor power monitoring
• Voltage supervision in embedded systems
• Portable electronic devices

Supervisors Procurement Notes

Verify the specific manufacturing lot and date code upon order confirmation, as this part number may be subject to discontinuation notices from the manufacturer. Ensure that the SC-70-3 package dimensions align with your PCB footprint requirements. Confirm RoHS compliance status through official documentation before finalizing procurement, as regulatory updates can occur. Cross-reference the supplier's datasheet version to ensure all electrical parameters match your design specifications.

Supervisors Selection Notes

Select this component when a fixed 2.32 V threshold is required for a single-channel power rail. The push-pull output allows direct interfacing with digital logic without additional pull-up resistors. Consider the 240 ms reset delay to ensure stable system startup. Evaluate the 8 uA quiescent current against total system power budgets. Verify that the 5.5 V maximum operating voltage covers the highest expected supply rail variations.

Supervisors Part Context

This part belongs to the CAT809 series of voltage supervisory circuits from onsemi. The series offers various threshold voltages and package options to suit different monitoring needs. The CAT809ZSDI-T3 specifically targets applications requiring a 2.32 V trip point in a small form factor. It complements other PMIC solutions by providing dedicated reset generation for microprocessors and memory devices.

Supervisors Replacement Considerations

Check for CAT809 variants with similar thresholds if exact availability is limited. Verify pinout compatibility for direct replacement in existing designs. Ensure equivalent electrical characteristics such as reset delay and supply current are maintained.
