CAT803SSDI-GT3

Supervisors Overview

The CAT803SSDI-GT3 is a single-channel voltage supervisory circuit manufactured by onsemi, designed for monitoring power supply integrity in electronic systems. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.93 V with an overvoltage threshold of 2.96 V. The device provides an active low, open-drain output signal and includes a reset delay time of 20 us. It consumes a typical operating supply current of 6 uA and is housed in a compact SC-70-3 surface-mount package. The component supports an industrial temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides simple reset or power-on-reset functionality via an open-drain output.

Supervisors Applications

• Monitoring microprocessor and microcontroller supply voltages.

Supervisors Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm availability through authorized distributors or secondary markets. Ensure that any replacement parts maintain compatibility with the required threshold voltage and package dimensions. Check for RoHS compliance documentation if environmental regulations apply to the target application.

Supervisors Selection Notes

Select this component when a low-power, single-supervisor solution is required for voltages near 3 V. The SC-70-3 package suits space-constrained layouts. Consider the 20 us reset delay and open-drain output characteristics during circuit design. Evaluate alternative parts if manual reset or watchdog timer capabilities are necessary for the system architecture.

Supervisors Part Context

This part belongs to the CAT803 series of voltage supervisors from onsemi. The series offers various threshold voltages and packages to support different power management needs. The CAT803SSDI-GT3 specifically targets applications requiring a fixed 2.93 V threshold in a small form factor.
