CAT863MTBI-GT3

Supervisors Overview

The CAT863MTBI-GT3 is a single-channel voltage supervisor IC manufactured by onsemi. It operates within a supply voltage range of 1.2 V to 5.5 V and features an active low, push-pull output. The device monitors one input with a threshold voltage of 4.38 V and includes a reset delay time of 240 ms. It does not support manual reset or watchdog timer functions. The component is housed in a SOT-23-3 package and supports surface mount installation. It functions without a chip enable signal and has a typical operating supply current of 20 uA.

Supervisors Feature Summary

• Provides fixed voltage supervision for power-on reset applications
• Features active low push-pull output driver
• Operates across a wide supply voltage range from 1.2 V to 5.5 V

Supervisors Applications

• Power-on reset circuits
• Simple reset applications
• Voltage monitoring in embedded systems

Supervisors Procurement Notes

Verify the specific suffix GT3 corresponds to the tape and reel packaging configuration required for your assembly line. Confirm that the SOT-23-3 footprint matches your PCB design constraints. Ensure the 4.38 V threshold aligns with your system's voltage requirements. Check for any RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a fixed 4.38 V threshold is required. It is suitable for designs needing a 240 ms reset delay and active low output. Consider the low operating current of 20 uA for battery-powered applications. Verify compatibility with the 1.2 V minimum supply voltage if using lower voltage rails.

Supervisors Part Context

This part belongs to the CAT809 series of voltage supervisors from onsemi. It shares functional similarities with other devices in the family but is distinguished by its specific threshold and package type. The series is designed for reliable power management in consumer and industrial electronics requiring stable voltage monitoring.
