KA75450ZTA

Supervisors Overview

The KA75450ZTA is a voltage detector manufactured by onsemi, designed to monitor supply voltages and prevent system errors during power-on or instantaneous power-off events. It functions as a reset circuit for low-voltage microprocessors and includes low-battery checking capabilities. The component operates within a temperature range of -25°C to +85°C and utilizes a TO-92-3 through-hole package with three pins.

Supervisors Feature Summary

• Detects error operations at power-on and power-off
• Provides resetting function for low-voltage microprocessors
• Checks for low battery conditions

Supervisors Applications

• Microprocessor reset circuits
• Low-voltage monitoring systems
• Battery-powered device supervision

Supervisors Procurement Notes

Verify the specific suffix 'ZTA' against official onsemi documentation to confirm packaging details, as datasheets may list generic variants like 'Z'. Ensure compatibility with required operating temperatures and package types before ordering. Confirm current availability status directly with authorized distributors.

Supervisors Selection Notes

Select this component when a simple, single-channel voltage supervisor is needed for basic power management tasks. It is suitable for applications requiring reliable detection of under-voltage conditions without complex configuration options. Consider thermal performance and package constraints for PCB layout.

Supervisors Part Context

This part belongs to the KA75 series of voltage detectors from onsemi (formerly Fairchild Semiconductor). These devices are widely used in consumer electronics and industrial equipment for basic power supervision. The series offers various threshold voltages to suit different logic families and power rails.

Supervisors Replacement Considerations

Compatible alternatives include KA75330ZTA, KA75420ZBU, and KA75250Z. Verify that the replacement part matches the required threshold voltage and output type (open collector/drain) for direct substitution.
