KA75450MTF

Supervisors Overview

The KA75450MTF is a voltage detector manufactured by onsemi, designed to prevent system errors caused by supply voltage dropping below normal levels during power-on or instantaneous power-off events. This component provides a reset function for low-voltage microprocessors and includes low-battery checking capabilities. It operates within a standard commercial temperature range and utilizes surface-mount packaging for integration into electronic circuits requiring reliable voltage supervision.

Supervisors Feature Summary

• Detects against 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 detection systems
• Battery-powered device monitoring

Supervisors Procurement Notes

Verify the manufacturer designation carefully, as this part number was originally associated with Fairchild Semiconductor before its acquisition by onsemi. Ensure the specific suffix matches the required package and tape/reel configuration for your assembly line. Cross-reference with current onsemi catalogs to confirm active status and updated documentation availability.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor is needed for microprocessor reset logic. It is suitable for applications requiring detection of undervoltage conditions without complex external components. Consider the operating voltage range and output type compatibility with the target logic family before finalizing the design.

Supervisors Part Context

This device belongs to the KA75xx series of voltage detectors, which are widely used for supervising power rails in digital systems. The series offers various threshold voltages to accommodate different logic families and battery chemistries, providing a standardized solution for power management reliability.

Supervisors Replacement Considerations

Compatible alternatives include NJM2405 from New Japan Radio and TC54 from TelCom Semiconductor or Microchip Technology. These parts serve similar voltage detection functions but may differ in pinout, threshold accuracy, or package dimensions.
