KA75250ZTA

Supervisors Overview

The KA75250ZTA 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 features an open-drain output and operates within a supply voltage range of 1.8V to 15V. The device detects low battery conditions and provides reset signals for microprocessors. It is available in a TO-92-3 package with through-hole mounting capabilities.

Supervisors Feature Summary

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

Supervisors Applications

• Microprocessor reset circuits
• Low battery detection systems
• Power supply monitoring

Supervisors Procurement Notes

Verify the manufacturer part number KA75250ZTA specifically. Confirm the suffix ZTA indicates the TO-92-3 package and tape/reel or tube packaging as per official datasheets. Check RoHS compliance status and ensure the component matches the specified voltage threshold for your application requirements before procurement.

Supervisors Selection Notes

Select this component when a dedicated voltage detector is required for microprocessor reset or low battery indication. Ensure the input voltage range covers your system's operating voltage. Consider the TO-92-3 package size for through-hole assembly constraints. Verify that the open-drain output configuration suits your logic level requirements.

Supervisors Part Context

The KA75250ZTA belongs to the KA75250/KA75270/KA75290 series of voltage detectors from onsemi (formerly Fairchild Semiconductor). These devices are engineered to detect supply voltage drops below a specific threshold, ensuring reliable system operation by triggering reset signals or indicating low power states to connected microcontrollers.
