KA75290ZTA

Supervisors Overview

The KA75290ZTA is a voltage detector manufactured by onsemi, designed for monitoring power supply levels. It features a fixed threshold voltage of 2.9V and operates within a maximum supply voltage range of 15V. The device provides an open collector or drain output type and does not include manual reset or watchdog timer functionalities. It is housed in a TO-92-3 through-hole package and supports a wide operating temperature range from -25°C to +85°C.

Supervisors Feature Summary

• Monitors single input voltage against a fixed threshold
• Provides active-low open collector/drain output signal
• Operates without manual reset or watchdog timer functions

Supervisors Applications

• Power supply supervision in embedded systems
• Microprocessor reset circuit generation
• Battery voltage monitoring applications

Supervisors Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm package compatibility with PCB footprint. Check end-of-life status as this part may be discontinued. Ensure thermal management meets specified operating limits. Validate supply chain sources for quality assurance.

Supervisors Selection Notes

Select this component when a fixed 2.9V threshold is required for voltage supervision. Consider the TO-92-3 package for through-hole mounting constraints. Evaluate if open-drain output suits the system logic levels. Assess whether additional features like watchdogs are unnecessary for the design.

Supervisors Part Context

This component belongs to the KA75330Z series of voltage detectors. It shares similar architectural characteristics with other parts in the family, differing primarily in threshold voltage settings. The series is designed for basic power monitoring tasks in consumer and industrial electronics.
