KA75270ZTA

Supervisors Overview

The KA75270ZTA is a single-channel voltage supervisor integrated circuit manufactured by onsemi. It provides simple reset and power-on reset functions with an open-drain or open-collector output that asserts active low. The device monitors one input voltage, featuring a threshold range of 2.5 V to 4.5 V, with specific typical values including a 2.55 V under-voltage threshold and a 2.85 V over-voltage threshold. It operates within a supply voltage range of 300 mV to 15 V and consumes 500 uA of working current. The component is housed in a TO-92-3 package, supports surface mount mounting, and functions reliably between -25°C and +85°C ambient temperatures.

Supervisors Procurement Notes

Verify the exact datasheet specifications for the KA75270ZTA variant, as availability may vary by region. Confirm package compatibility with existing PCB footprints. Check for obsolescence status and lead times through authorized distributors. Ensure environmental compliance requirements match project needs. Validate electrical parameters against system design constraints before procurement.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with open-drain output is required. Consider the operating temperature range and supply voltage limits. Evaluate the threshold voltage accuracy for specific application needs. Compare power consumption requirements with other available options. Verify package type suitability for manufacturing processes.

Supervisors Part Context

The KA75270 series includes variants like KA75270MTF and KA75270ZTA, offering similar supervisory functions in different packages. These components are part of onsemi's power management IC portfolio, designed for reliable voltage monitoring in various electronic systems. The ZTA variant specifically utilizes a TO-92-3 package, distinguishing it from surface-mount alternatives in the same family.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the KA75270 family. Verify equivalent electrical characteristics such as threshold voltages and output configurations. Ensure replacement components meet the same environmental and reliability standards. Consult manufacturer documentation for approved cross-reference lists.
