NCP302LSN09T1G

NCP302LSN09T1G Description

The NCP302LSN09T1G is a supervisor IC from onsemi, designed to provide reliable voltage monitoring and reset functionality in electronic systems. This 1-channel supervisor IC is packaged in a 5-pin TSOP package, making it suitable for surface-mount applications. With an adjustable reset timeout and active low reset, the NCP302LSN09T1G offers flexibility in system design and operation.

NCP302LSN09T1G Features

• Voltage Monitoring: The NCP302LSN09T1G monitors a single voltage supply, with a threshold voltage of 0.9V. This ensures that the system operates within safe voltage limits and triggers a reset when the supply voltage drops below the threshold.
• Adjustable Reset Timeout: The reset timeout can be adjusted or selected, allowing designers to tailor the reset behavior to their specific application requirements.
• Active Low Reset: The NCP302LSN09T1G provides an active low reset output, which can be used to reset microcontrollers or other system components when the supply voltage drops below the threshold.
• Surface Mount Packaging: The 5-pin TSOP package allows for surface-mount installation, saving space and improving reliability in densely populated PCBs.
• RoHS Compliance: The NCP302LSN09T1G is compliant with the RoHS3 directive, making it suitable for use in environmentally friendly products.
• REACH Unaffected: The device is not affected by the REACH regulation, ensuring continued availability and use in electronic products.

NCP302LSN09T1G Applications
