NCP803SN263T1G Description

Short technical summary and product information.

The NCP803SN263T1G is a cost-effective system supervisor circuit from On Semiconductor, designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. This device features a precision monitoring voltage of 2.63V and an active-low, open-drain reset output.

 

The reset output is guaranteed to remain active for a minimum timeout period of 140ms after VCC rises above the reset threshold. It is optimized to reject fast transient glitches on the VCC line and requires no external components. The operating temperature range is -40°C to 105°C.

 

This supervisor IC is available in a compact SOT-23-3 (TO-236) surface-mount package, making it suitable for space-constrained applications. Its low supply current also makes it ideal for battery-powered equipment.

 

Typical applications include computers, embedded systems, battery-powered equipment, and critical microprocessor power supply monitoring.
