NCP803SN293D1T1G Description

Short technical summary and product information.

The NCP803SN293D1T1G from On Semiconductor is a cost-effective microprocessor reset monitor designed to ensure system stability. It features a precision voltage monitor for a 2.93V supply, providing a reset signal to the host processor when VCC falls below the threshold.

 

This supervisor IC offers an active-low, open-drain RESET output that remains asserted for a minimum timeout period of 1ms 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 device operates over a wide temperature range of -40°C to 105°C.

 

Packaged in a compact SOT-23-3 (TO-236-3) surface-mount package, the NCP803SN293D1T1G is suitable for battery-powered applications and critical microprocessor power supply monitoring in embedded systems and computers.

 

Key electrical characteristics include a single voltage monitoring channel with a 2.93V threshold and an active-low reset output. The device boasts low supply current, making it ideal for power-sensitive designs.
