R3118K201C-TR

Supervisors Overview

The R3118K201C-TR is a low voltage detector manufactured by Nisshinbo Micro Devices, designed for monitoring single-input supply voltages. It operates within a power supply range of 1 V to 6 V and features a threshold voltage of 2 V with an accuracy of 1.5%. The device utilizes a CMOS output type and includes a reset delay time of 100 ms. It supports battery backup switching and offers power failure detection capabilities without manual reset or watchdog timer functions. The component consumes 480 nA of operating current and dissipates up to 400 mW of power. It is available in a DFN-PLP-1212-6 package and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary
