Description
The RN5VD Series is a voltage detector IC with output delay functions and high detector threshold accuracy. It is designed with ultra-low supply current using CMOS process technology. This IC can operate at an extremely low voltage and is commonly used for system reset applications.
Each IC in the RN5VD Series is composed of a voltage reference unit, a comparator, resistors for voltage detection, an output driver, a hysteresis circuit, and an output delay generator. The detector threshold is fixed with high accuracy and does not require any adjustment.
These ICs can be operated by a lower voltage compared to the R×5VL Series and can be driven by a single battery. Two output types are available: Nch open drain type and CMOS type. The ICs are packaged in SOT-23-5 (Mini-mold) package, enabling high density mounting on boards.
