The RN5VL32AA-TR is a voltage detector IC manufactured by Ricoh Electronic Devices Co., LTD. It is a highly accurate and low-consumption voltage detector, designed to monitor the power supply voltage of electronic devices. When the supply voltage drops below a pre-set detection voltage, it outputs a reset signal, preventing malfunctioning of the system and protecting valuable data.

Applications

• Microcontroller reset: Used to reliably reset microcontrollers during power-up or voltage drops, preventing erratic behavior.
• CPU reset: Provides reset functionality for CPUs in various electronic devices.
• Power supply monitoring: Monitors power supply voltages to ensure stable operation of electronic circuits.
• Battery-powered equipment: Detects low battery voltage and prevents deep discharge, extending battery life.
• Memory protection: Prevents data corruption in memory devices by initiating a reset during voltage drops.

Features

• High-accuracy detection voltage: The detection voltage is very precise, typically 3.2V with a very low tolerance, ensuring accurate voltage monitoring.
• Ultra-low current consumption: Minimizes power consumption, making it suitable for battery-powered devices. The typical current consumption is extremely low, usually in the microampere range.
• Built-in hysteresis: Prevents output oscillation near the detection threshold, providing a stable and reliable reset signal.
• Open drain output: The output is an N-channel open drain, which allows for flexible interface with microcontrollers and other logic circuits.
• Small package: Available in a small SOT-23 or similar package, saving valuable board space.
