Description and Introduction

Low Power Reset Circuit The STM1816RWX7F is a microprocessor reset circuit manufactured by STMicroelectronics. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 1.0V to 5.5V  
- **Reset Threshold Voltage Options:** Adjustable or fixed (1.6V, 2.2V, 2.7V, 3.0V, 3.3V, 5.0V)  
- **Reset Timeout Period:** 140ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- The STM1816RWX7F is a low-power voltage detector designed to monitor system voltage levels and provide a reset signal to microprocessors or microcontrollers when the voltage falls below a specified threshold.  
- It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Low Quiescent Current:** 1.5µA (typical)  
- **Manual Reset Input (MR):** Allows external reset triggering  
- **Open-Drain Reset Output:** Active-low (RESET)  
- **Wide Operating Voltage Range:** Supports 1.0V to 5.5V systems  
- **High Accuracy Threshold Voltage:** ±1.5% tolerance  
- **Power-On Reset (POR) Functionality:** Ensures proper startup  
- **Small Form Factor:** SOT-23-5 package for space-constrained applications  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official STMicroelectronics documentation.
