Description and Introduction

320mW; I(o): 20mA; V(cc): -0.3 to +7.0V; reset circuit The STM811SW16F is a microprocessor supervisory circuit manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Typically 140ms (adjustable with external capacitor)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The STM811SW16F monitors the power supply voltage of a microprocessor or microcontroller.  
- It asserts a reset signal when VCC falls below a preset threshold, ensuring proper system initialization.  
- It is designed for low-power applications and provides reliable power-on reset functionality.  

### **Features:**
- **Low Quiescent Current:** Typically 5µA (ideal for battery-powered applications).  
- **Manual Reset Input:** Allows external push-button reset control.  
- **Power-Fail Comparator:** Provides early warning of power failure.  
- **Guaranteed Reset Valid Down to VCC = 1V.**  
- **Hysteresis:** Ensures noise immunity during voltage transitions.  

This device is commonly used in embedded systems, industrial controls, and consumer electronics for reliable power management.
