Description and Introduction

Microprocessor Supervisory Circuit in 3-Pin SOT23 The SGM803 is a voltage detector (reset IC) manufactured by SGMIC (SG Micro Corp). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 0.7V to 6.0V  
- **Detection Voltage Range:** 1.2V to 5.0V (in 0.1V steps)  
- **Detection Voltage Accuracy:** ±1.5% (typical)  
- **Quiescent Current:** 0.8μA (typical)  
- **Output Configuration:** Push-Pull or Open-Drain (depending on variant)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The SGM803 is a low-power voltage detector designed for monitoring system power supply voltages.  
- It provides a reset signal when the supply voltage drops below a preset threshold.  
- Available in SOT-23 and SC70 packages for space-constrained applications.  

### **Features:**
- **Ultra-Low Power Consumption:** 0.8μA typical quiescent current.  
- **High Accuracy:** ±1.5% detection voltage tolerance.  
- **Wide Operating Voltage Range:** Supports 0.7V to 6.0V.  
- **Adjustable Detection Voltage:** Available in fixed thresholds from 1.2V to 5.0V.  
- **Multiple Output Options:** Push-Pull (SGM803) or Open-Drain (SGM803-OD).  
- **Small Package Options:** SOT-23-3 and SC70-3.
