Description and Introduction

5V Supervisor with Battery Switchover The STM819MM6F is a microprocessor supervisory circuit from STMicroelectronics. Here are the factual details from Ic-phoenix technical data files:  

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Type:** Voltage Monitor & Reset IC  
- **Reset Threshold Options:** Adjustable or fixed (specific voltage thresholds available in datasheet)  
- **Reset Timeout Period:** Typically 140ms (adjustable in some variants)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Package:** SOT-23-5 (MM6)  
- **Temperature Range:** Industrial (-40°C to +85°C)  
- **Output Type:** Active-low reset (open-drain or push-pull, depending on variant)  
- **Quiescent Current:** Low power consumption (typically a few µA)  

### **Descriptions:**  
- Monitors system voltage and generates a reset signal if the supply voltage drops below a predefined threshold.  
- Ensures proper microcontroller or processor initialization during power-up, power-down, or brownout conditions.  
- Suitable for battery-powered and low-voltage applications.  

### **Features:**  
- Precision voltage monitoring  
- Manual reset input (if available in variant)  
- Low quiescent current for power-sensitive applications  
- Small form factor (SOT-23-5 package)  
- Hysteresis for noise immunity  

For exact specifications (threshold voltages, timing, etc.), refer to the official **STM819MM6F datasheet** from STMicroelectronics.
