Description and Introduction

4-Pin Reset Monitors The TC1270RERCTR is a microprocessor supervisory circuit manufactured by Microchip Technology. Below are the factual details about this component:  

### **Specifications:**  
- **Manufacturer:** Microchip  
- **Part Number:** TC1270RERCTR  
- **Type:** Voltage Supervisor  
- **Package:** SOT-23-5  
- **Operating Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Accuracy:** ±2.5%  
- **Reset Timeout Period:** 140ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5µA (typical)  

### **Descriptions:**  
- The TC1270RERCTR is a low-power microprocessor reset monitor designed to ensure proper system operation during power-up and brownout conditions.  
- It provides a reset signal to the microprocessor when the supply voltage drops below a preset threshold.  
- The device features a manual reset input for external system control.  

### **Features:**  
- Precision voltage monitoring for 1.8V, 2.5V, 3.0V, 3.3V, and 5.0V systems  
- Low quiescent current for power-sensitive applications  
- Push-pull RESET output (active-low)  
- Manual reset input for external control  
- Immune to short voltage transients  
- Guaranteed reset output down to VCC = 1.0V
