Description and Introduction

UltraLow-Supply Current/Supply-Voltage Supervisory Circuit The TPS3103H20DBVR is a voltage supervisor IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 1.1V to 6.5V  
- **Threshold Voltage Options:** Adjustable or fixed (e.g., 2.93V, 3.08V, etc.)  
- **Reset Timeout Period:** Adjustable or fixed (typ. 200ms)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SOT-23-5 (DBV)  
- **Quiescent Current:** 1.5µA (typ)  
- **Output Type:** Active-low, push-pull  
- **Accuracy:** ±1.5% (typ)  

### **Descriptions:**  
The TPS3103H20DBVR is a low-power voltage supervisor designed to monitor system voltages and provide a reset signal when the voltage falls below a preset threshold. It ensures proper system initialization and shutdown.  

### **Features:**  
- Ultra-low power consumption  
- Precision voltage monitoring  
- Adjustable or factory-set threshold options  
- Manual reset capability (MR pin)  
- Small SOT-23-5 package  
- Wide operating voltage range (1.1V to 6.5V)  
- Suitable for battery-powered and portable applications  

For exact threshold options and detailed electrical characteristics, refer to the official TI datasheet.
