Description and Introduction

Single Supply Voltage Supervisor ror 5V Systems with Programmable Time Delay The TL7705BCP is a voltage supervisor IC manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on the factual information:

### **Specifications:**  
- **Supply Voltage Range:** 1.5V to 18V  
- **Reset Threshold Accuracy:** ±1% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 60µA (typical)  
- **Reset Time Delay:** Adjustable via external capacitor  
- **Output Type:** Active-low open-drain reset output  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The TL7705BCP is a precision voltage supervisor/monitor designed to monitor system power supply voltages. It provides a reset signal to the microcontroller or processor when the supply voltage falls below a preset threshold, ensuring proper system initialization. The reset time delay can be adjusted using an external capacitor.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset operation with ±1% threshold accuracy.  
- **Wide Operating Voltage Range:** Supports monitoring from 1.5V up to 18V.  
- **Low Power Consumption:** Typical quiescent current of 60µA.  
- **Adjustable Reset Delay:** External capacitor allows customization of reset pulse width.  
- **Open-Drain Reset Output:** Compatible with multiple logic levels.  
- **Robust Design:** Suitable for industrial and automotive applications with a wide temperature range.  

This information is based on TI's official documentation for the TL7705BCP.
