Description and Introduction

Supply-Voltage Supervisor And Precision Voltage Detector The TL7757CPK is a power supply monitor IC manufactured by Texas Instruments (TEXAS). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range:** 4.5V to 40V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** Active-Low Reset  
- **Reset Timeout Period:** Adjustable (typically 200ms)  
- **Package Type:** PK (TO-92-3)  

### **Descriptions:**
- The TL7757CPK is a voltage supervisor/monitor IC designed to ensure proper system reset during power-up, power-down, or brownout conditions.  
- It monitors the supply voltage and generates a reset signal when the voltage falls below a preset threshold.  
- The device features a manual reset input for additional system control.  

### **Features:**
- **Wide Operating Voltage Range (4.5V–40V)**  
- **Precision Voltage Monitoring**  
- **Adjustable Reset Timeout**  
- **Manual Reset Capability**  
- **Low Quiescent Current**  
- **TO-92 Package for Easy Integration**  

This IC is commonly used in industrial, automotive, and embedded systems for reliable power management.
