Description and Introduction

Single SVS For 9v Systems W/Pgmmable Time Delay **Manufacturer:** Texas Instruments (TI) / STMicroelectronics (ST)  

**Part Number:** TL7709ACP  

### **Specifications:**  
- **Supply Voltage Range:** 4.5V to 18V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Operating Temperature Range:** -40°C to +85°C (industrial grade)  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Output Type:** Active-low reset signal (open-drain or push-pull, depending on variant)  
- **Quiescent Current:** Typically 350µA  

### **Descriptions:**  
The TL7709ACP is a precision voltage supervisor/monitor IC designed to provide a system reset in the event of power supply anomalies. It monitors the supply voltage and generates a reset signal when the voltage falls below a preset threshold, ensuring proper system initialization.  

### **Features:**  
- Adjustable reset threshold via external resistors  
- Manual reset input capability  
- Low power consumption  
- Guaranteed reset output valid down to VCC = 1V  
- Built-in hysteresis for noise immunity  
- Suitable for microprocessor and microcontroller-based systems  

(Note: Some specifications may vary slightly between TI and ST versions. Always refer to the official datasheet for exact details.)

Application Scenarios & Design Considerations

Single SVS For 9v Systems W/Pgmmable Time Delay

Alternative Part Number

  • MC34064P-5 --: Single-supply voltage supervisor in a DIP-8 package with similar reset threshold and open-drain output, a common drop-in for TL7709-style supply monitoring.
  • MAX809SEUR+T --: Compact 3-pin reset supervisor with active-low reset and comparable threshold, suitable when board space is limited and DIP is not required.
  • MCP130-450DI/TO --: Low-cost voltage supervisor with active-low reset output and similar trip voltage, usable as a functional replacement in many reset circuits.
