Description and Introduction

Single Supply Voltage Supervisor for 5V Systems with Programmable Time Delay 8-SOIC 0 to 70 The TL7705ACDRE4 is a voltage monitor and reset IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 1.5V to 10V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Quiescent Current:** 90µA (typical)  
- **Output Type:** Active-low reset  

### **Descriptions:**  
The TL7705ACDRE4 is designed to monitor system voltage levels and generate a reset signal when the supply voltage falls below a predefined threshold. It ensures proper system initialization during power-up, power-down, or brownout conditions.  

### **Features:**  
- Precision voltage monitoring  
- Adjustable reset delay via external capacitor  
- Low power consumption  
- Built-in hysteresis for noise immunity  
- Wide operating voltage range  
- Industrial temperature range support  

This device is commonly used in microcontrollers, DSPs, and other digital systems requiring reliable power monitoring.

Application Scenarios & Design Considerations

Single Supply Voltage Supervisor for 5V Systems with Programmable Time Delay 8-SOIC 0 to 70

Alternative Part Number

  • MC34064D-5G --: Single-function supply voltage supervisor in SOIC-8 with active-low reset, functionally similar to the TL7705 reset supervisor and widely available.
  • MAX705CPA --: Microprocessor supervisory circuit with reset output in DIP-8, covers the reset-supervisor role of the TL7705 for many designs.
  • MCP130-450DI/TO --: Voltage supervisor with active-low reset output, simple 3-pin alternative suitable for basic supply monitoring where full TL7705 features are not required.
