Description and Introduction

SUPPLY-VOLTAGE SUPERVISOR The **TL7700CPSRG4** is a **supply voltage supervisor (SVS)** IC manufactured by **Texas Instruments (TI)**.  

### **Specifications:**  
- **Function:** Monitors system supply voltage and provides a reset signal when the voltage falls below a preset threshold.  
- **Reset Threshold Voltage:** Factory set to **4.55V** (typical).  
- **Operating Voltage Range:** **1.5V to 18V**.  
- **Reset Output:** Active-low open-drain output.  
- **Reset Timeout Period:** Adjustable via an external capacitor (default: 100ms with 0.1µF capacitor).  
- **Operating Temperature Range:** **-40°C to +125°C**.  
- **Package:** **8-pin SOIC (PS)**.  
- **Accuracy:** **±2%** on reset threshold.  

### **Descriptions:**  
- Designed for **microprocessor/microcontroller** power monitoring.  
- Ensures proper system reset during power-up, power-down, or brownout conditions.  
- Low quiescent current (typically **170µA**).  

### **Features:**  
- **Adjustable reset delay** via an external capacitor.  
- **Wide operating voltage range** (1.5V to 18V).  
- **Open-drain reset output** for flexibility in interfacing.  
- **High noise immunity** on supply input.  
- **Industrial temperature range** support.  

This device is commonly used in **embedded systems, automotive electronics, and industrial controls** for reliable power management.

Application Scenarios & Design Considerations

SUPPLY-VOLTAGE SUPERVISOR

Alternative Part Number

  • MC34064D-5G --: Single-supply voltage supervisor in SOIC-8 with similar reset threshold and open-drain output, widely available and pin-compatible in function.
  • MAX809SEUR+T --: Low-cost 3-pin voltage supervisor with active-low reset, suitable replacement for basic supply monitoring in compact designs.
  • MCP130-475DI/TO --: Voltage supervisor with fixed 4.75V trip point and active-low reset, offering similar supervisory function in a small package.
  • MC33064D-5G --: Single voltage supervisor in SOIC-8 with similar supply-voltage monitoring function and open-collector reset output, widely used as a drop-in functional replacement.
