Description and Introduction

Voltage Supervisor 8-TSSOP -40 to 85 The TL7700CPWRG4 is a power supply monitor and reset IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 1.5V to 10V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TSSOP (PW)  
- **Pin Count:** 8  
- **Reset Timeout Period:** Adjustable via external capacitor  
- **Quiescent Current:** 35µA (typical)  

### **Descriptions:**  
The TL7700CPWRG4 is designed to monitor power supply voltages and generate a reset signal when the voltage falls below a preset threshold. It ensures proper system initialization by holding the reset signal until the supply voltage stabilizes.  

### **Features:**  
- Adjustable reset threshold via external resistors  
- Low power consumption  
- Wide operating voltage range  
- Guaranteed reset output down to VCC = 1V  
- Internal delay timer for reset pulse width  
- Available in a small TSSOP package  

This device is commonly used in microprocessors, embedded systems, and other applications requiring reliable power monitoring.

Application Scenarios & Design Considerations

Voltage Supervisor 8-TSSOP -40 to 85

Alternative Part Number

  • MC33064D-5G --: Single-supply voltage supervisor in SOIC-8 with similar reset threshold and open-drain output, a common drop-in functional equivalent to the TL7700 series.
  • MAX809REUS+T --: Low-cost 3-pin reset supervisor with fixed reset threshold and active-low push-pull output, suitable for replacing TL7700 supply monitoring in many designs.
  • MCP130T-450I/TT --: Voltage supervisor with 4.5V trip point and open-drain reset output in SOT-23, offering a compact alternative when board space is limited.
