Description and Introduction

SUPPLY VOLTAGE SUPERVISORS The TL7700 from Texas Instruments (TI) is a power supply supervisor and reset IC. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** 1.8V to 18V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 150µA (typical)  
- **Reset Timeout Period:** Adjustable via external capacitor (typically 100ms with 1µF)  
- **Output Type:** Active-low or active-high reset (depending on variant)  
- **Package Options:** SOIC-8, PDIP-8  

### **Descriptions:**  
- The TL7700 is a precision voltage monitor designed to detect power supply failures and generate a reset signal for microprocessors or digital systems.  
- It ensures proper system initialization by holding the reset signal until the supply voltage stabilizes.  
- The reset threshold is factory-trimmed for accuracy.  

### **Features:**  
- **Wide Operating Voltage Range:** Supports monitoring from 1.8V to 18V.  
- **Adjustable Reset Delay:** External capacitor allows customization of reset timeout.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **High Accuracy:** Tight tolerance (±1.5%) on reset threshold.  
- **Reliable Reset Output:** Ensures stable system operation during power-up/down.  
- **Available in Standard Packages:** SOIC-8 and PDIP-8 for easy integration.

Application Scenarios & Design Considerations

SUPPLY VOLTAGE SUPERVISORS

Alternative Part Number

  • MC34064 --: Single-function supply voltage supervisor with similar reset threshold behavior, widely available and pin-compatible in many designs.
  • MAX809 --: Low-cost 3-pin voltage supervisor with active-low reset output, suitable replacement for basic supply monitoring functions.
  • MCP130 --: Voltage supervisor with open-drain reset output and similar threshold options, good alternative when a simple reset IC is needed.
