Description and Introduction

3 Ch Supervisor with Over Current Detect for Switchmode Power Supplies The TPS3514N is a power supply monitor and reset IC manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** 1.5V to 6.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The TPS3514N monitors the voltage of a power supply and generates a reset signal if the voltage falls below a preset threshold.  
- It ensures proper system initialization by holding the reset signal active until the supply voltage stabilizes.  
- Suitable for microprocessor (µP) and microcontroller (µC) applications requiring power-on reset (POR) functionality.  

### **Features:**  
- **Adjustable or Fixed Reset Timeout:** Configurable via an external capacitor.  
- **Low Quiescent Current:** Typically 10µA, reducing power consumption.  
- **Manual Reset Input:** Allows for external reset triggering.  
- **Open-Drain Reset Output:** Compatible with multiple logic levels.  
- **Wide Supply Voltage Range:** Supports operation from 1.5V to 6.5V.  
- **Power-On Reset (POR) Circuitry:** Ensures reliable system startup.  

This information is based on the manufacturer's datasheet and technical documentation.
