Description and Introduction

Open-Drain SOT レP Reset Circuit The MAX6315US45D3-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor Supervisory Circuit  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Threshold Voltage:** 4.5V (Adjustable)  
- **Reset Timeout Period:** 140ms (Min), 280ms (Typ), 560ms (Max)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 6μA (Typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-3  

### **Descriptions:**
The MAX6315US45D3-T monitors the power supply voltage of a microprocessor or microcontroller. It asserts a reset signal when the supply voltage drops below a preset threshold (4.5V in this case) and keeps the reset signal active for a fixed timeout period after the voltage returns to a valid level.  

### **Features:**
- **Low Power Consumption:** Only 6μA typical quiescent current.  
- **Precision Voltage Monitoring:** Ensures reliable system operation.  
- **Manual Reset Input:** Allows external reset control.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V.  
- **Small Form Factor:** Available in a compact SOT23-3 package.  
- **No External Components Required:** Simplifies design.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset even at low voltages.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications where reliable power monitoring is critical.
