Description and Introduction

Open-Drain SOT レP Reset Circuit The MAX6315US29D3-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Voltage Monitor/Supervisory Circuit  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Voltages Monitored:** 1  
- **Threshold Voltage:** 2.93V (Adjustable variants available in the series)  
- **Reset Timeout Period:** 140ms (Min), 280ms (Typ)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5µA (Typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**
The MAX6315US29D3-T is a low-power voltage monitor designed to ensure proper system operation by monitoring the power supply voltage. It asserts a reset signal when the supply voltage drops below the preset threshold (2.93V in this case), ensuring the μP or microcontroller remains in a known state during power-up, power-down, or brownout conditions.

### **Features:**
- **Low Power Consumption:** Only 5µA typical supply current.  
- **Precision Voltage Monitoring:** Accurate threshold detection with ±1.5% tolerance.  
- **Manual Reset Input:** Allows external pushbutton reset control (not available in all variants).  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V.  
- **Small Form Factor:** Available in a compact SOT-23-3 package.  
- **No External Components Required:** Simplifies circuit design.  

This device is commonly used in embedded systems, portable electronics, and industrial applications requiring reliable power monitoring.  

(Note: The MAX6315 series includes variants with different threshold voltages and features; ensure the exact part number matches the required specifications.)
