Description and Introduction

5V/3.3V/3V Adjustable, High-Efficiency, Low-IQ, Step-Down DC-DC Converters The MAX653ESA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX653ESA+  
- **Type:** Microprocessor (μP) Supervisory Circuit  
- **Package:** 8-SOIC (150mil)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Voltage Options:** Adjustable or Fixed (1.6V, 2.32V, 2.93V, 4.38V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5μA (typ)  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (1.6s timeout)  

### **Descriptions:**
The MAX653ESA+ is a low-power microprocessor supervisory circuit designed to monitor system voltages and provide a reset signal to the μP in case of power failure or brownout conditions. It includes an adjustable or fixed reset threshold, a watchdog timer, and a manual reset input for system control.  

### **Features:**
- **Low Power Consumption:** Only 5μA typical quiescent current.  
- **Adjustable or Fixed Reset Threshold:** Supports multiple voltage monitoring levels.  
- **Watchdog Timer:** Ensures system integrity with a 1.6s timeout.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Wide Operating Voltage Range:** 1.2V to 5.5V.  
- **Industrial Temperature Range:** -40°C to +85°C.  
- **Small Form Factor:** Available in an 8-pin SOIC package.  

This information is strictly based on the manufacturer's datasheet and product specifications.
