Description and Introduction

Low-Cost, µP Supervisory Circuits The MAX705CSA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX705CSA+  
- **Package:** 8-SOIC (150mil)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (4.40V, 4.65V, or 4.90V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 35μA (typ)  

### **Descriptions:**  
The MAX705CSA+ is a low-power microprocessor supervisory circuit designed to monitor power supply voltages and provide a reset signal to the μP during power-up, power-down, or brownout conditions. It ensures reliable system operation by preventing code execution errors during unstable power conditions.  

### **Features:**  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Power-On Reset (POR):** Guarantees a valid reset signal at power-up.  
- **Low Quiescent Current:** Consumes minimal power (35μA typ).  
- **Watchdog Timer:** Monitors μP activity and triggers reset if software fails.  
- **Adjustable or Fixed Reset Threshold:** Supports multiple voltage monitoring options.  
- **Space-Saving Package:** Available in an 8-pin SOIC package.  

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