Description and Introduction

3.0V or 3.3V microprocessor supervisory circuit. Reset threshold 2.625V. Active-low reset. Manual reset input. Backup-battery switch. Power-fail threshold accuracy +-4%. Power-fail comparator. Reset window +-75mV **Manufacturer:** Maxim Integrated (now part of Analog Devices)  

**Part Number:** MAX704RESA  

### **Specifications:**  
- **Type:** Low-Voltage, Low-Power, 3-Pin μP Reset Circuits  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (over temperature)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (140ms min.)  
- **Quiescent Current:** 5μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (150mil)  

### **Descriptions:**  
The MAX704RESA is a microprocessor (μP) supervisory circuit designed to monitor system power supply voltages. It provides a reset signal to the μP during power-up, power-down, or brownout conditions, ensuring proper system operation.  

### **Features:**  
- Precision voltage monitoring for 1.2V to 5.5V systems  
- Low quiescent current (5μA typical)  
- Manual reset input (MR) for external control  
- Adjustable or fixed reset timeout  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required for fixed threshold versions  
- Space-saving 8-pin SOIC package  

(Note: The MAX704RESA is obsolete; refer to Analog Devices for replacement options.)
