Description and Introduction

±1% Accuracy, Low-Power, +3V and +5V µP Supervisory Circuits The MAX815TESA+T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Manual Reset Input:** Active-low (MR)  
- **Power-On Reset (POR) Detection:** Yes  
- **Watchdog Timer:** 1.6s timeout (typ)  

### **Descriptions:**  
The MAX815TESA+T monitors system voltage and provides a reset signal to the microprocessor when the supply voltage drops below a preset threshold. It includes a watchdog timer to detect software lockups and a manual reset input for user-initiated resets.  

### **Features:**  
- Precision voltage monitoring  
- Low quiescent current (35μA typ)  
- Guaranteed reset output valid down to VCC = 1V  
- Watchdog timer with 1.6s timeout  
- Manual reset input  
- No external components required for fixed threshold versions  
- Space-saving 8-pin SOIC package
