Description and Introduction

Low-Noise, Regulated, -2V GaAsFET Bias The **MAX843ISA+** is a precision, low-power, dual-voltage detector manufactured by **MAXIM Integrated**.  

### **Specifications:**  
- **Manufacturer:** MAXIM Integrated  
- **Type:** Voltage Detector  
- **Number of Channels:** 2  
- **Detection Voltage Options:** Factory preset (specific voltages available in the MAX843 series)  
- **Accuracy:** ±1.5% (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 3µA (typical)  
- **Output Type:** Active-Low, Open-Drain  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (ISA)  

### **Descriptions:**  
The MAX843ISA+ is designed to monitor two voltage rails and provide a reset signal if either voltage falls below a preset threshold. It is commonly used in battery-powered and low-voltage systems to ensure proper operation.  

### **Features:**  
- **Low Power Consumption:** 3µA typical supply current  
- **Precision Monitoring:** ±1.5% threshold accuracy  
- **Wide Operating Range:** 1.2V to 5.5V  
- **Open-Drain Outputs:** Allows flexible interfacing  
- **Small Package:** 8-pin SOIC for space-constrained applications  
- **Industrial Temperature Range:** -40°C to +85°C  

For exact preset threshold voltages, refer to the MAXIM datasheet for the specific variant.
