Description and Introduction

+-1% accuracy, low-power, microprocessor supervisory circuit. Reset trip threshold (min) 4.75V (max) 4.85V, push-pull active-low reset output, push-pull active-high reset output, manual reset, power-fail monitor, low-line detector. The MAX814KCSA 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:** MAX814KCSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Type:** Microprocessor Voltage Monitor/Supervisor  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (e.g., 4.63V, 4.38V, 3.08V, 2.93V, 2.63V, 2.32V)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Quiescent Current:** 12μA (typical)  

### **Descriptions:**  
The MAX814KCSA is a precision voltage monitor designed to ensure proper operation of microprocessors and digital systems. It monitors the power supply voltage and generates a reset signal if the voltage falls below a preset threshold. The device includes a manual reset input and a watchdog timer to enhance system reliability.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset generation during power-up, power-down, and brownout conditions.  
- **Manual Reset Input:** Allows for external system reset via a pushbutton.  
- **Watchdog Timer:** Monitors microprocessor activity; resets the system if the watchdog is not toggled within a set time.  
- **Low Power Consumption:** Typically draws 12μA, making it suitable for battery-powered applications.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures proper reset assertion even at very low voltages.  
- **Available in Multiple Threshold Voltages:** Supports various system voltage requirements.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

+-1% accuracy, low-power, microprocessor supervisory circuit. Reset trip threshold (min) 4.75V (max) 4.85V, push-pull active-low reset output, push-pull active-high reset output, manual reset, power-fail monitor, low-line detector.

Alternative Part Number

  • ADM809LARTZ-REEL --: Pin-compatible microprocessor supervisory circuit with similar reset threshold and active-low reset output, widely available and functionally equivalent.
  • TL7705ACDR --: Classic voltage supervisor IC offering reset generation and watchdog-like supervision, suitable drop-in for many MAX814 applications.
  • MC33064D-5G --: Undervoltage sensing circuit with active-low reset output, low cost and commonly used as an alternative supervisor in similar designs.
  • ADM706TARZ --: Supervisory/monitoring IC with reset and watchdog functions in SOIC-8, functionally similar to the MAX814 supervisor family.
  • TPS3705-33DR --: Voltage supervisor with reset and watchdog in SOIC-8, a common cross-manufacturer substitute for MAX814-type supervisors.
