Description and Introduction

200 ms, power-supply sequencer The MAX6819UT-T is a manufacturer part from Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX6819UT-T  
- **Type:** Single/Dual/Triple-Input, µP-Reset Circuits with Debounced Switch Input  
- **Package:** SOT-23-6  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5% (typical)  
- **Reset Timeout Period:** Adjustable or fixed (depending on variant)  
- **Switch Debounce Time:** Typically 20ms (adjustable via external capacitor)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The MAX6819UT-T is a microprocessor (µP) supervisory circuit with a debounced manual reset input.  
- It monitors system voltage and provides a reset signal to the µP when the voltage falls below a preset threshold.  
- Includes a debounced switch input for manual reset functionality.  
- Designed for low-power applications with a wide operating voltage range.  

### **Features:**
- **Voltage Monitoring:** Monitors VCC and asserts reset when voltage drops below threshold.  
- **Manual Reset Input:** Debounced switch input for manual system reset.  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Adjustable Reset Timeout:** Some variants allow adjustment via external capacitor.  
- **Small Form Factor:** Available in a compact SOT-23-6 package.  
- **High Accuracy:** Tight reset threshold accuracy (±1.5%).  

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

Application Scenarios & Design Considerations

200 ms, power-supply sequencer

Alternative Part Number

  • ADM6819ARZ --: Similar voltage supervisor/monitor function in an SOIC package; Analog Devices is the second source for many Maxim supervisory ICs and offers comparable threshold accuracy.
  • TPS3809L30DBVR --: Low-power voltage supervisor with similar reset threshold and open-drain output, available in a small SOT-23 package; a common cross for Maxim supervisory parts.
  • MCP1316T-30DI/OT --: Voltage supervisor with comparable reset delay and active-low output in SOT-23, suitable as a functional replacement when package and threshold are matched.
  • TPS3700DDCR --: TI voltage supervisor with adjustable threshold and open-drain reset output, suitable drop-in functional replacement.
  • MCP1316T-29FE/OT --: Microchip voltage supervisor in SOT-23 package offering comparable reset and monitoring behavior at lower cost.
