Description and Introduction

1.67 V, 140 ms, SC70, single/dual low-voltage, low-power mP reset circuit The MAX6383XR17D3-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX6383XR17D3-T  
- **Type:** Voltage Monitor/Supervisory Circuit  
- **Output Type:** Active-Low, Push-Pull  
- **Reset Threshold Voltage:** 1.7V (Fixed)  
- **Reset Timeout Period:** 140ms (Minimum)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5μA (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-3  

### **Descriptions:**
The MAX6383XR17D3-T is a low-power microprocessor reset circuit designed to monitor system voltage levels. It asserts a reset signal when the supply voltage drops below the preset threshold (1.7V), ensuring proper system initialization. It is commonly used in battery-powered and portable applications where reliable voltage monitoring is critical.

### **Features:**
- **Fixed Threshold Voltage:** 1.7V (±1.5% accuracy)  
- **Low Power Consumption:** 5μA typical supply current  
- **Guaranteed Reset Valid Down to VCC = 1V**  
- **No External Components Required**  
- **Push-Pull RESET Output (Active-Low)**  
- **140ms Minimum Reset Pulse Width**  
- **Small SOT-23-3 Package**  
- **Wide Operating Voltage Range (1.2V to 5.5V)**  

This device is ideal for applications requiring reliable power-on reset and brownout detection, such as embedded systems, IoT devices, and battery-operated electronics.

Application Scenarios & Design Considerations

1.67 V, 140 ms, SC70, single/dual low-voltage, low-power mP reset circuit

Alternative Part Number

  • TPS3839G18DBZT --: Ultra-low-power voltage supervisor with 1.8V threshold in SOT-23, functionally similar to the MAX6383 reset supervisor family.
  • MCP1316T-17CE/OT --: Voltage detector/supervisor with 1.7V trip point and open-drain reset output, comparable function and small package.
  • APX803S-17SA-7 --: Low-cost voltage supervisor with 1.7V threshold and reset output, suitable drop-in functional replacement in SOT-23.
