Description and Introduction

3.3V Input to Regulated 5V Output Charge Pumps The MAX682ESA-T is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX682ESA-T  
- **Package:** 8-SOIC (150 mils)  
- **Type:** Microprocessor Supervisor  
- **Supply Voltage (VCC):** 1.2V to 5.5V  
- **Reset Threshold Voltage Options:** Adjustable or Fixed (2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 15μA (typ)  
- **Manual Reset Input:** Yes (Active-low)  
- **Watchdog Timer:** Yes (1.6s timeout)  
- **Output Type:** Active-low, Push-pull  

### **Descriptions:**
- The MAX682ESA-T monitors system voltage and provides a reset signal to the microprocessor if the voltage drops below a preset threshold.  
- It includes a watchdog timer to detect software lock-ups and a manual reset input for user-initiated resets.  
- Designed for low-power applications, it ensures reliable system operation in battery-powered or critical monitoring systems.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures accurate reset triggering.  
- **Low Quiescent Current:** Ideal for battery-operated devices.  
- **Adjustable or Fixed Threshold Options:** Supports various voltage levels.  
- **Watchdog Timer:** Prevents system lock-ups.  
- **Manual Reset Capability:** Allows external reset control.  
- **Wide Operating Voltage Range (1.2V to 5.5V):** Compatible with multiple logic levels.  
- **Industrial Temperature Range:** Suitable for harsh environments.  

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

Application Scenarios & Design Considerations

3.3V Input to Regulated 5V Output Charge Pumps

Alternative Part Number

  • LTC1686CS8#PBF --: Pin-compatible 5V RS-485/RS-422 transceiver in SO-8 with similar function and performance; different series naming makes it easy to distinguish from the source.
  • SN75176BDR --: Widely available industry-standard RS-485 transceiver in SOIC-8, functionally equivalent and a common drop-in alternative.
  • ST485ECDR --: Low-power RS-485/RS-422 transceiver in SO-8 with comparable specifications and good availability as a cost-effective substitute.
  • SP485ECN-L --: Low-power RS-485 transceiver in SOIC-8 with comparable data rate and supply voltage, a common alternate for MAX-series RS-485 parts.
