Description and Introduction

Switched-Capacitor Voltage Inverters The MAX828EUK is a voltage detector manufactured by 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:** MAX828EUK  
- **Package:** SOT-23-5  
- **Type:** Voltage Detector/Supervisor  
- **Detection Voltage Options:** Factory-set (e.g., 2.63V, 2.93V, 3.08V, 4.38V, etc., depending on variant)  
- **Accuracy:** ±1.5% (typical)  
- **Operating Voltage Range:** 1V to 5.5V  
- **Quiescent Current:** 5µA (typical)  
- **Output Type:** Active-Low Reset (Open-Drain)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX828EUK is a low-power voltage detector/supervisor IC designed to monitor system voltage levels. It asserts a reset signal when the supply voltage drops below a preset threshold, ensuring proper system initialization. The open-drain output allows flexibility in interfacing with different logic levels.

### **Features:**
- **Low Power Consumption:** 5µA typical quiescent current.  
- **Precision Voltage Monitoring:** ±1.5% threshold accuracy.  
- **Wide Operating Voltage Range:** 1V to 5.5V.  
- **Open-Drain Reset Output:** Compatible with multiple logic levels.  
- **Factory-Programmed Thresholds:** No external components needed.  
- **Small Form Factor:** SOT-23-5 package for space-constrained applications.  
- **Temperature Stability:** Operates reliably across industrial temperature ranges.  

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

Application Scenarios & Design Considerations

Switched-Capacitor Voltage Inverters

Alternative Part Number

  • LM2662M --: Switched-capacitor voltage inverter in SOT-23-5, functionally equivalent to the MAX828 charge pump inverter with similar input range and output current.
  • ICL7660 --: Classic CMOS voltage converter/inverter that performs the same charge-pump inversion function; widely available and a common drop-in functional substitute.
  • TC7660 --: CMOS charge pump voltage converter offering the same inverting function as the MAX828, suitable for low-current negative supply generation.
