Description and Introduction

Switched-Capacitor Voltage Inverters The **MAX829EUK** is a voltage detector (supervisor) IC manufactured by **Maxim Integrated** (now part of **Analog Devices**). Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
- **ON Semiconductor (ON)** does not manufacture the MAX829EUK. It is produced by **Maxim Integrated** (now part of Analog Devices).

### **Specifications:**  
- **Function:** Voltage Monitor/Supervisor  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Channels:** 1  
- **Threshold Voltage Options:** Factory-Set (e.g., 2.63V, 2.93V, 3.08V, 4.38V, etc.)  
- **Accuracy:** ±1.5% (typical)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Quiescent Current:** 5µA (typical)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (min. 1ms)  
- **Package:** SOT23-5  

### **Descriptions:**  
- The MAX829EUK monitors system voltage and provides a reset signal to the microprocessor when the voltage falls below a preset threshold.  
- It ensures proper system initialization and prevents data corruption during power-up/down.  
- The device features a manual reset input for external triggering.  

### **Features:**  
- Low quiescent current (5µA) for power-sensitive applications.  
- Push-pull reset output (no external pull-up resistor needed).  
- Wide operating voltage range (1.2V to 5.5V).  
- Precision voltage monitoring (±1.5% accuracy).  
- Available in a compact SOT23-5 package.  
- No external components required for fixed-delay versions.  

For exact threshold options and detailed electrical characteristics, refer to the **Maxim Integrated (Analog Devices) datasheet**.

Application Scenarios & Design Considerations

Switched-Capacitor Voltage Inverters

Alternative Part Number

  • LM2662M/NOPB --: Switched-capacitor voltage inverter in SOT-23-5, pin-compatible function and similar 200 mA output; widely available and a common drop-in for MAX829 applications.
  • ICL7660ACBAZA --: Classic CMOS voltage converter/inverter with the same inverting function and SOIC-8 package; well-established alternative when board layout allows a slightly different footprint.
  • TC7660EOA --: Charge-pump voltage inverter functionally equivalent to the MAX829 family, low cost and readily stocked; suitable for low-current inverting supply rails.
  • LM2662M --: Switched-capacitor voltage inverter in SOT-23-5, functionally equivalent to the MAX829 charge pump inverter with similar switching frequency and current capability.
  • ICL7660 --: Classic CMOS voltage converter/inverter that performs the same charge-pump inversion function; widely available and a common drop-in for MAX829-type inverters.
  • TC7660 --: Charge-pump voltage inverter equivalent to the 7660 family, offering similar inversion performance and a cost-effective alternative to the MAX829EUK.
