Description and Introduction

Switched-Capacitor Voltage Inverters The MAX828EUK-T is a voltage detector manufactured by Maxim Integrated.  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX828EUK-T  
- **Type:** Voltage Detector / Supervisor  
- **Output Type:** Active-Low, Push-Pull  
- **Number of Channels:** 1  
- **Threshold Voltage Options:** Factory-Set (e.g., 2.32V, 2.63V, 2.93V, 3.08V, etc.)  
- **Accuracy:** ±1.5% (typical)  
- **Supply Voltage Range:** 1V to 5.5V  
- **Quiescent Current:** 5µA (typical)

- **Package:** SOT23-5  

### **Descriptions:**  
The MAX828EUK-T is a low-power voltage detector designed to monitor power supply voltages in portable and battery-powered applications. It asserts a reset signal when the supply voltage drops below a preset threshold, ensuring proper system operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- Ultra-low quiescent current (5µA typical)  
- Precision voltage monitoring (±1.5% accuracy)  
- No external components required  
- Push-pull active-low reset output  
- Wide supply voltage range (1V to 5.5V)  
- Small SOT23-5 package  
- Industrial temperature range (-40°C to +85°C)  

This device is commonly used in microprocessors, embedded systems, and battery-powered devices for reliable power monitoring.

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 current rating; widely available and directly replaces the MAX828 in inverting applications.
  • ICL7660ACBAZA --: Classic CMOS voltage converter that inverts or doubles supply voltage, functionally equivalent to the MAX828 charge pump with proven reliability.
  • TC7660EOA --: Charge-pump voltage converter in SOIC-8 offering the same inversion function and comparable switching frequency, suitable as a drop-in functional substitute.
  • LTC1144CS8#PBF --: Switched-capacitor voltage inverter with similar topology and supply range; suitable when slightly different package and higher current are acceptable.
