Description and Introduction

DAC-Controlled Boost Inverter LCD Bias Supply with Internal Switch The MAX686EEE+ is a microprocessor supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Supervisory Circuit  
- **Package:** 16-QSOP  
- **Operating Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** Adjustable (factory-set or externally programmable)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 20µA (typical)  

### **Descriptions:**  
The MAX686EEE+ is a low-power microprocessor supervisor designed to monitor system voltages and provide a reset signal when the voltage falls below a preset threshold. It ensures proper system operation by holding the microprocessor in reset until the supply voltage stabilizes.  

### **Features:**  
- **Low-Power Operation:** Consumes minimal current, making it suitable for battery-powered applications.  
- **Adjustable Reset Timeout:** Can be set via an external capacitor.  
- **Manual Reset Input:** Allows for external reset triggering.  
- **Wide Operating Voltage Range:** Supports 1.8V to 5.5V systems.  
- **High Accuracy Reset Threshold:** Ensures reliable monitoring.  
- **Small Form Factor:** Available in a compact 16-QSOP package.

Application Scenarios & Design Considerations

DAC-Controlled Boost Inverter LCD Bias Supply with Internal Switch

Alternative Part Number

  • LTC1983ES6-5#PBF --: Pin-compatible inverting charge pump regulator with similar input range and output current, widely available and well documented.
  • TPS60403DBVR --: Unregulated inverting charge pump in SOT-23 with comparable voltage range and output current, low cost and easy to source.
  • ICL7660ACBAZA --: Classic inverting charge pump converter with similar function and voltage ratings, mature and broadly stocked alternative.
  • LTC1550LCMS8-4.5#PBF --: Low-noise regulated charge pump in MSOP-8 with similar function and pin-compatible layout, good drop-in candidate for the MAX686 charge-pump regulator.
  • TPS60110PW --: Regulated charge-pump voltage converter with comparable output current and shutdown control, widely available and cost-effective alternative.
  • LM2776TMX/NOPB --: Small regulated charge-pump inverter with low quiescent current, suitable functional replacement when layout can be adjusted.
