Description and Introduction

High-Speed, 8-Channel, 8-Bit ADC with Simultaneous Track/Holds and Reference The MAX155BCPI+ is a battery charger IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX155BCPI+  
- **Package:** 8-pin PDIP (Plastic Dual Inline Package)  
- **Input Voltage Range:** 4V to 7V (USB-compatible)  
- **Charge Voltage:** 4.2V (adjustable)  
- **Charge Current:** Programmable up to 280mA (USB mode) or 500mA (wall adapter mode)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Charge Termination:** Automatic (based on charge current threshold)  
- **Battery Type:** Single-cell Li-ion or Li-polymer  

### **Descriptions:**  
The MAX155BCPI+ is a compact, linear battery charger IC designed for single-cell Li-ion/Li-polymer batteries. It supports both USB and wall adapter power sources with automatic input selection. The device integrates thermal regulation to prevent overheating and includes charge termination based on current thresholds.  

### **Features:**  
- **Dual-Input Power Source:** Automatically selects between USB and wall adapter inputs.  
- **Programmable Charge Current:** Up to 280mA (USB) or 500mA (wall adapter).  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  
- **Charge Status Output:** Open-drain output indicates charging or completion.  
- **Low-Power Mode:** Minimizes battery drain when input power is removed.  
- **No External MOSFET or Blocking Diode Required:** Simplifies design.  
- **Compact 8-Pin PDIP Package:** Suitable for space-constrained applications.  

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

Application Scenarios & Design Considerations

High-Speed, 8-Channel, 8-Bit ADC with Simultaneous Track/Holds and Reference

Alternative Part Number

  • AD7820KNZ --: 8-bit successive-approximation ADC with similar sampling rate and parallel interface, pin-compatible in many designs and widely available.
  • ADC0804LCN --: Classic 8-bit microprocessor-compatible ADC with comparable resolution and conversion speed, easy drop-in for legacy MAX155 sockets.
  • TLC0820ACN --: 8-bit high-speed ADC with parallel output and similar timing characteristics, suitable functional replacement when exact pinout is not critical.
