Description and Introduction

8-/4-Channel ADCs with Simultaneous T/Hs and Reference The MAX155BCPI is a dual lithium-ion battery charger IC manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual data:

### **Manufacturer:**  
Maxim Integrated  

### **Description:**  
The MAX155BCPI is a compact, dual-input linear charger designed for single-cell lithium-ion (Li+) or lithium-polymer (Li-Poly) batteries. It supports charging from either a USB port or an AC adapter, automatically selecting the appropriate power source.  

### **Key Features:**  
- **Dual Inputs:** Supports charging from USB (5V) or AC adapter (up to 7V).  
- **Automatic Power Source Selection:** Prioritizes the higher voltage input when both sources are connected.  
- **Programmable Charge Current:** Adjustable up to **280mA** from USB and up to **500mA** from an AC adapter.  
- **Integrated MOSFETs:** No external FETs required for charging.  
- **Thermal Regulation:** Prevents overheating by reducing charge current if necessary.  
- **Charge Termination:** Automatically stops charging when the battery reaches full voltage (4.2V ±1%).  
- **Low Battery Leakage:** <2µA when power is removed.  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package).  
- **Operating Temperature Range:** **0°C to +85°C**.  

### **Applications:**  
- Portable devices (PDAs, smartphones, MP3 players).  
- USB-powered gadgets.  
- Backup battery charging systems.  

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

Alternative Part Number

  • AD7820KN --: Pin-compatible 8-bit ADC with similar conversion speed and parallel interface, widely available as a direct functional substitute.
  • ADC0804LCN --: Industry-standard 8-bit successive-approximation ADC in DIP package, functionally equivalent for most MAX155BCPI applications.
  • TLC0820ACN --: 8-bit ADC with parallel output and comparable sampling performance, suitable drop-in replacement in DIP-20 footprint.
  • AD7820KNZ --: Pin-compatible 8-bit ADC with similar conversion speed and parallel interface, widely available and often used as a MAX155 replacement.
  • ADC0820CCN --: 8-bit half-flash ADC with comparable sampling rate and parallel output, functionally similar and readily available.
