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.

Description and Introduction

8-/4-Channel ADCs with Simultaneous T/Hs and Reference The MAX155BCPI is a dual, step-down DC-DC converter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
MAXIM (Maxim Integrated)  

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Range:** Adjustable from 1.25V to 5.5V (per channel)  
- **Output Current:** Up to 1A per channel (2A total)  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin PDIP (Plastic Dual In-line Package)  

### **Descriptions:**  
- The MAX155BCPI is a dual, step-down (buck) switching regulator designed for high-efficiency power conversion.  
- It integrates two independent PWM controllers with synchronous rectification, reducing external component count.  
- Suitable for distributed power systems, industrial applications, and battery-powered devices.  

### **Features:**  
- Dual, independently controlled outputs  
- Synchronous rectification for improved efficiency  
- Adjustable soft-start for controlled startup  
- Overcurrent and thermal protection  
- Low-dropout (LDO) mode for improved light-load efficiency  
- External synchronization capability
