Description and Introduction

+5V, Low-Power, 12-Bit Serial ADCs The MAX189CEWE is a battery charger controller IC manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX189CEWE  
- **Package:** 16-pin Wide SOIC (SOIC-16)  
- **Input Voltage Range:** 4.5V to 28V  
- **Charge Voltage Accuracy:** ±0.75%  
- **Maximum Charge Current:** Programmable up to 4A  
- **Charge Termination:** Programmable timer or voltage-based  
- **Operating Temperature Range:** 0°C to +70°C  
- **Control Method:** Linear regulation  

### **Descriptions:**
- The MAX189CEWE is a high-performance lithium-ion (Li+) battery charger controller.  
- It provides a complete charging solution for single-cell or multi-cell Li+ batteries.  
- The device includes thermal regulation to prevent overheating during charging.  
- It supports both constant-current (CC) and constant-voltage (CV) charging modes.  

### **Features:**
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds a safe threshold.  
- **Charge Status Outputs:** Provides signals for charge in progress (CHG) and charge complete (POK).  
- **Low Dropout Voltage:** Enables efficient charging even with lower input voltages.  
- **Reverse Battery Protection:** Safeguards against incorrect battery connections.  
- **Automatic Recharge:** Initiates charging if battery voltage falls below a threshold.  

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