Description and Introduction

1.4MHz SOT23 Current-Mode Step-Up DC-DC Converter The MAX1896EUT-T is a linear battery charger IC manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 12V  
- **Charge Voltage:** 4.2V (adjustable)  
- **Charge Current:** Up to 500mA (programmable)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT23-6  
- **Charging Termination:** Automatic (based on current threshold)  
- **Preconditioning:** Trickle charge for deeply discharged cells  
- **Reverse Battery Protection:** Yes  

### **Descriptions:**  
The MAX1896EUT-T is a compact, single-cell lithium-ion (Li+) battery charger designed for portable applications. It integrates a power MOSFET, current sensing, and thermal regulation, eliminating the need for external components. The device operates from a DC input and provides a constant-current/constant-voltage (CC/CV) charging profile.  

### **Features:**  
- **Integrated MOSFET:** No external FET required.  
- **Thermal Regulation:** Prevents overheating by reducing charge current.  
- **Charge Status Output:** Open-drain output indicates charging status.  
- **Low Dropout Operation:** Efficient charging even with low input voltage.  
- **Automatic Recharge:** Initiates charging if battery voltage falls below a threshold.  
- **Small Form Factor:** SOT23-6 package for space-constrained designs.  

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