Description and Introduction

1.4MHz SOT23 Current-Mode Step-Up DC-DC Converter The MAX1896EUT is a linear battery charger IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (MAXIM)  
- **Part Number:** MAX1896EUT  
- **Package:** SOT-23-6  
- **Input Voltage Range:** 4.5V to 12V  
- **Charge Voltage:** 4.2V (adjustable)  
- **Charge Current:** Up to 500mA (programmable)  
- **Charge Termination:** Automatic (based on current threshold)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX1896EUT is a compact, standalone linear charger designed for single-cell lithium-ion (Li+) batteries. It integrates a current-limited pass transistor, thermal regulation, and charge termination circuitry, eliminating the need for external MOSFETs or blocking diodes.  

### **Features:**  
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  
- **Automatic Recharge:** Initiates charging if battery voltage drops below a threshold.  
- **Charge Status Output:** Open-drain output indicates charging or completion.  
- **Low Dropout Voltage:** Allows efficient charging even with lower input voltages.  
- **Reverse Battery Protection:** Safeguards against incorrect battery connections.  
- **No External FET or Diode Required:** Simplifies design and reduces BOM cost.  

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