Description and Introduction

High-Efficiency, 40V Step-Up Converters for 2 to 10 White LEDs The MAX1554ETA+T is a battery charger IC manufactured by Maxim Integrated.  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1554ETA+T  
- **Package:** 8-pin TDFN (3mm x 3mm)  
- **Input Voltage Range:** 4V to 7V  
- **Charge Voltage:** 4.2V (adjustable)  
- **Charge Current:** Up to 800mA (programmable)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Charge Termination:** Automatic (based on current threshold)  
- **Protection Features:** Thermal shutdown, reverse discharge protection  
- **Compliance:** RoHS compliant  

### **Descriptions:**  
The MAX1554ETA+T is a compact, linear battery charger designed for single-cell lithium-ion (Li+) or lithium-polymer (Li-Poly) batteries. It integrates a power MOSFET, current sensing, and thermal regulation, eliminating the need for external components.  

### **Features:**  
- **Programmable Charge Current:** Adjustable via an external resistor.  
- **Thermal Regulation:** Prevents overheating by reducing charge current.  
- **Automatic Recharge:** Initiates charging when battery voltage falls below a threshold.  
- **No External FET Required:** Built-in power MOSFET simplifies design.  
- **Low Dropout Operation:** Efficient charging even with low input voltage.  
- **Charge Status Output:** Indicates charging and fault conditions.  

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