Description and Introduction

3.6A, 1.4MHz, Low-Voltage, Internal-Switch Step-Down Regulator with Dynamic Output Voltage Control The **MAX1536ETI+T** is a **battery-charger controller** manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data from the manufacturer:

### **Specifications:**
- **Package:** 28-TQFN (5x5mm)  
- **Input Voltage Range:** 4.5V to 28V  
- **Battery Voltage Range:** 1 to 4.2V (adjustable)  
- **Charge Current:** Up to 4A (programmable)  
- **Charging Accuracy:** ±0.5%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Switching Frequency:** 300kHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Protection Features:** Overvoltage, overcurrent, and thermal shutdown  

### **Descriptions:**
The MAX1536ETI+T is a **high-efficiency, switch-mode battery charger controller** designed for **single-cell Li-ion/Li-polymer batteries**. It supports **constant-current (CC) and constant-voltage (CV)** charging modes with high accuracy. It integrates a **PWM controller** for synchronous rectification, reducing power dissipation.

### **Features:**
- **Programmable Charge Current and Voltage**  
- **Automatic Power Source Selection** (AC adapter or USB)  
- **Dynamic Power Management (DPM)** to prevent input overload  
- **Thermal Regulation** to optimize charging rate  
- **Charge Status Outputs** (LED or microcontroller interface)  
- **Low-Dropout Linear Regulator (LDO)** for system power  
- **Reverse-Battery Protection**  

This device is commonly used in **portable electronics, tablets, and handheld devices** requiring efficient battery charging.
