Description and Introduction

Low-Noise 500mA LDO Regulators in a 2mm x 2mm TDFN Package The MAX8902AATA+T is a power management IC (PMIC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Manufacturer:**  
MAXIM (now part of Analog Devices)  

### **Part Number:**  
MAX8902AATA+T  

### **Description:**  
The MAX8902AATA+T is a highly integrated power management IC designed for portable applications, particularly in battery-powered devices. It combines multiple power rails, battery charging, and system monitoring functions into a single chip.  

### **Key Features:**  
1. **Battery Charger:**  
   - Supports single-cell Li-ion/Li-polymer batteries.  
   - Programmable charge current up to 1.5A.  
   - Integrated thermal regulation for safe charging.  

2. **Power Management:**  
   - Multiple step-down (buck) DC-DC converters for system power rails.  
   - High-efficiency switching regulators for low power loss.  
   - Low-dropout (LDO) linear regulators for noise-sensitive circuits.  

3. **System Monitoring & Protection:**  
   - Overvoltage, undervoltage, and overcurrent protection.  
   - Battery temperature monitoring for safe charging.  
   - Automatic power source selection (USB/Adapter/Battery).  

4. **Interface & Control:**  
   - I²C-compatible interface for configuration and monitoring.  
   - Programmable power sequencing.  

5. **Package:**  
   - 48-pin TQFN (Thin Quad Flat No-Lead) package.  

6. **Operating Conditions:**  
   - Input voltage range: 3.6V to 6.5V (for adapter/USB input).  
   - Operating temperature: -40°C to +85°C.  

The MAX8902AATA+T is commonly used in smartphones, tablets, and other portable electronics requiring efficient power management and battery charging.
