Description and Introduction

Dual-Input Linear Chargers, Smart Power Selector with Advanced Battery Temperature Monitoring The MAX8934EETI+ is a power management IC (PMIC) manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX8934EETI+  
- **Package:** 28-pin TQFN (6mm x 6mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range (VIN):** 2.7V to 5.5V  
- **Output Voltage (Buck Converter):** Adjustable (0.6V to VIN)  
- **Output Current (Buck Converter):** Up to 1.5A  
- **Switching Frequency:** 2MHz (fixed)  
- **LDO Output Voltage:** Adjustable (1.25V to 3.3V)  
- **LDO Output Current:** Up to 300mA  
- **Efficiency:** Up to 95% (Buck Converter)  
- **Quiescent Current:** 30µA (typical)  

### **Descriptions:**
The MAX8934EETI+ is a highly integrated power management IC designed for portable and battery-powered applications. It combines a high-efficiency, synchronous step-down DC-DC converter with a low-dropout linear regulator (LDO). The device is optimized for low-power operation, making it suitable for smartphones, tablets, and other portable electronics.

### **Features:**
- **High-Efficiency Buck Converter:** Up to 95% efficiency with 1.5A output capability.  
- **Adjustable Output Voltages:** Both the buck converter and LDO support adjustable output voltages.  
- **Low Quiescent Current:** 30µA typical for power-sensitive applications.  
- **2MHz Fixed Switching Frequency:** Reduces external component size and improves transient response.  
- **Integrated LDO:** Provides a stable 300mA output for auxiliary power needs.  
- **Power-Good (PG) Output:** Monitors the buck converter output voltage.  
- **Soft-Start and Short-Circuit Protection:** Enhances system reliability.  
- **Thermal Shutdown:** Protects the IC from overheating.
