- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The LTC4070EMS8E#PBF is a low-power, high-voltage battery charger designed for Lithium-Ion/Polymer batteries. It features a low quiescent current, making it suitable for energy harvesting and long-life battery applications. The IC includes an integrated shunt battery charger with a precision float voltage control and thermal regulation to prevent overheating.  

### **Features:**  
- **Wide Input Voltage Range (2.7V to 50V):** Supports high-voltage inputs.  
- **Ultra-Low Quiescent Current:** 1.2µA in standby mode.  
- **Precision Float Voltage Control:** Ensures accurate battery charging.  
- **Thermal Regulation:** Protects the device from overheating.  
- **No MOSFET or Blocking Diode Required:** Simplifies design.  
- **Automatic Recharge:** Initiates charging when battery voltage falls below a threshold.  
- **Small MSOP-8 Package:** Space-efficient for compact designs.  

This IC is ideal for applications like backup power systems, energy harvesting, and portable devices requiring long battery life.
