Description and Introduction

Load Share Controller The UC3907DW is a battery charger controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UC3907DW  
- **Package:** SOIC-16  
- **Function:** Lead-Acid Battery Charger Controller  
- **Operating Voltage Range:** 9V to 40V  
- **Output Current:** Adjustable (external components dependent)  
- **Charging Modes:** Bulk, Float, and Trickle Charge  
- **Temperature Compensation:** Built-in for optimal charging  
- **Control Method:** PWM (Pulse Width Modulation)
