Description and Introduction

NPN Silicon Transistor The STC918U is a battery charger IC manufactured by AUK. Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 6.5V  
- **Output Voltage:** 4.2V (fixed for single-cell Li-ion/Li-polymer batteries)  
- **Charge Current:** Up to 1A (programmable via external resistor)  
- **Charge Termination:** Constant Current (CC) to Constant Voltage (CV) transition, with auto-cutoff  
- **Standby Current:** Low (typically < 10µA)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOT-23-5  

### **Descriptions:**  
- The STC918U is a linear charger IC designed for single-cell Li-ion/Li-polymer batteries.  
- It integrates over-voltage protection (OVP), thermal regulation, and charge status indication.  
- Suitable for portable devices like Bluetooth headsets, smartwatches, and small electronics.  

### **Features:**  
- **Auto Charge Termination:** Stops charging when the battery reaches full voltage.  
- **Thermal Regulation:** Reduces charge current if temperature exceeds safe limits.  
- **Reverse Leakage Protection:** Prevents battery discharge when input power is removed.  
- **Charge Status Indication:** LED output pins for charging/full status.  
- **Compact Design:** Small SOT-23-5 package for space-constrained applications.
