### **Descriptions:**
The LTC4267IDHC is a high-voltage Hot Swap controller designed to safely insert and remove boards from live backplanes. It provides inrush current control, fault protection, and power monitoring for high-voltage applications. The device features adjustable current limit, undervoltage lockout (UVLO), and overvoltage protection to safeguard sensitive components.

### **Features:**
- **Wide Input Voltage Range:** 9V to 80V operation.
- **Adjustable Current Limit:** Allows precise control over inrush current.
- **Fast Overcurrent Protection:** Prevents damage during fault conditions.
- **Programmable Fault Timer:** Adjustable response time for overcurrent events.
- **Power Good Indicator:** Monitors output voltage status.
- **Undervoltage Lockout (UVLO):** Adjustable threshold for input voltage monitoring.
- **Overvoltage Protection (OVP):** Prevents damage from excessive input voltage.
- **Low Quiescent Current:** 1.5mA typical for power efficiency.
- **Compact DFN-16 Package:** Space-saving design for high-density applications.

This information is strictly based on the manufacturer's datasheet and technical documentation.
