Description and Introduction

PCI-Bus Hot Swap Controller The LTC1643ALCGN is a Hot Swap Controller manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Linear Technology (Analog Devices)
- **Part Number:** LTC1643ALCGN
- **Package:** SSOP-16
- **Operating Temperature Range:** 0°C to 70°C
- **Supply Voltage Range:** 2.7V to 15V
- **Quiescent Current:** 500µA (typical)
- **Gate Drive Voltage:** 12V (typical)
- **Fault Detection:** Overcurrent, Undervoltage, and Overtemperature
- **Adjustable Current Limit:** Yes
- **Power Good Output:** Yes
- **Fault Timer:** Adjustable

### **Descriptions:**
The LTC1643ALCGN is a dual Hot Swap controller designed to safely insert and remove boards from live backplanes. It provides inrush current control, fault protection, and power-good monitoring for two independent power supplies (typically 3.3V and 5V). The device ensures smooth power-up by controlling external N-channel MOSFETs and protects against short circuits, overcurrent, and undervoltage conditions.

### **Features:**
- Dual Hot Swap controller for two power supplies (e.g., 3.3V and 5V).
- Adjustable current limit with external sense resistors.
- Programmable fault timer for overcurrent protection.
- Undervoltage lockout (UVLO) protection.
- Power-good output signals for each supply.
- Low quiescent current (500µA typical).
- 12V gate drive for N-channel MOSFETs.
- SSOP-16 package for compact designs.

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