The LTC4242 is a dual slot hot swap controller from Linear Technology, specifically designed for PCI Express applications. This controller allows for live insertion into PCI Express backplanes, ensuring system stability during component changes.
Key features include independent control for main and auxiliary supplies, a 20V rating for the 12V supply input, and integrated 0.25 Ohm AUX switches. The device limits fault current in less than 1 microsecond and offers adjustable supply voltage power-up rate. It also includes high-side drivers for N-channel MOSFETs, fault output, and power good output.
The LTC4242 is available in SSOP-36 and QFN-38 packages. It operates within a temperature range of 0°C to 70°C or -40°C to 85°C, depending on the specific variant. The circuit breaker threshold is set at 50mV for 3.3V and 12V supplies, and 550mA for the 3.3V auxiliary supply, with an accuracy of 10% and 6 circuit breakers.
This component is suitable for designs requiring robust power management and protection for PCI Express slots, enabling hot-swapping capabilities without system interruption.
