The MAX5915/MAX5915A/MAX5916/MAX5916A dual PCI 2.2 hot-swap controllers can safely insert and relocate two PCI cards into a live PCI slot or backplane with limited inrush current at startup. After start-up, these devices provide protection against short-circuit, over-current and under-voltage conditions. The MAX5915/MAX5915A/MAX5916/MAX5916A provide independent power supply control for 3.3 V, +5 V, ±12V, two PCI cards and a +3.3 V auxiliary power supply. These devices provide intelligent selective thermal shutdown control over current to shut down channel faults. All devices include internal power MOSFET +12V, -12V, +3.3V auxiliary output. These devices use an internal charge pump activated gated internal FET to control the +3.3 V auxiliary supply. Internal FET and current sense circuit specification ±12V and +3.3 V auxiliary. Channels A and B operate independently, allowing a single device to monitor two PCI card slots. The MAX5915/MAX5915A provide latching fault protection The MAX5916/MAX5916A provide automatic restart fault protection. The device is available in a low profile 28-pin TSSOP package and is specified over the -40°C to +85°C extended temperature range.
