SMH4042A Description
The SMH4042A is a fully integrated hot swap controller that provides plete power control for add-in cards ranging in use for basic hot swap systems to high availability pactPCI systems. It detects proper insertion of the card and senses valid supply voltage levels at the backplane. Utilizing external low on-resistance N-channel MOSFETs, card power is ramped by two high-side driver outputs that are slew-rate limited...
