DESCRIPTION
The SMH4042 is a fully integrated hot swap controller that
provides complete power control for add-in cards ranging
in use for basic hot swap systems to high availability
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 at 250V/s.
The SMH4042 continuously monitors the host supplies,
the add-in card supplies and the add-in card current. If the
SMH4042 detects the current is higher than the pro-
grammed value it will shut down the MOSFETs and issue
a fault status back to the host.
The on board E
2
PROM can be used as configuration
memory for the individual card or as general purpose
memory. The proprietary DataDownload mode provides
a more direct interface to the E
2
PROM, simplifying access
by the add-in card
’
s controller or ASIC.
