Description

The SMH4044 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 SMH4044 continuously monitors the host supplies, the add-in card supplies and the add-in card currents. If the SMH4044 detects the current is higher than the programmed value it will shut down the MOSFETs and issue a fault status to the host.

The internal 256 × 8 E2PROM can be used as configuration memory for the individual card or as general purpose memory.

SMH4044 Programming of configuration, control and calibration values by the user can be simplified with the interface adapter and Windows GUI software obtainable from Summit Microelectronics.
