Summit Microelectronics
PRODUCT DESCRIPTION
The SMH4803A is an integrated solution for high reliability systems to monitor and react to events that could have a detrimental effect on a system. It can contain or limit faults to a single circuit board before that fault propagates to the system. Its programmability lets a single board satisfy multiple circuit demands while customized to meet special requirements.
