General Description The SMH4802EVAL kit is a fully functional printed circuit board designed to demonstrate all the features of the SMH4802 Nonvolatile Hot-Swap (live-insertion) Controller. The circuit operates over the full Telecom supply range of -32 to -72VDC, soft-starting loads of up to 4 amperes. The SMH4802EVAL also manages the power-on delay of an external isolated DC-DC converter in addition to many other useful Hot-Swap functions and remote power on/off through the I2C 2-wire bus interface.

 

Several key, user-configurable functions are:
1. User-Configurable under-voltage, over-voltage and over-current limits. 2. 'Power Good' output with programmable delay time to assertion. 3. Power on/off I2C command 4. Programmable over-current filter response time to prevent nuisance tripping. 5. User -Configurable 'Forced Shutdown' pin allows secondary-side fault detection and orderly shutdown.
