description (continued)
Fully programmed sequencing control ramps the back-end plane voltages in order, and during shutdown from
a healthy state, turns off the back-end supplies in the reverse order. In addition, electronic circuit breakers
provide continuous protection for the system supplies during the plug-in operation. The control and status pins
can interface directly to the back-plane BD_SEL# and HEALTHY# signals. A precharge pin (PRECHG) provides
a 1-V bias supply for the I/O signals.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages are with respect to GND.
Currents are positive into, and negative out of the specified terminal.
