Description  
The Si3460 is a single-port, –48 V power management controller for  
IEEE 802.3af-compliant Power Sourcing Equipment (PSE). Designed  
to minimize system cost and ease implementation in embedded PSE  
endpoint (switches) or midspan (power injector) applications, the  
Si3460 operates directly from a 12 or 15 V input supply and integrates  
a digital PWM-based dc-dc converter for generating the –48 V PSE  
output supply. The IEEE-required Powered Device (PD) detection  
feature uses a robust 3-point algorithm to avoid false detection events.  
The Si3460's reference design kit also provides full IEEE-compliant  
classification and PD disconnect. Intelligent protection circuitry  
includes input undervoltage lockout (UVLO), classification-based  
current limiting, and output short-circuit protection. The Si3460 is  
designed to operate completely independently of host processor  
control. An LED status signal is provided to indicate the port status,  
including detect, power good, and output fault event information for  
use within the host system. The Si3460 is pin-programmable to  
support endpoint and midspan applications as well as each of the  
different classification power levels specified by the IEEE 802.3af  
standard. A comprehensive reference design kit is available (Si3460-  
EVB), including a complete schematic and BOM (Bill-of-Materials) for  
the dc-dc converter and PSE functions.
