The SY23213A is an IEEE 802.3 af/at PoE-compliant Powered Device (PD) controller. It features detection and classification modes and a 100V-rated pass switch. Built-in thermal protection accommodates transient and overload conditions by shutting down the pass switch to protect the input source. Inrush current limiting is included to gradually charge the downstream input capacitor without interruption due to die heating.
The SY23213A can automatically generate a pulsed voltage to maintain the PSE power when the downstream DC/DC converter operates in light or noload mode. The AMPS current amplitude is programmable through an external resistor.
