  • [FAQ] TPS23754: Should APD be tied to Vss for PoE input ORing?

    Part Number: TPS23754 Hi, In our POE PD design we must tie 'APD' to 'Vss' so that DC adaptor input can be in parallel with full-bridge output. Is there any concern? The output of POE PD is fixed to 12V and the input range of adaptor is 18V ~ 48V…

  • [FAQ] How do I terminate any unused channels of a logic device?

    FAQ: Logic and Voltage Translation > Input Parameters >> Current FAQ CMOS Inputs All CMOS inputs must be terminated at either Vcc or Ground. The inputs of a CMOS device are high-impedance. These terminations can be through a resistor (for example…
