PD64001 1-port PoE Manager Datasheet
Preliminary
Maximum Ratings ____________
Vmain………………………………………………… -0.3 to 60 V
xRESETN input voltage…………………………. -0.5 to 5 V
Application circuitry DC current ….………………25 mA
ESD (Human Body Model)…………….……..… -2V to 2kV⁽¹⁾
Lead temperature (soldering, 10 s)……………. 300 °C
Notes:.
(1) _{ESD testing is performed in accordance with the Human Body}
Model (CZap = 100 pF, RZap = 1500 Ω).
Stresses beyond those listed above may cause permanent
damage to the device. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
