While 24V is technically above the minimum internal "charge state" threshold, the device is designed specifically for AC to DC rectification and relies on voltage zero-crossings to operate its internal logic and supply charging.</P> <P>BRs, Tomas</P> Mon, 30 Mar 2026 10:47:14 GMT TomasVaverka 2026-03-30T10:47:14Z https://community.nxp.com/t5/Power-Management/DC-Input-with-TEA2209T/m-p/2342100#M5105 <P>Hello. How does the&nbsp;TEA2209T behave with a 24V DC input? Will the GATEHL and GATELR pins be driven HIGH?&nbsp;&nbsp;</P> Mon, 30 Mar 2026 09:34:57 GMT https://community.nxp.com/t5/Power-Management/DC-Input-with-TEA2209T/m-p/2342100#M5105 ElektroCat 2026-03-30T09:34:57Z https://community.nxp.com/t5/Power-Management/DC-Input-with-TEA2209T/m-p/2342146#M5106 <P>Hello Sankalp,</P> <P>The TEA2209T will likely not drive the GATEHL and GATELR pins HIGH with a constant 24V DC input.
