Original question:
Hi all,
In the design, customer set SHUT_12V_B to 12V output high enable and controls DC-DC power-on. SOCPL_SHUT_12V_REQ_3V3 is 12V power-on trigger signal, "high" is enable.
When verifying on the Demo board, when SOCPL_SHUT_12V_REQ_3V3 is high. After 12V enable is turned on, if SOCPL_SHUT_12V_REQ_3V3 is set low again, it is found that the 12V enable signal is always on and cannot be turned off to power off 12V.
