Other Parts Discussed in Thread: LMR14050, , TCAN1043
Dear TI's:
i want to use tcan1043-q1 INH pin to wakeup the system power. INH pin connect to lmr14050 EN pin with a resistor and diode.
schemtic as follow.
In Normal operation, TCAN1043Q1 in sleep mode, INH =Hi-Z, LMR14050 Disabled. when wake up, TCAN1043Q1 go to normal state, INH=ON,and
Output high level, then LMR14050 enabled.
But, when Vsup=12V, Vcc and Vio have no power, does tcan1043q1 go to standby mode or sleep mode? and what's the state of the INH pin. thanks.
waveform.
I see the INH pin output H Level when power on,the time about 200ms.so lmr14050q1 start to work. i don’t want it work when power on, can add other cuircuit make the function.
waiting for your advise. thanks very much.
