Other Parts Discussed in Thread: TCAN1043
Hi team
My customer asks for confirmation of the resistance value connected to the WAKE PIN of TCAN1043.
The using formula calculated is shown below.
VSUP = 26.5V.
R_serise = Vsup/Io(wake) = 26.5V/3mA =8.4kohm.
R_serise tries to apply 10 kohm.(More than 8.4 kohm)
R_bias < ((VSUP – Vih)/Iih) – R_series = ((26.5 – (26.5-1.9V))/Iih) – Rseries = 1.9V/25uA – 10KΩ = 76KΩ
R_bias tries to apply 10 kohm.(Less than 76 kohm)
Question : Is it OK to apply both R_serise and R_bias at 10KOHM?
