Part Number:TCAN1043HG-Q1
查询功耗计算公式为:P = [(1-D)*ICCREC*VCC] + [D*ICCDOM*(VCC-VOD)] + [(1-D)*VIO*IIOREC] + (D*VIO*IIODOM) + VSUP*ISUP,按照此公式计算出的功耗为110mW,其中取值为:
- D=50%
- VCC=5V
- ICCREC=5mA
- ICCDOM=70mA
- VOD=2.25V
- VSUP=12V
- ISUP=40uA
- VIO=5V
- IIOREC=5uA
- IIODOM=0.45mA
datasheet中给出的功耗为58mW/126mW,请问能否给出详细的计算方法。
