Description
TMAX≧ΔST1≧TMINか? ただし
TMAXは許容出力電圧範囲に対する上限であり
TMINは許容出力電圧範囲に対する下限である。
ΔSTx nominal deg/s(T)=ΔSTx nominal volt(T)/K(T)、ここで
ΔSTx nominal volt(T)=ΔSTx+a_ΔSTx *[0.0084*(25−T)]+b_ΔSTx *[0.0084*(25−T)]2および
K(T)=Sens+a_Sens*[0.0084*(25−T)]+b_Sens*[0.0084*(25−T)]2
ただし、x=1または2であり、ΔST1、a_ΔST1、b_ΔST1、ΔST2、a_ΔST2、b_ΔST2、Sens、a_Sens、b_Sensは不揮発性ランダム・アクセス・メモリ(NVRAM)内に保存される値である。
TMAX=HW_FILTER_COEFFICIENT_HIGH*ΔSTx nominal deg/s(T)
+上で計算されたしきい値、および
TMIN=HW_FILTER_COEFFICIENT_LOW*ΔSTx nominal deg/s(T)
−上で計算されたしきい値
