(Note 25) The temperature characteristics are obtained from the following formula.
∆BDET/∆Topr=(((BDETH-BDETL)/BDETM)/115) 10
Detecting / release voltage value at BDETH: 85°C
Detecting / release voltage value at BDETL: -30°C
Detecting / release voltage value at BDETM: 25°C
(Note 26) This is the standard value for the dead time setting capacitor at CBDLY=6800pF, V
