Note 2. Range over which the device is functional.
(Unless otherwise specified, these specifications apply over the operating ambient temperature range of 0°C ≤ T
DISCONNECT: LX5245/47 = L, LX5246 = H. Low duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to
the ambient temperature.)
Note 3. Open circuit failsafe voltage.
