Note 2. Range over which the device is functional.
(Unless otherwise specified, these specifications apply over the operating ambient temperature range of 0°C
For the LX5241/5243 DISCONNECT = L, for the LX5242 DISCONNECT = 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.
