Operating Conditions
Electrical Characteristics (VCC = 12V, Tamb = 25°C)
Note: 19 These parameters are not tested on each unit. They are measured during our internal qualification procedure
which includes characterization on batches coming from corners of our process and also temperature
characterization.
Note: 20 To make soft start possible, 0.5mA are sunk when B+ is disabled.
Note: 21 The external power transistor is OFF during 400ns of the HFOCUSCAP discharge
