6) Device on 50mm*50mm*1.5mm epoxy PCB FR4 with 6cm2 (one layer, 70µm thick) copper area for Vbb

connection. PCB is vertical without blown air. See page 14

7) See timing diagram on page 11.

8) Supply voltages higher than Vbb(AZ) require an external current limit for the GND and status pins (a 150Ω

resistor for the GND connection is recommended). See also VON(CL) in table of protection functions and

circuit diagram on page 8.

9) Measured with load; for the whole device; all channels off

10) Add IST, if IST > 0
