1. IOLD parameters, in the range 8 V to 16 V, are guaranteed by design and characterization. Production testing is done at

13.5 V.

Wake-up inputs (WU1, DIR/WU2)

The voltages are referred to GND and currents are assumed positive, when the current flows into the pin.

6 V ≤ VSREG ≤ 28 V; TJ = from

‑40 °C to 150 °C, unless otherwise specified.
