7.14.3

Input PWM 2 Vth for flash mode

The voltages are referred to ground.

6V < VS < 18V; 4.5V < V1 < 5.3V; all outputs open; Tj = -40°C...130°C, unless otherwise

specified.

7.14.4

DI timing

The voltages are referred to ground and currents are assumed positive, when the current

flows into the pin. 6V < VS < 18V; 4.5V < V1 < 5.3V; all outputs open; Tj = -40°C...130°C,

unless otherwise specified.
