Oscillator

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

flows into the pin. 4.5 V

 V

S  28 V; all outputs open; Tamb = -40 °C...125 °C, unless

otherwise specified.

8.3

Power-on reset (VSREG)

All outputs open; Tamb = -40 °C...125 °C, unless otherwise specified (see Figure 3).

8.4

Voltage regulator VCC

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

flows into the pin. 6 V

 V

SREG  28 V; Tamb = -40 °C...125 °C, unless otherwise specified.
