The current sink to ground ensures that the channels switch off in case of open input pin. The zener diode protects
the input circuit against ESD pulses. After power-on reset, the device enters idle mode (all channel OFF).
5.2.1
When switching off inductive loads, the potential at pin OUT rises to V
intends to continue driving the current. The voltage clamping is necessary to prevent destruction of the device,
