on/off cycle with the rise time dependent on the
coil’s resistance and inductance. The Hold-current
is a partition of the In-rush current fixed by the
ratio between V
for enabling and disabling the gate control output
for the external power MOS. The MOS transistor
must be chosen according to the supply voltage
range and the current flowing through the
solenoid.
