DESCRIPTION
This circuit is basically switch mode current
regulator with 2 modes (In-rush and Holding).
In-rush current occurs in the first 64 ms of each

on/off cycle with the rise time dependent on the
coil鈥檚 resistance and inductance. The Hold-current
is a partition of the In-rush current fixed by the
ratio between V

. A control pin is provided
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.
