Hello
My customer intend to choose motor driver for their new design of proportional solenoid driver.
They will select part within 1-1.5month.
Their current solution is analog ( opamp(PID amp) + MOSFET + currnet shunt monitor .)
Major spec is
: 24V+/-10% / 0.5A max
; Load is 15mH ..............should be large
; customer want set current from 0 to 500mA using PWM duty
: Forward/revese should changed
; current and direction should be changed same time in every 1ms.
; Hope to have dithering
; constant current control (= position)
; 2- proportional solenoid valve ( H bridge x 2)
Question
Q1) I had introduced MAX22217 them , but this product has no PWM input.
It seems to change current in every 1ms may be difficult though higher SPI frequency.
How do you think?
Q2)
I intend to promote MAX22201/2/7 , or MAX22205.
I can have MAX22205 LTspice model , but I hope to have MAX22201/2/7 simulation model
in oreder to check I can change current withinf every 1-2ms or not.
Can I have LTspice model for MAX22201/2/7?
Q3)
MAX22205 LTspice model can be used in place of MAX22201/2/7?
Hope to have your advice
Best Regards
