Hi all
Would you mind if we ask DRV110?
<Question1>
We would like to confirm Cin "Input capacitor between VIN and GND".
The recomended value is 1.0uF upto 4.7uF.
The customer would like to configure as follows;
-Ihold : 100mA
-IPeak : 500mA
-Vs : 55V
-> We will confirm each constant(RPEAK, RHOLD and RSENSE).
They could not configure Ihold=100mA, actual value was 200mA.
With increasing VS, Ihold value was increased, is it correct operation?
And then, with out Cin, Ihold was 120mA. Does Ihold depends on Cin?
What is Cin used for? For ripple rejection?
Should Cin be between 1.0uF and 4.7uF?
<Question2>
We would like to know Equation2 and Equation3 correctly.
What is 66.67khom calculated?
We would like to calculate Vref, so could you share us formula for it?
Kind regards,
Hirotaka Matsumoto
