Part Number:DRV110
Hi,
Our plan is to set Ipeak and Ihold of the DRV110 with a SN74CB3Q3253 (Dual 1-of-4 FET Mux/Demux). This device is supplied with a 3.3V supply allowing switching voltage to be up to 5V. Therefore I have the following question:
How can I calculate the voltage at the HOLD and PEAK pins with a given resistor switched to those pins? I want to make shure that the voltage does not rise above the 5V limit of the switch.
A second question is about the calculation of the series resistor for the zener diode. In the datasheet there is equation 5 telling Rs is depending on VsmaxDC. If I look into the calculation spreadsheet for the DRV110 I can see that one parameter is "Vs,min (V)" to choose the resistor Rs. What is correct, datasheet or spreadsheet?
Thnaks and best regards,
Patrick
