Hi Amaresh,
Thank you for your patience.
While it would be possible to forgo the bootstrap capacitor if you are using a P-FET on the high side of the gate driver, it is not recommended as the device was designed with the intention of being used with 2…
Other Parts Discussed in Thread: MOTOR-DRIVE-FET-LOSS-CALC Hello Ti,
I found this MOTOR-DRIVE-FET-LOSS-CALC tool from Ti web site which is very useful.
for a low side MOSFET switching loss only considered for the electrical frequency of the motor and neglected…
Part Number: LM51231-Q1 Tool/software: Hello,
I am trying to calculate losses for the synchronous MOSFET. In table 2-2, the body diode conduction loss uses a term of (Vload*Fsw)/2. This results in a very high calculated loss. I think the voltage should…
Part Number: CSD88599Q5DC Other Parts Discussed in Thread: CSD88584Q5DC I discovered this spreadsheet recently and am trying to use it. I'm interested in the CSD88599 but it doesn't seem to give that as an option when I select FET Config, it only gives…
Part Number: DRV8316C-Q1 Tool/software: Hi,
I want to estimate losses while using the BLDC driver mentioned.I found this excel sheet for calculation.Do we have an application note to understand the equations provided in this excel sheet

Part Number: LP8866-Q1 Hello,
Could you please provide a brief guideline of how to select the boost FET? What critaria will be applicable to the boost FET for "VGD/(RDS_ON + total resistance to gate input of SW FET) must not be higher than 2.5 A"?…
Part Number: LM5143DESIGN-CALC Other Parts Discussed in Thread: LM5143-Q1 , LM5145 Hi team,
here is two confusing items of LM5143q design:
1.there is a descripton as following in the datasheet what seems not to make sense, actually it suppose that there…
Part Number: LM5140ADESIGN-CALC Other Parts Discussed in Thread: LM5143-Q1 , LM5140-Q1 Hi Experts,
the LM5140ADESIGN-CALC seem to always recommend the same FET. Even when Vin is exceeding the max voltage of the IPC50N04. Is there an issue or is this part…
Part Number: LM5176-Q1 Hi,
I have a question about loss calculation as follows.
When in buck mode, Why is QL1 calculated only as conduction loss? (Is QL1 calculated as conduction by replacing diode in buck mode?) Shouldn't switching loss be considered?…
