Part Number: DRV8432 Other Parts Discussed in Thread: DRV8412 , , LM5106 , LM5109 , DRV8705-Q1 Hello,
I'm upgrading a hand-made TEC driver and want to get some features/minituarization from purpose-built ICs.
We're looking at 15V-24V and 6-10A. 24V…
Part Number: DRV8432 Other Parts Discussed in Thread: DRV8711 , DRV8434 Hi,
I am using DRV8432DKD.
In datasheet the mode select pin connection is given in section 9.4.4 as " It is not recommended to connect mode pins to board ground if 1-Ω resistor…
Hi Jacob,
Jacob Wyrick said: Is there any reason we wouldn't or shouldn't add an external charge pump circuit and provide its output to BST_x to achieve 100% duty cycle?
This is not recommended. The external circuit may cause problems with the…
Part Number: DRV8432 hi Team,
we are using your DRV8432 for our design, it's for TEC drive, disign is below, now we found the TEC output was lower than PVDD, for example,
PVDD=15V,but the output is 13.2V, 88% efficiency, as mentioned in datasheet,…
