Part Number: DRV8332-HT Can I connect PVDD to 50V and leave GVDD and VDD not connected to 12V?
What will happen? Will this have some effects for the reliability of the chip?
Hi Ryan,
DRV8332-HT die is different from the commercial version. Thus DRV8332-HT does not have OT warning or shutdown. As DRV8332-HT electrical table it does not highlight any OTW ( Over temp warning or shutdown) as is the case with the commercial…
Other Parts Discussed in Thread: DRV8332-HT Hi!
The datasheet for the DRV8332-HT says "
it is recommended to add 26- Ω resistor between the GVDD power supply and GVDD_X pins to limit the inrush current on the internal bootstrap diodes."

Other Parts Discussed in Thread: DRV8332-HT Hi at all,
I develope a HT BLDC servo control with the DRV8332-HT chip. It works fine but with my scope I can see some voltage ripples on each output pin.
The bldc motor has a terminal inductance phase to phase…
Hi Henry,
To give a preliminary answer for now - you may want to look into DRV8332-HT, oriented towards ~175C temperature spec
it still has over-temperature shutdown, but may be triggering at such a level that might be okay for your environment?

Other Parts Discussed in Thread: DRV8332-HT , DRV8332 Hello,
I am looking DRV8332-HT datasheet and I don't understand thermal shutdown part :
Overtemperature Protection The DRV8332 has a two-level temperature-protection system that asserts an active-low…

Hi Dennis,
I should have asked earlier, but thank you for pointing to the datasheet version. SLES274B is the DRV8332-HT (High Temperature) while my questions are for the DRV8332 (Industrial with datasheet SLES256E). The devices are similar but have…
Hi Sanmesh,
Thanks for the information. We will test with the 33nF caps and see how it performs. Measuring BST_A to OUT_A it looks like it stays above +10V at max PWM:
BST_A (yellow), OUT_A (blue), BST_A - OUT_A (red), OUT_A current (green)
As for the…
Hi Roshan tej.,
1) It is fine to connect the RESET_x pins to the GPIOs. Connecting to the GPIO provides more options.
2) The DRV8332-HT recommended maximum peak current is 7 A.
