Part Number: DRV8332 I'm using DRV8332 for BLDC motor control with a PWM frequency of 200 kHz. A few times (like once a week) the fault pin goes low. I'm running CBC current protection mode so I'm assuming that this indicates a UVP fault. By reading the…
Part Number: DRV8332 We are using a DRV8332 for sinusoidal control of a BLDC motor.
The chip operates correctly for a while and then randomly fails; I measure a short between the GVDD pins and Gnd. I have replaced the chip twice so far, so I would like…
Part Number: DRV8332 Hi,
We are trying to run the DRV8332 on a breadbord but have already burnt 3 of them. We still did not find the issue, but we are worried if it can be in the connection of the three RESET_X ports. We are fixing them at 3.3V expecting…

Hi
I have a BLDC motor with hall effect sensor and I have to design a driver for it.
I want to use DRV8332 IC for drive my BLDC motor but I don't want to use my MCU for commutation step. I…
Part Number: DRV8332-HT Team,
The product folder overview states peak output current = 13A. The datasheet states peak output current = 7A.
Can you clarify that mismatch?
Thanks!
Part Number: DRV8332
Looking at the DRV8332 datasheet the VDD Pin system design requirements talks about both VDD and GVDD. Is there any discussion about requirements of capacitance on GVDD and PVDD?
I see examples in the application circuits but there…
Qiang,
The DRV8312 and DRV8332 offer the same pins and functionality, main difference being that the DRV8332 has a larger top mounted heat slug for easier use of a heatsink.
The programming, trimming, control of both devices are identical.
Are you using…
Part Number: DRV8332 The DDW-44 package drawing is included.
Searching TI's website ( http://www.ti.com/packaging/docs/searchtipackages.tsp?packageName=SO ) shows the DKD-36 package datasheet ( http://www.ti.com/lit/ml/mpds126l/mpds126l.pdf ) is also…
Hey Jimmy,
The maximum operating temperature is 185 C which is lower than the ~200 C you are testing at.
I also assume you are likely doing ~200 C ambient which means our device will heat up over that 200 as well.
This means the device failed outside…
