Part Number: DRV8432 Hi all,
I am using the DRV8432 with a PWM (21KHz) as a carreir frequency for a ASK procol. I have problems to certificate my device according to CISPR22 (EN 55022) class B radiated limits (30MHz - 1GHz). I am trying to reduce the…
Part Number: DRV8432 Does this driver has any information regarding the mean time to dangerous failure (MTTF_D) or number of cycles until 10% of the components fail dangerously (B_10D)? This inquiry is specifically for the over-current limiting function…
Part Number: DRV8432 hi,
we are designing a TEC Driver with DRV8432, in our datasheet reference design, we found there is a 4.7uH inductor in OUT path.
we hope to know, whether this inductor is must need?? if yes, how can we select the value of this inductor…
Part Number: DRV8432 Hello Team,
Good day. My Customer is working with our DRV8432, the datasheet mentions the current limit has a part to part accuracy of 20%. They are wondering if they use a trimmable resistor to tune the current limit to the desired…
Hi, Sammi,
I haven’t heard back from you, I’m assuming you were able to resolve your issue. If not, just post a reply below or create a new thread if the thread has locked due to time-out.

Hi Team,
Below is a picture of the chip.
As soon as the customer's board is connected to 12V_gvdd, the otw light will be on. After 24_pvdd is powered on, resetab is connected to high level, and the working mode is mode 4. Pass…
Part Number: DRV8432 您好！在drv8432的datasheet中建议，在使用并联模式中，OUT_A~OUT_D在并联之前需要串联电感或者磁珠，我先在的需求是PWM频率期望在20KHz，电机峰值电流在10A左右，如果串联电感的话，尺寸太大了，所以想串联磁珠，那么对串联的磁珠有什么建议吗，30ohm@100MHz的磁珠可以吗？
Part Number: DRV8432 Hi,
Is there a specification in the datasheet that describes the output voltage precision of the FETs while in parallel bridge mode? I'm looking for something that says "At 20V (or some other voltage) out the voltage can be +/-500mV…
Hi Pablo,
The PWM frequency is constant, it is different between boards (depending of firmware)
Duty cycle varies when DRV8432 generates sine wave on the output after filter, otherwise it is 50%.
My observations:
a) in CBC mode short circuit between outputs…
