Part Number: DRV8343-Q1 Other Parts Discussed in Thread: DRV8300 Hi Team
Please tell me about unused pin processing of DRV8343-Q1. It has a circuit configuration in which one of the three half bridges is unused.
The datasheet contains the following information…
Part Number: DRV8343-Q1 Hello, team
Question about tDRIVE time for DRV8343S-Q1 (SPI device).
Description of the data sheet
The IDRIVE bit setting is at Address 0x06 to 0x08.
For example, one IDRIVE bit setting(Address 0x06) is in the "0000b, 0001b,…
Part Number: DRV8343-Q1 Hello, team
I would like to know IDRIVE by temperature.
Could you share the DRV8343 Q1 version of the below Figure 7-8.data?

Could you check if my IVCP is calculated? About MOSFETs MOSFET Qg = 30 nC fPWM = 1000Hz Number of items= 5
From the formula "Trapezoidal 120°Commutation": IVCP = 30 nC × 1000Hz × 5 = 0.15mA…

Could you tell me when to start counting the time set in the OCP_DEG register of DRV8343-Q1?
For example, after being activated with VINHx= 'H' → 'L', does the count start counting when it first exceeds V…
Part Number: DRV8343-Q1 Hello, team
I want to confirm by calculation that Qgs and Qgd will pass within the set time of "OCP_DEG" register after Gate=On, and that overcurrent will not be detected.
I checked the following documents. www.ti.com…
Part Number: DRV8343-Q1 Hello, team
We would like to know the min. value of iDRIVE under V VM =24 V±8 V condition. However, the datasheet shows the current value of the iDRIVE current under the condition of 5.5 ≤ V VM ≤ 60 V.
We think that the…
Part Number: DRV8343-Q1 Customer was designing DRV8343S schematic, and would like to check how to configure CAL pin. Since they use SPI option, can they leave the CAL pin floating, no matter using auto calibration or manual calibration ?
Part Number: DRV8343-Q1 Hello team,
Let me ask several technical questions regarding some register settings.
1. Is it possible to set TDRIVE_MAX = 20 μ s if ① IDRIVE_xx = 0100b = 15 mA?
2. If DIS_GDF = 1b (disabled), what are the risks to DRV8343S? …
Hi Daria,
This behavior of the voltage divider appears correct, as a low enough resistance path on the phase outputs will be characterized as a short and external voltage sensing of that method may not be desirable.
Is using the appropriate current shunt…
