Part Number: DRV8705S-Q1EVM Tool/software: Hi teams,
Regarding the bridge drive control of DRV8705S, there are two methods: SPI and hard wire; If only SPI control is used, are there any special connection requirements for the four hard wired interfaces…
Part Number: DRV8705S-Q1EVM Tool/software: I am considering purchasing one EVM boards for my application. I need to drive an inductive load (magnetic dipole antenna) using a 5-20Hz current waveform ON:OFF:-ON:OFF delivering a max current of 9.6A that…
Part Number: DRV8705S-Q1EVM Tool/software:
Hello,
The datasheet of the DRV8705S shows that the bit VGS_HS_DS can be modified R/W
However in the GUI of the EVM this bit appears as reserved
Was the writing of this bit blocked by the microcontroller…
Part Number: DRV8705S-Q1EVM Tool/software: I have been looking for Software driver logic(Complex Driver Code) to integrate on Host Microcontroller to start communication with Motor Driver IC and also start reading parameters from IC. Looking forward a…
Part Number: DRV8705S-Q1EVM Hello,
Our questions concerning OFFline diagnostic with the DRV8705S as follows:
1/-For the activation of the Pull-up and Pull-down current sources, should it always be necessary to activate a Pull up and a Pull-down current…
Part Number: DRV8705S-Q1EVM We have some questions about diagnostics in OFF state with the DRV8705S.
In our application, we use the DRV8705S in HS/LS split configuration.
Since the component datasheet does not detail this paragraph and we have found…
Part Number: DRV8705S-Q1EVM Hello,
We would need your technical support on a TI product: The gate driver: DRV8705S-Q1.(SPI)
*The driver is used to manage two external N-Mosfets (High Side: HS & Low Side: LS): (RDSON=3.3 mΩ) in split HS and LS configuration…
Part Number: DRV8705S-Q1EVM Other Parts Discussed in Thread: DRV8705-Q1 , DRV8770 Hello,
I had a hard time with the bootstrap capacitor. The higher the output current is, the bootstrap capacitor will pull a higher current (instant spikes) that causes…
Hey Mahfoudh,
Mahfoudh Bou said: * We launch a cycle with a PWM=100% (Frequency=4Hz) and we apply a short circuit to ground on the signal relied to Pin 21: SH1 of the gate driver.
According to the functional safety document this should result in HS1…
