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 either…
Part Number: DRV8705S-Q1EVM The power supply for DRV8705 is as below:
1. The voltage at DVDD has been checked and it is at ~4.8V. The min. operating voltage of DRV8705 is 3V. => OK
2. The SPI communication with MCU has been checked.
2.1 The high voltage…
Part Number: DRV8705S-Q1EVM Other Parts Discussed in Thread: DRV8705-Q1 , DRV8714-Q1 Hi team,
The customer use DRV8705S-Q1EVM to evaluate DRV8705 and they have an issue. They take all 0ohm resistor off except for the R65 and use their MCU to control the…
Part Number: DRV8705H-Q1EVM Hi Sir,
For our single phase inverter design we want to use DRV8705 gate driver IC with NPH2R608 NH (NMOSFET). Qg = 27nC.
According to our calculations it seems that we may be able to meet the requirements. I did the calculations…
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…
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 MOSFET…
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 yet…
Part Number: DRV8705S-Q1EVM Hi~
In DRV8705 EVM, especially Page #1 H-Bridge part, what is NT1~NT5? What is the purpose of NT1~NT5 and stand for? When I check EVM layout, there is no special things, also couldn't find BOM excel.
Thanks.
