Part Number: DRV8873S-Q1EVM Hi team,
Here's an issue from the customer may need your help:
The evaluation board's GUI software sets the motor frequency to 20k and cannot be manually set. The customer would like to know is there a software routine…
Part Number: DRV8873S-Q1EVM Hi Team, Our customer would like to inject the charge pump undervoltage fault (CPUV) on the DRV8873S-Q1EVM connected to another EVM with another microcontroller. Would this be possible without damaging the driver for good? If…
Part Number: DRV8873S-Q1EVM Hi.
I saw in your example code (drv8873x-q1.c) for function drv8873xq1_spiInit with the comment below...
/*The errata of the DRV8873S requires enabling the internal mcu pullup */ // set internal pullup for SDO
What is this…
Part Number: DRV8873S-Q1EVM Hi,
We are checking the Short circuit to Supply error in the DRV8873S IC Low Side FET.
By considering the following diagram as a reference, we tested for SCG (Short to GND) & SCP (Short to Supply), but SCP Fault is not…
Part Number: DRV8873S-Q1EVM Dear all,
here is the problem description for the Valve driver (DRV8873S-Q1) from TI:
We need to configure the valve driver to independent half bridge mode:
(IC1 Control Register 0x52).
However, the behaviour of the driver…
Part Number: DRV8873S-Q1EVM Other Parts Discussed in Thread: DRV8873-Q1 , DRV8873 Hi.
I noticed in the evaluation software that SPI transactions are being done as two 8-bit transactions (drv8873x-q1.c, function drv_8873xq1_readRegister). I was expecting…
Part Number: DRV8873S-Q1EVM hi .
i'm using DRV8873S. mode is PH/EN.
when duty of pwm is 50%, open load detection in active mode is good well .
i've checked by reading fault status register & diag status register.
but when duty of pwm is…
Part Number: DRV8873-Q1 Other Parts Discussed in Thread: DRV8873H-Q1EVM Hi
We are planning to use DRV8873HPWPRQ1 in our automotive project. The control i/o's would be interfaced to STM320B! microcontroller.(operated at 3.3V) We want a motor driver with…
Part Number: DRV8873S-Q1EVM Hi team,
we are using DRV8873S-Q1 in our design for 6.5A continious current and 10A peak current.
Please confirm the Sense resistor to be used in the design.
in our design both IPROPI1 and IPROPI2 signals are tied together…
