Part Number: DRV8873S-Q1EVM Tool/software: Hi TI engineer,
The DRV8873S-Q1EVM is used to drive the motor, and the current is measured by an external ammeter. When we prepared 2 configurations of controller →DRV8873S-Q1EVM and measured the current of the…
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 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 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 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…
