Part Number: DRV8847 Hi Sir,
May I know what will happen if ISENS12 & ISENS34 using 150ohm resistor?
A understand, this is current limit resistor, it will limit to 1mA if using 150ohms, is it correct?
Thanks, Ian.
Part Number: DRV8847 Hi team,
This is a failure case of DRV8847S. I compared the impedance of pin to GND of each pin, which is shown in following table.
A crucial phenomenon is that there is a burn mark on the top of package around VM pin. And when I …
Part Number: DRV8847 Hi Team
Does the DRV8847 supports the digital pin control single while the VM left open as below?
The customer is worrying about latch-up might damage the chip during this event.
According to datasheet 6.1 DRV8847 should supports…
Part Number: DRV8847 I am trying out the drv8847pwr as my prototype as nema 17 stepper motor driver. I have tried 2 stepper motor on the breadboard with similar configuration and only swapping out stepper motors. Below is my setup: Stepper motor A: www…
Part Number: DRV8847 Hi team,
My customer is using DRV8847 for 1ch DC motor application, so IN3/4 and OUT3/4 are left OPEN.
When he started evaluation, the nFAULT was driven low and not able to operate.
Could you tell me if it is due to the floated IN…
Part Number: DRV8847 Hi Team,
Our customer will use the DRV8847 to drive a relay. However, she would like to know if she can set OUT1 and OUT2 to logic high to break or deactivate the relay. Table 3 of the datasheet shows the outputs 1-4 at different conditions…
Part Number: DRV8847 Hi,
I will check the VM inrush voltage and current at VM pin when the condition is happening.
Can I ask you first if VM rising when the motor was still running by obstruction stuck for a while?
thanks.

Part Number: DRV8847 Hi, Customer wants to calculate the accuracy when Iout set = 500mA. (Rsense=0.3Ω±1%)
The following formula is described in the data sheet. We consider Risense and Vtrip accuracy for Itrip accuracy calculation. Is this way…
Part Number: DRV8847 I'm having a very strange issue with the DRV8847S on a custom board. I am using 3 of these parts on my board and therefore have to set the addresses for each. When I first write to address 0x60 (the default address), I never get…
