Part Number: DRV8847 Tool/software: Hi TI,
We use DRV8847 to design a motor driver control board. However, it`s always burned under below work situation:
Motor load: 20Ω. Vout=12V. Ipeak=150mA. Motor speed: 2-3Hz.
Failure ratio: 100%
Test number…
Part Number: DRV8847 Tool/software: Hi team,
Can we provide safety operating area (SOA) of DRV8847's internal FET?
It is mentioned in datasheet 7.3.8.1.3, but my customer requests me to show the entire SOA data if possible.
Best regards,
Kazuki…
Part Number: DRV8847 Other Parts Discussed in Thread: DRV8718-Q1 , DRV8714-Q1 Tool/software: Hi,
This is my design as shown below. The aim is to have 16 independent latching solenoid drivers, but for some reason, it was not able to output a high voltage…
Part Number: DRV8847 Tool/software: Hi expert,
I saw Vil is different when Vcm > or <=7V. Would it be also different for Vih?
Customer may provide 5Vvm for DRV8847, so would like to know what would be Vih threshold.

Allan
Part Number: DRV8847 Tool/software: Using DRV8847 to drive a dc motor,when power on,the nfault pin is high about 10 seconds then change to low level. The motor can run normarly. So I can't justify the motor condition.
Please tell me how to check it
Part Number: DRV8847 Tool/software: Using your DRV8847 dual H-bridge motor driver. Need to know if the VM pin (pin 12) is internally protected against ESD.
V(ESD) is listed at +/-4000V per ANSI/ESDA/JEDEC JS-001

Part Number: DRV8847 Tool/software: Hi expert,
Would you please advise how to reduce undershoot & overshoot at turn on & off ?
p.s.
1. motor supply is 5V
2. C18 has changed from MLCC 10uF/6.3V to 100uF/6.3V

Hi Team,
The above table is the configuration of 8847.
Mode selection is done using the I2C registers in the DRV8847S device variant (see the Programming section). Thus, I have some question:
1. How should IN1 to IN4 of…
Part Number: DRV8847 Hi Team,
Does the parallel mode in the data sheet mean that OUT1 and OUT4 can be connected together, and OUT2 and OUT3 can be connected together to drive a motor, thereby increasing the total output current?
