(2)In the case of (1) (voltage…
Part Number: DRV8244-Q1 Hi,
I am having trouble with simulating the DRV8244-Q1 H variant.
I have made a simple schematic that you can see below. The problem is that there is almost nothing on the output.
The NFAULT pin goes HIGH after sending the correct…
Part Number: DRV8244-Q1 Hello Team,
for EMI measurements our customer wants to know the frequency of the charge pump. It's not specified in our datasheet but would be helpful
Many Thanks
Josef
Part Number: DRV8244-Q1 I am deciding on if I am going to use the DRV8244 full H-Bridge chip on a new 4 wheel drive rover product. I wanted to know if it is possible to utilize regenerative breaking to help recharge the battery when the rover is slowing…
Part Number: DRV8244-Q1 Hi team,
Here's an issue from the customer may need your help:
Device number: DRV8244SQRYJRQ1
After initial power-up, the customer tried the operation mentioned in the wake-up function in the manual and gave a pulse waveform…
Part Number: DRV8245-Q1 Other Parts Discussed in Thread: DRV8244-Q1 , Hi Team
We know that DRV8244-Q1's maximum withstand continuous current is 20A. Is it have ability to withstand 25A peak current for 20ms when motor start working?
Part Number: DRV8244-Q1 Hello team,
Could you let me know the difference between "communication enabled" in INIT2 and "Communication available" in STANDBY/ACTIVE?
In the electric char table, "tcom" specification explains "time to…
Part Number: DRV8244-Q1 Hello Team,

1. DRV8244HQRYJRQ1 is HW variant, w e adopt PH/EN mode, and the chip settings are as follows,
Hardware: (1)connecting pin14(SR) and PIN16(MODE…
Part Number: DRV8244-Q1 Hi,
For DRV8244-Q1 SPI(S), if they don’t tie IN1/IN2 pin and only use SPI to control motor speed, should customer just flip “S_EN_IN1” and “S_PH_IN2” bit and simulate it as IN1/IN2 pin, and control the speed just by the flip frequency…
