Part Number: DRV8145-Q1 We are using 20kHz PWM with the DRV8145. They need to see how the triangle current waveform would look with the DRV8145 operating at a 20kHz PWM. They want to make sure that they are catching the peaks and not bandwidth limited…

Hey Fabio,
Give us a day to look into this, good question.
Can you share their load profile peak and continuous current, and voltage level? We have some recently released integrated drivers they might be interested in that are very high current (for integrated…
Part Number: DRV8899-Q1 Other Parts Discussed in Thread: DRV8873-Q1 , DRV8876-Q1 , , DRV8245-Q1 , DRV8145-Q1 Hi, TI,
I would like to check with you about the leakage on AOUT1, AOUT2, BOUT1 and BOUT2, when driver outputs are disabled (Hi-Z state)? and i want…
Hi Joaquim,
Thanks for reaching out to us via this forum. Based on the motor specs the peak current could be 30.5 A @ 10 V. This is typical of high torque BDC motors. Peak current occurs at startup inrush and while the motor is stalled. Another area to…
Part Number: DRV8244-Q1 Other Parts Discussed in Thread: DRV8842 , DRV8245-Q1 , DRV8703-Q1 , DRV8145-Q1 Hi Team,
The customer use DRV8244-Q1 to driver door motor, OCP_SEL=0b(customer don't change this register use MCU, the value should be 0b after reset…
Hi Jacob,
I think you may be using the default Slew Rate SR setting which is slow for this high current. You may want to try one of the last three highest values. I noticed the GUI values had typo mismatch with the datasheet but functionally they match…
Hi Kyle,
Kyle Heslop said: Would the move to the DRV8145-Q1 would be better to account for the higher current in this scenario?
Yes, the DRV8145-Q1 would be better suited for a higher maximum current, however the rms current would need to be considered…
Other Parts Discussed in Thread: DRV8144-Q1 , DRV8143-Q1 , DRV8145-Q1 Hi Team,
Could you help recommend a motor which is able to meet the following requirements:
a. Voltage is greater than 16V.
b. Current ≥ 20A.
c. PWM control.
d. With current sensing…
