Part Number: DRV8814 Dear Sir,
The design refers to the old version of the datasheet, the circuit has not added the following resistance(1MΩ), may I ask what will happen?
Thanks, Ian.
Part Number: DRV8814 The datasheet mentions this in order to clear the overcurrent error:
7.4.6.1 Overcurrent Protection (OCP) An analog current limit circuit on each FET limits the current through the FET by removing the gate drive. If this analog current…
Part Number: DRV8814 Dear TI Experts,
We designed a gaming console add-on device based on DRV8814. Below is the schematic of our design. Would you please give us comments if you see any issue regarding to the design? The primary issue that we are experiencing…
Part Number: DRV8814 Dear Expert, Thank you for your special support everyday. I have a simple question about DRV8814. My customer is using DRV 8814. Is it possible to use 10 V chip capacitor for V 3 P 3 OUT (15 pin)? (Customers are using 0.47 μF, 6.3 V, 1005…
Part Number: DRV8814 In the test, it is found that nFault will protect the DC motor when it starts, which causes the motor to not rotate properly, and the phenomenon repeats when it is re-energized.
Testing power supply V_MT, no abnormalities (higher…
Part Number: DRV8814 Other Parts Discussed in Thread: DRV8824 Hello All,
From rev D onwards of the DRV8814 datasheet, it appears in the application diagram a 1Mohm resistor to be placed in parallel with the 100nF bootstrap capacitor for the high MOS drive…
Part Number: DRV8814 Hi all Would you mind if we ask DRV8814? How much is Maximum rating of A/B-OUT1/2? Is the value is Minmum –0.7 to MAX VM + 0.7? As the background of this question, Bout1 might be more than ABS condition.(Please refer to the wave form.…
Part Number: DRV8814 Hi all Would you mind if we ask DRV8814? Our customer would like to DRV8814 for BDC at only A side Motor. So, they don't use B side Motor. Therefore we would like to confirm the termination of unused pins for B side. We assume foll…
Part Number: DRV8814 Hi,
I could not determine what value of bulk capacitors should I use.
I am going to use the Mabuchi RS-385PH-10280 motor.

Part Number: DRV8814 Hi,
I have to measure the current flowing thru a brushed Dc motor in order to find if the motor is loaded too much.
Can I assume that all the current of the motor is flowing thru the sense resistor? (I will, of course, set a very low…
