Part Number: DRV8843 Tool/software: Hello TI expert team,
I'm using DRV8843 for stepper motor drive. I found out there's a saying in datasheet: "The current through the motor windings is regulated using a fixed-frequency PWM scheme."
In my test result…
Part Number: DRV8843 Hi Expert,
I am using DRV8843 to drive brushed DC motor, but I am a newer to motor driver, I want to use fast decay mode, and need to control turn on/turn off and motor speed, can you help me solve below questions?
1.How to control…
Part Number: DRV8843 Other Parts Discussed in Thread: DRV8842 I'm looking for the OCP time value which is not exist in the datasheet.
In addition, the timing which the H-bridge will be disabled is also not exist in the datasheet.
Pls advice.
Part Number: DRV8843 Other Parts Discussed in Thread: DRV8424 Evidently we know the pinout between the DRV8843 and DRV8424 are not the same, but this customer will build a module to adapt either option on the same PCB. When comparing the simplified schematic…
Part Number: DRV8843 Other Parts Discussed in Thread: DRV8803 , DRV103 , TPL7407LA , ULN2003A Hi,
Customer have been testing the DRV8803 and 8843 as a solenoid valve driver in their application. According to them, these ICs have shown to have inferior…
Part Number: DRV8843 Other Parts Discussed in Thread: DRV8870 Hello
We wish to driver the AIN0/1 of the DRV8843 with a 200KHz 50% duty cycle signal.
The AIN0/1 are complantery (180 degress out of phase with respect to each other).
The same the BIN0…
Part Number: DRV8843 Other Parts Discussed in Thread: DRV8343-Q1 Hi
I would like to ask 2 questions after reading datasheet:
1. Does it support FOC and sinewave algorithm？
2. The chip has built-in 3 sampling resistors, can I sample at the same time…
Part Number: DRV8843 Dear Team,
I want to check if the following a power up configuration is possible:
nRESET – '1'
nSLEEP – '0'
Is this configuration is proper on power up?
Do you see any problem to power up the driver while nRESET signal…
Hi Frederic,
The main difference from these two devices is with the H-Bridge Logic. Other than that you are correct, they are identical.
Please look closely to both bridge control sections in the datasheets to decide which one you want to use.
The…
Part Number: DRV8843 Other Parts Discussed in Thread: DRV8870 Hi all Would you mind if we ask DRV8843? Please refer to the attachment file, and could you give us the advice? 20180718_DRV8843.pdf Kind regards, Hirotaka Matsumoto
