Part Number: DRV8434A-Q1 Tool/software: Hello, experts. I'm using the DRV8434A-Q1 for automotive headlight adjustment.
During testing, when I lowered the voltage from 13.5V to 9V, I noticed that the motor occasionally stalled or rotated erratically…
Part Number: DRV8434A Tool/software: The jitter during power-on is acceptable. In the case of constant power, we want to do every time the motor stops, the next start time do not shake. In addition, after the motor stops, how to maintain the stopped state…
Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434 , , DRV8434S Tool/software: I have 2 questions about utilizing the DRV8434 driver IC to control a stepper motor, the questions are as follows:
1. Using DRV8434 to drive a stepper motor,…
Part Number: DRV8434A-Q1 Other Parts Discussed in Thread: DRV8434 Tool/software: I have two questions for the experts. 1. Can the TRQ_CNT/STL_TH PIN of the DRV8434 be connected to the GPIO of the MCU without the need to connect to the GPIO of the MCU…
Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434S Hi team,
My customer has several questions when using DRV8434A.
1. One of the parameters used in calculating full-scale current is TRQ_DAC. I didn't find a definition in the datasheet…
Part Number: DRV8434A Hi Team,
Issue: the motor does not spin.
Power supply is 15.8 V which is good. Sleep and Enable is high. Fault, TRQ and STL_REP is low. M0 and M1 is high,
For the CPL and CPH pins, the normal board has a pulse waveform, while…
Part Number: DRV8434A Hi Team,
1) M0 and M1 have Hi-Z inputs. Can this Pin float be interpreted as representing Hi-Z state? How to set up GPIOs if using monotholic GPIOs for control? Just with an open-drain output?
2) Other motor drive ICs have 1…
Part Number: DRV8434A Other Parts Discussed in Thread: DRV8434 Hi
We made a version in September and found it OK, and then we made another version in October, with the same schematic diagram and the PCB of the motor It is the same, found that the motor…
Part Number: DRV8434A Hi experts,
1. Without VCC and VM is not connected to the power supply, what will it happen if the voltages apply to the output pins(AOUT pins and BOUT pins)? For example, the user mistakenly turns the motor and applies Back-EMF…
Part Number: DRV8434A Dear Specialists,
