Part Number: DRV8834 Hi all Would you mind if we ask DRV8834? The datasheet shows typical Vtrip accuracy only. So, how much are the maximum value and the minimum value? It depends on Xvref, however we assume that it depends on current condition and gain amp toleranace…
Part Number: DRV8834 Please help me with the DRV8834EVM RevB evaluation board.
GUI configuration: dual H-bridge.
Set-up: step motor (3.3VDC rated voltage, 2 phases, max. starting frequency of 800 PPS) connected to AOUT1&AOUT2, BOUT1&BOUT2.
Issue…
Part Number: DRV8834 I am using this driver (DRV8834) to run a stepper in indexer mode. I am trying to minimize the number of control pins I have to connect back to my micro.
Is it required to control both the Enable and Sleep pins? Can I just pull the…
Part Number: DRV8834 Hello Team,
I am facing the following issue with DRV8834
We are driving a stepper motor with it,
The inputs are :
Indexer Mode with M0, M1 = 0
STEP pulses: 15 PWM pulses, 208Hz frequency,
VM = 3.7 ~ 4.2V
Enable pins driven low during…
Part Number: DRV8834 Other Parts Discussed in Thread: DRV8889-Q1 Hello,
I am going to use Motor Driver IC DRV8834 for my new Product.
This product is used in Automotive Environment.
So My Question is: Can I use DRV8834 in Automotive Application?
If No…
Part Number: DRV8834 Hi Team,
2 quick questions regarding the Hi-Z state of the DRV8834
1. What leakage current from the device controlling the mode pins is acceptable to securely set the motor driver to Hi-Z mode?
2. The DRV8846 have the TRI-LEVEL INPUTS…
Part Number: DRV8834 Hi Team,
We use DRV8834 in Indexer Mode and set to 1/8 step.
When we set the nENBL to low, AOUT1 and BOUT1 will keep output the signal even the STEP pin is low. Is it normal?
Attached our sch as below.
Thanks
