Hi Pratik,
The current can be measured/observed by monitoring the ISENSE pin. When the voltage on pin ISENSE exceeds VILIM (0.2 V), overcurrent is detected. The RSENSE resistor should be sized to set the desired ILIMIT level.
RISENSE = 0.2 V / ILIMIT…
Hey Ram,
Your calculations look good to me!
Bulk capacitance looks good. 100kΩ nFAULT pull-up is more than we typically see but will be fine.
You can order an EVM if you want to test it out before making your own board: DRV8832EVM Evaluation board…
Hi Tim,
Yes, this can be assumed. Once the device is awake, FAULTn will assert for undervoltage, overcurrent, overtemperature, and potential stall conditions as described in section 7.3.5 of the datasheet.
If you want to verify your application further…
Hi Chinnu,
There is an evaluation module, the DRV8832EVM. The schematics and layout are available online.
There is also a reference design based on the DRV8832EVM, www.ti.com/.../TIDA-00141
Hi Mitchell,
The DRV8837C allows continuous PWM adjustment while the DRV8832 allows continuous VSET adjustment.
What is the desired PWM input frequency for the DRV8837C?
The DRV8832 is designed to produce a voltage to the motor that is 4x the…
Part Number: DRV8832 Hi team,
I would like to know DRV8832 regards to the fault triggered by current limit condition.
I am using DRV8832EVM to verify whether the fault can triggered by current limit condition. For the experiment, I stop the motor…
Other Parts Discussed in Thread: DRV8832EVM , DRV8832 Hello Team,
I have a customer who is working with the DRV8832EVM and has a question. The customer is using VREF and a potentiometer to set the VSET to set the driving voltage.
"What is the maximum…
Hi Lee,
The control logic for IN1/IN2 is shown on page 7 of the datasheet. We also have an EVM you can purchase to evalutate the part PN = DRV8832EVM.
For forward you would hold IN1 High and PWM IN2 (opposite for reverse).
