Hi Dev,
Dev_Ninja said: 1- Motor current at OUT1/2 is limited to 1A internally, however in the first page of the datasheet shows 1.3A peak to the motor, see picture below. What's the true maximum current that can be supplied to the motor?
1-A peak…
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 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 VSET voltage…
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
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 by…
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 current…
Other Parts Discussed in Thread: DRV8832 , DRV8832EVM I'm designing an MCU interface between a PIC18F67J11 (3.3v) and a DRV8832. My motor is a 6V DC brushed motor. I want to use the iSense capability to limit current to 400 or 500mA. I do not need variable…
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).
