Part Number: DRV8899-Q1 Hello Team,
I have a question regarding the current output specification on the DRV8899-Q1 controller chip. On the datasheet I see the "Motor full-scale current (xOUTx)" is limited to 0-1A, however I wanted some clarification on…
Part Number: DRV8899-Q1 Hi,
I need to monitor the current and stop driving the motor when the current is above a threshold level. This threshold must be adjustable, and it is quite lower than the fault triggering current. I could not find a way. Fault…
Part Number: DRV8899-Q1 ・tOL Open load detection time MAX200ms ・IOL Open load current threshold TYP30mA
What percentage of tolerance threshold is guaranteed for each value? If the guaranteed value is an absolute value, please let us know as well.
Part Number: DRV8899-Q1 When a short circuit occurs, the analog current limiting circuit of each FET limits the current flowing through the FET by removing the gate drive.
If this current limit lasts longer than the t OCP time, the FET in that particular…
Part Number: DRV8899-Q1 According to Table 9 in datasheet,the minimum error current of OCP is 1.7A.
Does it mean that the error cannot be reported when the output current of xOUT is less than 1.7A and is short-circuited to the ground?
Part Number: DRV8899-Q1 Hi SIr,
My customer using DRV8899 in camera application.
Currently motor power is 1.5W 、ILIM=300~320mA、V= 5V ；
Motor spec are attach files.
Could you provide DRV889 VREF setting resistors for us? thanks.
Part Number: DRV8899-Q1 Hi Sir,
Would you pls help DRV8899 as below? thanks.
1.VREF and STEP are relative or independent? Will it influence speed? Will it influence current?(Start up will be max. current, increase speed will reduce current?)
