Nikolai,
Yes different duty cycle would be used to increase the current out to the motor.
I would recommend ordering an EVM and using that as your starting point. A driver like the DRV8323 (useful for motors up to ~30V) has a nice EVM that you could setup…
Part Number: DRV8332-HT Other Parts Discussed in Thread: DRV8332 Hi support team,
I have read your explanations about disabled thermal shutdown in DRV8332-HT that date back to about 4 years ago, with the intention to make corrections to the confusing…
Part Number: DRV8332 Other Parts Discussed in Thread: DRV8312 Dear Support team I'm working with DRv8332 and DRV8312 evaluation KIT on sensoreless BLDC application : I have issue that my system working with some motor and not working properly with…
Part Number: DRV8332 Sense resistors are mentioned in 8.4.1, pictured in Figure 8 typical application diagram and described once again in 9.2.1.2.5 Are these user-specific sense resistors or are they required for the DRV8332's operation on its own? Are…
Part Number: DRV8332 Hi TI,
I used the part DRV8332 as the BLDC driver, but the efficiency is just about 60%. the motor current is about 2A (48V), can you help give me some suggestion how to improve the system efficiency。the magnetic pole pairs of our…
Part Number: DRV8332 I need to connect the chip DRV8332 with a micro-controller which generating (complementary low side fixed PWM scheme ) and the illustrating in the data sheet only shows a bipolar PWM scheme, my question is that it's valid to use this…
Part Number: DRV8312 Other Parts Discussed in Thread: DRV8332 , Hi
According to the datasheet of DRV8312 and DRV8332, it is mentioned that PWM frequency can accept up to 500kHz.
I want to ask about this spec.
-Is there a any constraint about PWM minimum…
Part Number: DRV8312 Other Parts Discussed in Thread: DRV8332 , Hi
I have a question about DRV8312 and DRV8332 power up and power down sequence.
According to the datasheet, it mention that there are no requirement about power up and down sequence.
But it…
Part Number: DRV8312 Hi
According to the DRV8312's datasheet, in 10.3.2 VDD Pin mentioned that "A 22-μF to 47-μF capacitor should be placed on VDD pin."
Is this capacitor mean electrolytic capacitor?
Parts supplier supply this capacity…
Part Number: DRV8332 Other Parts Discussed in Thread: DRV8320 , MSP430F5529 Hi everyone,
I am trying to use DRV8332 to control BLDC motors. I don't have much knowledge of controlling BLDC, so I have some questions:
-------1/ In figures 13 and 14 in…
