  • Forum Post: DRV8301 faulting immediately on start-up

    Joe Hlebasko
    I am experimenting with the DVR8301-HC2 kit. I was able to work my through the basic GUI and then the Build steps with the code getting my motor to spin at the right steps. I started to add some code to the existing BLDC_Int project to read the potentiometer to set the speed. I started getting a driver...

    Dear All, I am debugging using customer board( TMS320F28035 + DRV8302 : DC bus voltage: Max 32V, Phase Current: Max 20A, RPM: Max 3000RPM, PWM= 15kHz, Servo Motor). Unfortunately we found "FAULT" signal as soon as we operated. (The signal pattern of "FAULT" pin is "...

  • Forum Post: DRV8302 and NTSOA

    Mark Berry
    Hello Forum Experts, I wondered if there is any further information available to define the Negative Transient Safe Operating Area for the DRV830x parts. There is a single line comment in the data sheet that says "High side gate drive will survive negative output from bridge up to -10V for...

  • Forum Post: DRV8301/2 dead time setting in 3-input mode.

    Shane Colton
    Does the deadtime setting configured with a resistor on the DTC pin of the DRV8301/8302 also apply in 3-input mode? There is a note in the DRV8301 datasheet that says: "PWM with three independent inputs. PWM control high side gates only. Low side is complementary to high side gates with minimum...

  • Forum Post: Re: DRV8301/2 dead time setting in 3-input mode.

    Shane Colton
    Okay, thanks. I interpreted that as saying that external dead time set by the microcontroller (on INH and INL pins) would be observed as long as it was longer than the DTC resistor setting. So, if there was a 1us gap between INH high-to-low transistion and INL low-to-high transition, it would override...

    I am having some difficulty reading the fault from the status registers of the DRV8301, and I'm looking for some guidance. Here is my setup: Code Composer Studio version 5.2.1.00018 controlSUITE v3.0.0 Hardware: DRV8301-HC-C2-KIT (DRV8301-HC-RevC1-RELEASE.pdf) with TMDSCNCD28035ISO controlCARD...

    Rachel Coulter
    Does TI have any app notes/reference designs that would be applicable to higher power (100-1500W) level motor drive designs for the DRV8301? Thanks, Rachel

  • Forum Post: RE: DRV8301 3 phase pre driver with Integrated Buck Regulator

    SUnderwood1
    Ok Great. The DRV8301 data sheet block diagram indicates the buck regulator power input (PVDD2) is completely independent from the motor driver power in (PVDD1). So I can run the buck regulator on PVDD2 with the rest of the driver unpowered (PVDD1) ? correct? Is there any issue if the buck regulator...

    David Petticord
    We have a motor controller design based on the DRV8301 and an Atmel uC . It works as expected for supply voltages below 30 volts. However when we try to drive a motor with 36 volts it goes into fault lockups (intermittently). Up until now we have been using the default settings (no need to use...

  • Forum Post: DRV8301 - 4 quadrant control

    Matthias Stark1
    Hi! Which TI motor drivers can be used to realize four-quadrant control of permanent magnet/brushless motors? In particular, it would be interesting if the DRV8301 could be used for that application?! Thanks a lot!

  • Forum Post: DRV8301 PVDD max voltage ramp rate

    Derek King1
    According to the datasheet the max PVDD ramp rate is 50V/ms. It also specifies that PVDD1 is completely independent of PVDD2. In a another post it is explained that a faster voltage ramp will cause logic problems, but not damage . http://e2e.ti.com/support/applications/motor_drivers/f/38/p/200671/849287...

    Derek King1
    The datasheet for the DRV8301 states the gate driver "Support up to 200kHz switching frequency with Qg(TOT)=25nC or total 30mA gate drive average current". In this statement, what is Qg(TOT)? 1. The Qg for a single FET? At 200kHz each highside and lowside FET can have a Qg of 25nC. 2...

    Pete Owen
    Hello, I recently completed a test that required control of eight BLDC motors (48V/5A/10k RPM) using eight DRV8301-HC-C2-KIT eval boards running lightly modified Instaspin software and a Stellaris Launchpad to control them all over SPI. This worked well, but required a huge box, so the next stage of...
