Buck Converter of DRV8301 Reference Voltage
Hello,I am facing problem in the reference voltage of DRV8301 buck conerter.It is regulating the output  (8.6V, while designed for 5V, Rupper =53.6K, Rlower = 10K) at Vsense of 1.34V, instead of 0.8V,...

Hi Rick, Sense resistor value is 0.1ohms and Motor spec 12V@0.35A with P/N 1528-1062-ND (digikey). My guess on this is to do more on settings. During Ideal state A1HS PIN and A2LS are HIGH and LOW...

Hi Pavlin, Please try using decay mode 101 (automixed decay at all times) or 011 (mixed decay at all times). This two settings are good for initial evaluation. 001 (Slow decay for increasing, mixed...

My Nema 17 is scaled to 1.7A. I`m using 0.22 Ohms resistor 5%. I think 1.66 should be fine.. I`ll test the different decay modes and I`ll post the results!

If PWRGD and nOCTW feedback are not used then can leave floating and remove pull up resistor.Short DTC to GND for minimum dead time setting.Internal pull down of M_PWM should be sufficient. Same...

thank you very much for your response. Short DTC to GND for minimum dead time setting So it's not allowed to leave DTC floating if I'm generating the deadtime inside my uC using the 6 PWM inputs?
View ArticleRE: DRV8302 wiring (PullUps, ..)
The DRV8301 has an internal handshake mechanism that cannot be bypassed.This minimum dead time will apply even if the MCU is generating external dead time.

OK! I change the decay mode to 101. It doesn`t help so I change IDRIVEN to 300mA and IDRIVEP to 150mA. I menage to run the engine with 8kHz step frequecy! This means 300 rpm. Is this the maximum rpm...

1) If I short the DTC to GND but use 6 PWM inputs and generate 100ns in my MCU, the DRV will output 100ns deadtime right? 2) leaving the DTC floating and using 6 PWM inputs generating 100ns in my MCU,...
