Part Number: DRV8705-Q1
Hi TI Team,
Iam a Master Student using 8705s-q1 i have doubt what is difference in Mode-2 (PH/EN Control) & Mode-3 (PWM Control) controls in IC.
I want to use Mode-3 how to control forward/reverse drive is my below understanding correct (just elaborate and can tell me...) & what is latched mode of fault.
IN1 IN2 Drive
0 (PWM 0% duty) 1 (PWM >0% duty) Reverse1 (PWM >0% duty) 0 (PWM 0% duty) Forward
Please Respond ASAP.
Yes. In PWM mode, host controller can control the INx to make winding current going forward or reverse. That drives the motor going forward or reverse.
“Latched mode” means the output keeps disable even the failure condition disappears.

In reply to Wang5577:
My one more doubt whether one input IN1 own should be 0% duty other input IN2 some variable duty is it correct can you elaborate for mode 3 pwm control
Thanks in advance..
In reply to Sravan G:
Yes. When IN2 is driven a variable duty cycle by the host controller, IN1 should be low (0% duty). So, the current flows from OUT2 to OUT1.
Thanks Wang Li for your support
