Part Number: DRV8256
Tool/software:
Hello,
I just wanted to clarify input functionality in DRV8256.
My application will be brushed DC motor driver while Inputs are discrete, not based on PWM. It's just either just ON for awhile then OFF for awhile…
Part Number: DRV8256 Tool/software: Hi team,
I have questions regarding DRV8256 as follows: 1. For PWM control, is it mandatory to use IN1/IN2 pins instead of EN/PH pins? Would it not work properly if PWM is applied to the EN pin and direction is controlled…
Part Number: DRV8256 Tool/software: Hi team my customer is using DRV8256 and they did the stalling test . The problem is that if they set the ITRIP value as 4.16A , the stalling will be detected after around 20s But when the Itrip is set as 7.58A , the…
Part Number: DRV8256 Other Parts Discussed in Thread: DRV8235 , Tool/software: Hi team, I facing different issues with TI motor driver chips. First i selected DRV8235 to drive A linear actuator 24V 3A. While controlling actuator movement the chip burned…
Part Number: DRV8256 Other Parts Discussed in Thread: DRV8262 Tool/software: Hello,
According to this thread , the DRV8256 family does not require an nSLEEP reset pulse.
Could you clarify whether this also applies after OCP and OTSD? Specifically…
Part Number: DRV8256 Other Parts Discussed in Thread: DRV8251EVM , DRV8251 , DRV8210 , DRV8873 , DRV8243-Q1 We are designing motor circuits using the DRV8256. Which circuit should I use: high-side or low-side to measure the current flowing through the…
Part Number: DRV8256 Team, My customer is thinking to use DRV8256 between 0.1A ~ 0.5A. I have some questions here;
1. Does DRV8256 have capability to drive BDC motor at such small current? 2. If yes, what is Itrip accuracy between 0.1A ~ 0.5A? There…
Part Number: DRV8256 Team,
In case that Itrip set at low current, such as 100mA, and TOFF set to 0, the Ivalley can be calculated as follows;
Ivalley = 19mA + 99% * 100mA = 118mA
Ivalley is greater than Itrip. What happens at this kind of cases…
Part Number: DRV8256 HI TI,
My question is regarding the chips Thermal Fault output. When driving the chip with PWM, in any direction, the chip is getting hot and not latching the thermal fault. The output driving current seems to degrade as the chip…
