Part Number: DRV8251A Other Parts Discussed in Thread: DRV8251EVM Hello, I'm planning to use the DRV8251A to drive a BDC motor, replacing the DRV8432. On the previous version of the schematic (not my design)
it shows snubber circuits, with a note…
Hi Jagdish,
From a design perspective the schematic seems ok.
As long as the DRV8251A is operated within recommended specifications, it will be fine.
As I mentioned earlier I would suggest simulating or testing the layout first with the DRV8251AEVM to…
Part Number: DRV8251A Hi Team,
In datasheet, the typ value of Ttsd is 175℃, and the maximum temperature of Tj is 150℃. The triggering condition for overheating protection is Ttsd > Tj. When the chip temperature is higher than Tj, the chip may be damaged…
Part Number: DRV8251AEVM Other Parts Discussed in Thread: DRV8251A Hi,
We are testing the DRV8251A on a brushed DC motor (24V 4A). The development board has two potentiometer to set the motor speed in both directions.
Our problem is; the motor is turning…
Part Number: DRV8251A Is VREF a logic input? I understand that the internal impedance is high, and it is not a port where current flows in, but there is no current information or resistance information, so please check it.
Also, is it possible to reduce…
Part Number: DRV8251A In one mode, I am using this as a single output high side driver by just driving IN1. If the input a frequency below ~460Hz, the driver will start adding the 50uS sleep delay, which affects the accuracy of the duty cycle. I can add…
Part Number: DRV8251A For small brushed motors -
Ignoring cost, efficiency, and solution size, what control scheme will provide the best variable speed operation down to speeds well below the motor's nominal RPM:
-- a variable voltage or -- PWM at…
Part Number: DRV8251A I have a puzzling problem with DRV8251A.
My connections are really simple - VREF, IN1, IN2, IPROPI are connected straight to MCU pins with no shared connections. Resistor to ground on IPROPI. A 12V DC motor rated at 2A, is connected…
Part Number: DRV8251A Hi team,
I’m configuring the DRV8251A peripheral circuit to get correct current regulation after paralleling with my customer, e.g., setting each Itrip=1.5A, and need the total current regulated @ 3A. However, they have get the result…
