Part Number: DRV8251A Tool/software: HI there,
Couple questions on setting the current limit threshold
1) What is the current consumption on VREF ? Is a voltage divider allowed on this pin ?
2) If I look at the Fig 7-9 in the datasheet, it mentions…
Part Number: DRV8251A Tool/software: Hi All,
The maximum output current specified under Recommended Operating Conditions is 4.1A. This is also listed as one of the key features of the part.
The current mirror mechanism generates a current (I IPROPI…
Part Number: DRV8251A Hi TI,
I'm working on FMEA for coil driver.
I can only assume the worst-case after shorting random pins, so anything can happen. Your assessment could help me with fault diagnostics, maybe identified faults are no longer the…
Part Number: DRV8251A Tool/software: Hi All,
Does anybody have any details of a specification for the input impedance of the Vref pin on the DRV8251A?
Our application requires extremely low shutdown current for all parts of the circuit in some modes…
Part Number: DRV8251A Tool/software: Hello,
Can the DRV8251A support driving huge capacitive loads with the below requirement? Concern is on the current regulation/limitation.
It has a current regulating feature that could be used for limiting the…
Part Number: DRV8251A Tool/software: I'm applying a 15 kHz PWM signal with 20% duty cycle to IN1 of the DRV8251A, while keeping IN2 LOW.
The motor is connected to the output, but I'm not seeing any movement. However, if I connect one motor wire to OUT1…
Part Number: DRV8251A Tool/software: Hi Sir,
we are facing IN1 and IN2 input signals.
Initially we are giving IN1 and IN2 as High (3.3V), and we are giving IN1 or IN2 as low (0.0V) from MCU based on Motor forward or reverse direction requirement.…
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 "No…
Part Number: DRV8251A Tool/software: Hi,
When the customer now detects that the OUT1 and OUT2 of the DRV8251A chip are short-circuited, the Itrip of the chip is triggered first, and then the Iocp is triggered. Previously, when other chips were short…
Part Number: DRV8251A Other Parts Discussed in Thread: DRV8251 Tool/software: Hi Team,
I only found the peak current of DRV8251 in datasheet. Do you know how to calculate the maximize continuous current of H-bridge driver?
