Part Number: DRV8307 We are using the DRV 8307 to interface to reciprocating piston pump.DRV 8307 is controlled by the FPGA.During testing we follow these steps:
1. Program the FPGA
2. Send 20% PWM-DC input to the DRV8307.We see the pump running at 20…
I have built a couple hundred board and once in a while I have a chip smoke and not sure what is causing it. and it happens after its been running for a while.
it looks to be by the power sense pin. has anyone else had this happen?
Other Parts Discussed in Thread: DRV8307 , DRV8307EVM Hi,
I am trying to drive bldc motor with drv8307 ic on my own board. When i drive motor with DRV8307EVM board, the motor draws its normal current 1.45A. But when i drive motor with my own board the motor…
Other Parts Discussed in Thread: DRV8307 , DRV8308 Dear sir,
l have questions about OCP function drv8307/drv8308.
1.Does Drv8307/8 measure the voltage across VM and pin-U to determine whether the high side MOSFET-U is over current or not?
If it is in this…
Other Parts Discussed in Thread: DRV8308 , DRV8307 We are building a product that requires bypassing the DRV3807's rotor lock detection. The datasheet does not mention a way to do this, nor does it describe the rotor lock detection criteria well enough…
Other Parts Discussed in Thread: DRV8307 , DRV8307EVM , CSD88537ND Hi there,
I'm using the DRV8307 to drive a 24V rated BLDC motor. I was able to drive it using the DRV8307EVM but i'm having some issues when trying to drive the same motor on my board.…
Other Parts Discussed in Thread: DRV8307 , DRV8308 Is the 30mA gate current internally limited? The user manual for the EVM marks the gate resistor as optional, so presumably they're not needed solely to limit drive current, just for slowing switching for…
Part Number: DRV8307 We are using the 8307 driver to interface to a reciprocating piston pump. To turn on the pump when we change the PWM DC from 0% to 20% or 0%to 50 % or 0% to 100% or 0% to any %, faultn is asserted low for approx. 160 us .We want to…
Other Parts Discussed in Thread: DRV8307 , DRV8308 Dear Sir,
1. Suppose I add a RC filter on ISEN pin to filter the R-sense noise. My question is that: when low side gate drive turn off the low side MOS, there is a large current from the low side MOS-gate…
