DRI0050 for powering magnetic coil
Hans.Frobel 2024-08-27 07:11:54 90 Views1 Replies Hello. Can the DRI0050 driver be used to power a magnetic coil in an automotive transmission (for differential lock)? Specs of the coil is about 12v and 4A, PWM duty cycle from 0 to about 75%. Frequency between 300Hz and 2000Hz. Can the driver handle the ambient temperatures (-20° to +60°) and vibrations, humidity etc.? And should a flyback diode be used in conjunction with the coil in this case?
The operating voltage range of DRI0050 is 5~24VDC, it can support up to 10A, PWM duty cycle is 0~100%, and adjustable frequency range is 183Hz ~ 46875Hz. so we think the above is not a problem.
For environmental issues, the DRI0050 has an operating temperature of -40~85℃ and an operating temperature of 0~95% without condensation. Although we don't have any relevant test for vibration, the PCBA doesn't use any package like BGA which is easy to fall off, so we think it has good anti-vibration performance.
As for the flyback diode and coil issues, we are sorry that we can't give effective suggestions. You can refer to the schematic in wiki to make a judgment.
