suggestion on high side driver

Other Parts Discussed in Thread: UCC27282, UCD7100, TPIC44H01, TPS4H160-Q1

Hi guys,

I'm looking for a high side driver for an inductive load with these specs:

Vmax=24-42V

I max= 2A

Driving voltage=3.3/5V

overcurrent and temperature protection

Could you please suggest me any of our latest devices?

Thank you in advance.

Best regards,

Adrian

    Hello Adrian,

    For a high side driver which I assume means a floating high side drive and bias, with an input level shifter, we do not have a single channel driver with the overtemperature and current sense functions.

    For the high side driver function I would recommend the UCC27282 half bridge driver which can be used as a high side driver by just connecting the low side driver input (LI) to ground. This driver is a 2.5A/3.5A gate drive current with a switch node rating of 100V so it is compatible with the 24 to 48V which I assume is the power train input range.

    The datasheet can be found here:

    http://www.ti.com/lit/ds/symlink/ucc27282.pdf

    There is a driver with current sense included but it is a low side driver. I will include this for reference. The UCD7100 datasheet can be found here:

    http://www.ti.com/lit/ds/symlink/ucd7100.pdf

    Please confirm if this addresses your questions, or you can post additional questions on this thread.

    Regards,

    Hi Richard,

    just to be more specific, what I'm looking for regarding the driver is an alternative to the infineon-ITS724GFUMA1:

    As a matter of act, the UCC27282 it's quite too performing and expensive; do we have other alternatives?

    Thank you and best regards,

    Adrian

    Hi, Adrian,

    This device is closer to the IFX part, but requires external FETs: tpic44h01

    I am going to ask our colleagues in PSIL to comment if they have a similar device.

    Adrian,

    Unfortunately we do not have anything that goes over 40V on the high side switch side. Is the 42V on the input side a hard limit or would a 40V highside switch work in this application? The competing part that you referenced looks to be only rated to 40V also.

    If we can work around this limit the https://www.ti.com/product/TPS4H160-Q1 would be a good fit for the current limits you specified.

    Hi Timothy,

    thanks for the suggestion, yes the TPS4H160 will work for the customer.

    Now, does the TPS4H160-Q1 have default short circuit protection, or do I have to work on RCL?
    Without RCL the integrated did not handle the short circuit of a channel.
    What value of K (cl) should I use to limit to a value that does not damage the integrated?
    Is the limitation per single channel, or does it add up the four channels (ie: I (cl) is 1A with one valve and 4A with four valves connected)?

    Thank you and best regards,

    Adrian

    Adrian,

    The TPS4H160 does have short circuit protection internal to the device. The CL pin is so that you can set the current limit to a different lower level than the internal level.

    The current limit is per channel by the way.

    Hi guys,

    thanks for the support so far!

    The customer tested the device but it short circuited at 38V on the only one active channel. Do we have any alternative with voltages con tensione ≥40V, automotive, with protection to shorts circuit and temperature?

    Please let me know.

    Thank you and best regards,

    Adrian

    Hello,

    We have devices like our 60V efuse devices that have short circuit protection but you will have to have a flyback diode to handle the inductive energy.
