This is one of those super-secret automotive chips where almost no
information
is available to the public. I'll need authoritative confirmation that
all the
various parameters (b. m, output voltage format, minimum and maximum output
voltage, step size) match mpq7932 exactly. That is rarely the case, so
consider
me skeptic.
Thanks for your time for review. yes, datasheet is not available in
public but Monolithic shall share on request. I confirm all the
parameters are match with mpq7932 datasheet and I have tested the device.

Thanks,
