Normally the current should not exceed the Nominal Max Current but in some
circumstances it may exceed this value for a short period of time as long as it
does not exceed the Min Current Limit and as long as the duty cycle is low.
The limiting factor is thermal dissipation in the output driver.
The total maximum low side current should not exceed 15A.
The minimum frequency for all outputs is 15Hz (except when used as a
switched output).
Items marked * use a linear current limit, all other outputs shutdown at the
current limit.
