Power Outputs
The performance during parallel connection of channels is specified by design and not subject to the production
test. The given factors are maximum values.
All channels at the same junction temperature level.
I_FACTOR
The maximum operating current IDSD,OUTxy(sum) is the minimum âCurrent Shut-down Threshold Lowâ IDSD(low),n(min).
⢠IDSD,OUTxy(sum) = I_FACTOR * SUM[IDSD(low),n(min)] with I_FACTOR = 1.
The typical maximum operating current IDSD,OUTxy(sum) is the âCurrent Shut-down Threshold Typâ IDSD(typ),n(min).
⢠ID,OUTxy(sum) = I_FACTOR * SUM[ID(typ),n]
E_FACTOR
The Maximum Clamping Energy EARxy(sum) of parallel connected channels is defined as follows:
⢠EAR,xy(sum) = E_FACTOR * SUM[EAR,n] at Tj = 150°C and ID = IDnom
ON-Resistance
The typical ON-Resistance RDSon,xy(sum) of parallel connected channels is sum of the typical RDSon RDSon,n(typ)
defined as follows
⢠RDSon,xy(sum) = 1/[1/RDSon,n(typ) + 1/RDSon,n+1(typ)]
