Most MOSFET data sheets have an RDSON specification
with typical and maximum values but no minimum value.
Assuming a normal distribution with typical as mean, the
minimum value can be estimated as

The LTC4213 gives higher gate drive than the manufac-
turer specified gate drive for RDSON. This gives a slightly
lower RDSON than specified. Operating temperature also
modulates the RDSON value.
Example Current Limit Calculation
An Si4410DY is used for current detection in a 5V supply
system with the LTC4213 VCB at 25mV (ISEL pin grounded).
The RDSON distribution for the Si4410DY is
Typical RDSON = 0.015 = 100%
Maximum RDSON = 0.02 = 133.3%
Estimated MIN RDSON = 2 15 – 20 = 0.010 = 66.7%
The RDSON variation due to gate drive is
RDSON @ 4.5VGS = 0.015 = 100% (spec. TYP)
RDSON @ 4.8VGS = 0.014 = 93% (MIN VGSMAX)
RDSON @ 7VGS = 0.0123 = 82% (NOM VGSMAX)
RDSON @ 8VGS = 0.012 = 80% (MAX VGSMAX)
