Product Description
The PI5101 μR
DS(on)
FET
TM
solution combines a high-
performance 5V, 360μΩ lateral N-Channel MOSFET in a
thermally enhanced high density 4.1mm x 8mm x 2mm
land-grid-array (LGA) package to enable world class
performance in the footprint area of an industry standard
SO-8 package. The PI5101 offers unprecedented figure-
of-merits for DC and switching application including
R
DS(on)
x Q
G
, gate resistance (R
G
) and package inductance
(L
DS
) outperforming conventional Trench MOSFETs and
enabling very low loss operation.
Using the PI2001 controller with the PI5101 ultra-low
R
DS(on)
N-channel MOSFET provides very high efficiency
and low power loss during steady state operation. The
PI2001 controller provides an active low fault flag output
to the system during excessive forward current, light
load, reverse current, over-voltage, under-voltage, and
over-temperature fault conditions. The under-voltage
and over-voltage thresholds are programmable via an
external resistor divider.
The PI5101 LGA package is fully compatible with industry
standard SMT assembly processes.

Terminal Description
Vin1 Power source Input #1 or bus input designed to accommodate up to 60A continuous current.
Vin2 Power source Input #2 or bus input designed to accommodate up to 60A continuous current.
1
PI2001 (U1) Fault pin: Monitors U1 fault conditions.
2
PI2001 (U2) Fault pin: Monitors U2 fault conditions.
Vaux1
Auxiliary Input Voltage #1 : supply PI2001 VC power. Vaux1 should be equal to Vin1 plus 5 V or higher. See details in
Auxiliary Power Supply (Vaux) section of the PI2001 data sheet.
Vaux2
Auxiliary Input Voltage #2 : supply PI2001 VC power. Vaux2 should be equal to Vin2 plus 5 V or higher. See details in
Auxiliary Power Supply (Vaux) section of the PI2001 data sheet.
Vout Output M1 and M2 MOSFETs drain connection: connect to the load high side.
Gnd
Return Connection: Ten Gnd connections are available and are connected to a common point, the Ground plane. Input
supplies Vin1, Vin2, Vaux1, Vaux2 and the output load at Vout should all be connected to their
respective local Gnd connection .
