19

20. Picor Cool-Swap: PI2211 with True-SOA
› True-SOA
– Ensures safe DC and transient MOSFET performance by emulating the
MOSFET junction temperature rise via a internal digital processor
– Emulation of the MOSFET thermal performance is possible with the use
of the MOSFET manufacturers’ transient thermal impedance curves
– The PI2211 the adapts its control, start-up, or thermal cycling to that
specific MOSFET
– True-SOA ensures maintaining a MOSFET within the actual SOA of the
device, accounting for both DC and transient operation
20

21. Picor Cool-Swap: PI2211 with True-SOA
Input current
monitored and
Instantaneous
› MOSFET will operate in linear
power measured limit or shutdown mode for
one of four reasons:
Internal PI2211
True-SOA™
– If a 60 C temperature rise is emulated
Emulator than the PI2211 will shutdown the
MOSFET and attempt to restart when
temp drop of 39 C is emulated. OR…
MOSFET junction
temperature emulated – Current exceeds the circuit breaker
threshold. OR…
RSOAS – Start-up current limit exceeded. OR…
RSOAR – OV / UV tripped
RSOAT
Three resistors program the True-SOA™ Emulator with the
MOSFET thermal characteristics
Adapts PI2211 control / start-up to that specific MOSFET
21

22. Picor Cool-Swap: PI2211 with Glitch-Catcher
› Prevents over voltage transient spikes
caused by the energy stored in the
parasitic inductance of the input
power path in response to a rapid
interruption of the forward current
after a circuit breaker event
› Acts as an active snubber
› Mitigates the need for large external
protection components by shunting
the energy through the MOSFET to
the low impedance load
