Hot Swap Solution Meets AMC and MicroTCA Standards
Design Note 437
Vladimir Ostrerov
Introduction
The LTC В®4223 is a dual Hot Swapв„ў controller that meets
the power requirements of the Micro Telecommunication
Computing Architecture (MicroTCA) speciп¬Ѓcation recently
ratiп¬Ѓed by the PCI Industrial Computer Manufacturers
Group (PICMG). The LTC4223 monitors 12V load current by sensing
voltage across an external resistor and outputs a groundreferenced voltage (at the 12IMON pin) proportional to
the load current. It also provides separate power-good
outputs for the two supplies and a single, common fault
output. Additional features include card detection and
independent control of the two supplies. The LTC42231 latches off after a circuit breaker fault timeout expires
while the LTC4223-2 provides automatic retry after a
fault. A fault on the 12V supply shuts down only the 12V
path, leaving the 3.3V auxiliary power available for system
management functions. A fault on the 3.3V AUX supply
shuts down both supplies. The LTC4223 includes an internal pass FET for the 3.3V
auxiliary supply and a driver for an external N-channel
pass FET for the 12V payload supply. Inrush current for
both supplies is controlled: the auxiliary supply has a
п¬Ѓxed 240mA active current limit and the 12V ramp rate …

DESIGN FEATURESвЂ‰L Compact Hot Swap Solution Simplifies
Advanced Mezzanine Card Design
by Chew Lye Huat
Introduction
Advanced Mezzanine Cards (AdvancedMC) are 80W add-on modules
that are central to the extensibility
of MicroTCA and AdvancedTCA high
availability systems. AdvancedTCA targets high capacity, high performance
applications whereas MicroTCA serves
smaller, cost-sensitive applications
with less demanding requirements.
Unlike other mezzanine modules,
which are bolted on, AdvancedMC
modules can be inserted into a live
backplane improving serviceability
and flexibility. The LTC4223 offers a compact and
comprehensive Hot Swap solution for
Advanced Mezzanine Cards, providing
inrush control, overcurrent protection
and supply monitoring. It detects
board insertion and extraction, allowing the 12V and 3.3V auxiliary power
supply to be delivered in a controlled
manner without damaging the connector. The LTC4223 provides a current …
