PRODUCT DESCRIPTION
This evaluation board allows the ADM1170, ADM1171, and
ADM1172 to be easily evaluated. These parts are hot swap
controllers with enable input and gate pin output to drive an
external FET. The hot swap control circuitry allows the boards
to be safely inserted and removed from a live 1.6 V to 16.5 V
backplane. The parts provide precise, robust, current-limiting
protection against transient and nontransient short circuits as
well as undervoltage and overcurrent conditions.
In addition to the standard hot swap functionality, the ADM1170
has an additional supply pin that allows voltage monitoring on
a supply rail to go as low as 1.6 V. The ADM1171 features a
current sense output (CSOUT) pin. The voltage on the CSOUT
pin represents the voltage drop across the sense resistor gained
up by a factor of 20. Both ADM1170 and ADM1171 feature a
soft start function that provides the user with a capacitor pro-
grammable ramping reference to the internal current-sense
comparator. This provides a linearly increasing current limit at
startup at a rate set by the soft start capacitor (C
SS
), which helps
to reduce and limit large inrush currents. The ADM1172 features
a power-fail comparator. The voltage on the PFI pin is compared
with an internal 0.6 V reference, and the output of this
comparator is presented on the PFO pin.
All these devices are available in two options: the ADM117x-1
with automatic retry for overcurrent fault and the ADM117x-2
with latch-off for an overcurrent fault. Toggling the ON (ON-
CLR
) pin resets a latched fault. All parts are packaged in an
8-lead TSOT.
Order codes for evaluation kits are shown in the Ordering
Guide. (Pinouts and detailed package drawings can be found
in the individual product data sheets.)
EVALUATION BOARD DESCRIPTION
The ADM1170/ADM1171/ADM1172 hot swap controller
evaluation board contains all the necessary components for
evaluating all features of the devices. This board requires a
bench power supply of between 2.7 V and 16.5 V, connected
through J1 and J3 or, alternatively, through the corresponding
connectors on J4.
This board is capable of evaluating the ADM1170, ADM1171,
and ADM1172 parts by simply changing certain connectors to
suit specific evaluation plan.
