GENERAL DESCRIPTION
The ADM1070 is a negative voltage hot swap controller that
allows a board to be safely inserted and removed from a live
48 V backplane. The part achieves this by providing robust
current limiting, protection against transient and nontransient
short circuits and overvoltage and undervoltage conditions. The
ADM1070 typically operates from a negative voltage of up to
80 V and can tolerate transient voltages of up to 200 V.
In-rush current is limited to a programmable value by control-
ling the gate drive of an external N-channel FET. The current
limit can be controlled by the choice of the sense resistor,
R
SENSE
. Added control of the in-rush current is provided by an
on-chip timer that uses pulsewidth modulation to allow the
maximum current to flow for only 3% of the time. An autorestart
occurs after a current limit timeout. After seven successive
autorestarts, the fault will be latched and the part goes into
shutdown with the result that the external FET is disabled until
the power is reset.
The ADM1070 also features single-pin undervoltage and over-
voltage detection. The FET is turned off if a nontransient
voltage less than the undervoltage threshold, typically 36 V, or
greater than the overvoltage threshold, typically 77 V, is detected
on the UV/OV Pin. The operating voltage window of the
ADM1070 is programmable and is determined by the ratio R1/R2.
Time filtering on the undervoltage and overvoltage detection
and current limiting is programmable via the TIMER Pin. An
external capacitor connected between the TIMER Pin and V
EE
determines the undervoltage/overvoltage time filter and the
timeout in current limit. If the pin is tied to V
EE
, the time filter
values and the current limit timeout revert to default figures.
The ADM1070 is fabricated using BiCMOS technology for mini-
mal power consumption. The part is available in a small
6-Lead SOT-23 package.
