+65V Simple Swapper Hot-Swap Switches
General DescriptionThe MAX5910/MAX5917 are fully integrated hot-swap
switches for positive supply rails. These devices allow
the safe insertion and removal of circuit cards into live
backplanes or ports without causing glitches on the
backplane power-supply rail. They also monitor various
circuit parameters and disconnect the load if a fault
condition occurs, alerting the host with a logic-level
IFAULToutput. The MAX5910/MAX5917 operate over a
+10V to +65V input voltage range. They are designed
to permit hot plugging of an internet appliance such as
an IP phone but are not limited to that application.
During startup, an internal power FET regulates the cur-
rent between the backplane power source and the load
to 280mA for the MAX5910, 567mA for the MAX5917A,
and 420mA for the MAX5917B. After startup, the FET is
fully enhanced to reduce its on-resistance. To ensure
robust operation, the MAX5910/MAX5917 contain built-
in safety features that prevent damage to the internal
FET. They include an enable input, which responds to
positive logic signals (+3.3V or +5V), allowing the host
system to disconnect the load.
The MAX5910/MAX5917 Simple Swapper™ hot-swap ICs
monitor four parameters for fault conditions: undervoltage
lockout (UVLO), power-not-good, zero-current detection,
and thermal shutdown. These devices are available in the
extended temperature range, -40°C to +85°C. The
MAX5910 comes in an 8-pin SO package and the
MAX5917A/B is available in a 16-pin SO package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
