Detailed Description
The MAX5900/MAX5901 are integrated hot-swap con-
troller ICs contained in 6-pin SOT23/TDFN packages.
They allow a board to be safely hot plugged into a live
backplane without causing a glitch on the power-sup-
ply rail. They are well suited for -48V telecom power
systems, allowing a cost-effective, simple, and com-
pact design. The MAX5900/MAX5901 operate from -9V
to -100V to cover the standard telecom voltage range,
and to serve more generalized applications. These
devices require only an external n-channel power MOS-
FET to provide hot-swap control. Figure 1 shows a
functional diagram of the MAX5900/MAX5901.
The MAX5900/MAX5901 control an external n-channel
power MOSFET placed in the negative power-supply
pathway. When power is first applied, the MAX5900/
MAX5901 keep the MOSFET turned off. The MAX5900/
MAX5901 hold the MOSFET off indefinitely if ON/OFF is
held low, if the supply voltage is below the undervolt-
age lockout level, or if the die temperature exceeds
+125癈. If none of these conditions exist for 300ms
(typ), the MAX5900/MAX5901 begin to gradually turn
on the MOSFET. During this turn-on phase, the
MAX5900/MAX5901 slowly enhance the MOSFET,

DRAIN
Drain Sense Input for External n-Channel MOSFET. Connect DRAIN as close as
possible to the MOSFETs drain and use wide circuit traces to assure good
thermal coupling between the MAX5900/MAX5901 and the MOSFET (see the
