A wide variety of devices (mice, keyboards, cameras,
and printers) can load the USB port. These devices com-
monly connect to the port with cables, which can add an
inductive component to the load. This inductance caus-

load step. The MAX1930 is capable of driving inductive
loads, but avoid exceeding the device ’ s absolute maxi-

small, and the MAX1930 ’ s input includes a substantial

local bypass capacitors, limiting overshoot. If severe
ringing occurs due to large load inductance, clamp the
MAX1930 output below 6V and above -0.3V.

overload protection circuitry activates (see the Thermal
Shutdown section). Wide power-bus planes connected
to IN and OUT and a ground plane in contact with the
device help dissipate additional heat.
