high and the DISCON pin is set to its high-impedance
state. After 130ms, the DRV pin is pulled low by the
MAX1906, exiting the test mode. The time period of
130ms has been chosen not to stress the three-terminal
protection fuse if an external MOSFET is used to blow the
fuse. The OUT pin is not affected by the test mode. See
the timing diagram for the test mode in Figure 7.

Entry into test mode is ignored if the MAX1906 has
detected an overvoltage condition and has activated
the 2.1s delay. Test mode remains disabled until the
MAX1906 exits the overvoltage condition. The
MAX1906 continues normal operation upon exit from
the test mode.
