The LTC1731 can be forced into shutdown by floating the PROG pin thus allowing theinterna1 2.5~A current source to pull the pin above the 2.457V shutdown threshold voltage. The DRV pin will then be pulled up to Vcc and turn off the external P-channel MOSFET. The internal timer is reset in the shutdown mode.
