8.4 Device Functional Modes
8.4.1 Shutdown / Enable Control
Figure 8-6 shows how to use the UVLO/EN pin for remote shutdown and enable control. Taking the UVLO/EN
pin below its 2.5V threshold (with respect to VEE) shuts off the load current. Upon releasing the UVLO/EN pin
the LM5067 switches on the load current with in-rush current and power limiting. In Figure 8-7 the OVLO pin is
used for remote shutdown and enable control. When the external transistor is off, the OVLO pin is above its 2.5
V threshold (with respect to VEE) and the load current is shut off. Turning on the external transistor allows the
LM5067 to switch on the load current with in-rush current and power limiting.
