Soft Start and Disable

Enable / Disable

The device can be disabled by externally pushing COMP / DIS pin under 0.5V (typ). In

disable condition HS and LS MOSFETs are turned off, and a 20

µA current is sourced from

COMP / DIS pin. Setting free the pin, this current pulls it over the threshold and the device

enables again performing a new SS.

To disable the device, the external pull-down needs to overcome 10mA of COMP output

current for about 15

µs. Once disabled, COMP output current drops to 20µA.
