Enable / disable
The device can be disabled by externally pushing COMP / DIS pin under 0.5 V (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 10 mA of COMP output
current for about 15
μs. Once disabled, COMP output current drops to 20μA.
