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
μ
A 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
μ
s. Once disabled, COMP output current drops to 20
μ
A.
