Vishay Siliconix
DETAIL DESCRIPTION (CONT’D)
Both pins have internal current source pull-ups and can be
left disconnected when not in use. An added feature of the
current sources is the ability to connect a capacitor and an
open-collector driver to the SHUTDOWN pin to provide vari-
able shutdown time.
Output Switch
The output switch is a 7 Ω , 200 V lateral DMOS transistor.
Like discrete MOSFETs, the switch contains an intrinsic
body-drain diode. However, the body contact in the Si9108 is
connected internally to - V IN and is independent of the
SOURCE.
