DETAILED DESCRIPTION (CONT’D)
SHUTDOWN and RESET
SHUTDOWN and RESET are intended for overriding the
output MOSFET switch via external control logic. The two
inputs are fed through a latch preceding the output switch.
Depending on the logic state of RESET, SHUTDOWN can
be either a latched or unlatched input. The output is off when-
ever SHUTDOWN is low. By simultaneously having SHUT-
DOWN and RESET low, the latch is set and SHUTDOWN
has no effect until RESET goes high. The truth table for these
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 Si9105 is
connected internally to - V IN and is independent of the
SOURCE.
Table 1. Truth Table for the SHUTDOWN and RESET Pins
inputs is given in Table 1.
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.
