threshold for either voltage monitor to be repro-
grammed to meet special needs or to fine-tune the
threshold for applications requiring higher precision.
The Watchdog Timer provides an independent protec-
tion mechanism for microcontrollers. When the micro-
controller fails to restart a timer within a selectable time
out interval, the device activates the WDO signal. The
user selects the interval from three preset values. Once
selected, the interval does not change, even after
cycling the power.
The device features a 2-wire interface and software
protocol allowing operation on an I

C
bus.

V2 Voltage Monitor Input.
LOW. This input can monitor an unregulated power supply with an external resistor divider or can
monitor a second power supply with no external components. Connect V2MON to V
when not used.The V2MON comparator is supplied by V2MON (X40010/11) or by V
(X40014/15).
RESET Output.
(X40011/15) This is an active LOW, open drain output which goes active when-
ever V
CC
falls below V
TRIP1
. It will remain active until V
thereafter.
RESET Output.
(X40010/14) This is an active HIGH CMOS output which goes active whenever

This open drain output goes LOW when V2MON is less than V
TRIP2
