The LX7001 is an improved
undervoltage sensing circuit specifi-
cally designed for use as a reset
controller in microprocessor-based
systems. Today's complex miniaturized
systems present difficult challanges to
the system designer such as overcom-
ing spurious noise problems. The
LX7001 is optimized for systems that
must be tolerant of high-speed power
supply glitches caused by high-speed
logic transitions and similar switching
phenomena. The LX7001 offers a
unique stage that couples glitch
immunity with a micropower, ultra-
stable band-gap reference for preci-
sion sensing of undervoltage condi-
tions. It offers the designer an

economical, space-efficient solution
for low supply voltage detection
when used in combination with a
single pull-up resistor. Adding one
capacitor offers the functionality of a
programmable delay time after power
returns. Additionally, the LX7001
offers excellent temperature stability.
A high-quality trimmed voltage
reference and bias circuit permit very
accurate and repeatable undervoltage
sensing. The remaining blocks
consist of a comparator with hyster-
esis, high current clamping diode and
open collector output stage capable
of sinking up to 60mA. The
LX7001's RESET output is specified to
be fully functional at V
