VERY LOW POWER MICROPROCESSOR RESET DEVICES
ZXCM209
ZXCM210
DESCRIPTION
The ZXCM209/210 are three terminal supervisory
circuits used to monitor the power supplies in
microprocessor and digital systems. They provide a
high performance economical solution when used
with 5V, 3V or lower powered circuits. Reset
thresholds suitable for operation with a variety of
supply voltages are available.
These devices provide a reset signal whenever the
supply voltage falls below a preset threshold, keeping
it asserted for a minimum delay period of 140ms after
the supply has risen above the reset level. The
ZXCM209 has an active-low RESET output (which is
guaranteed to be in the correct state for supplies down
to 1V), while the ZXCM210 has an active-high RESET
output.
The reset comparator has in built hysteresis to prevent
erratic operation and is designed to ignore supply
transients. Low supply current (typically 2µA) makes
the ZXCM209/210 devices ideal for use in portable
equipment. They are available in a 3-pin SOT23
surface mount package with an industry standard
pinout.
