ZXCM210

VERY LOW POWER MICROPROCESSOR RESET DEVICES

DESCRIPTION

APPLICATIONS

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.

Power supplies

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.

APPLICATION CIRCUIT

v_cc

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.
