ZXCM209JF-voltage detector
The three terminals ZXCM209/210 supervise the power supply circuit for the display to supply the microprocessor and digital system. They provide a high performance economical solution when used with 5V, 3V or lower supply circuits. Resets threshold supply voltages suitable for various operations. These devices provide a reset signal whenever the supply voltage falls below a preset threshold, keeping it asserted, a minimum delay time of 140ms after the supply has risen above the reset level. "The ZXCM209 has an active-low reset output (which is guaranteed to supply supplies down to 1V in the correct state), while the ZXCM210 has an active-high reset output. The reset comparator has built-in hysteresis to prevent unstable operation and is designed to Ignore supply transients. Low supply current (typically 2µA) makes the ZXCM209/210 ideal for use in portable devices. They are available in a 3-pin SOT23 industry standard surface mount package pinout.
