MAX821/MAX822 4-Pin µP Voltage Monitors with Pin-Selectable Power-On Reset Timeout Delay General Description
... While designed to issue a reset to the microprocessor (µP) during power-up, power-down, and brownout conditions, the MAX821/MAX822 are relatively immune to short-duration, negative-going VCC transients (glitches). Figure 1 shows the maximum transient duration vs. reset comparator overdrive for which ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
