The LSP2200 is a microprocessor supervisory circuits used to monitor the power supplies in MPU and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V powered circuits These curcuits perform a single function: they assert a reset signal whenever the Vcc supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after Vcc has risen above the reset threshold. Reset thresholds suitable for operation whit a variety of supply voltages are available. The LSP2200 have push-pull outputs, an active-low RESET output. The reset comparator is designed to ignore fast transients on Vcc, and the outputs are guaranteed to be in the correct logic state for Vcc down to 1V. Low supply current makes the LSP2200 ideal for use in portable equipment.
The LSP2200 is available in SOT23-3L package.
