1 / 7 page 3 PIN MICROPROCESSOR RESET MONITORS FSP2200 2007-2-8 1/7 PIN CONFIGURATION (Top View) Pin Name Function 1 GND Ground reference 2 RESET Active-low output. RESET remains low while VCC is below the reset threshold, and for a reset timeout period after VCC rises above the reset threshold. 3 VCC Supply voltage (typ.) TYPICAL OPERATION CIRCUIT GENERAL DESCRIPTION The FSP2200 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 FSP2200 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 FSP2200 ideal for use in portable equipment. The FSP2200 are available in SOT323-3L or SOT23-3L packages. FEATURES Precision VCC Monitor for 2.5 V, 3.0V, 3.3 V, and 5.0 V Supplies Fully Specified Over Temperature Available in Three Output Configurations Push-Pull RESET Output 140ms min Power-On Reset Pulse Width 12µA Supply Current Guaranteed Reset Valid to Vcc=+1V Power Supply Transient Immunity No External Components SOT323-3L and SOT23-3L Packages APPLICATIONS Computers Controllers Intelligent Instruments Critical MPU and MPU Power Monitoring Portable/Battery-Powered Equipment Automotive 3 1 2 RESET GND VCC |
