DESCRIPTION
No external components are required. Reset is maintained active for a minimum of 140msec after VCC rises above the reset threshold. The SE809 has an active-low RESET output. The output of the SE809 is guaranteed valid down to VCC=1V. Both devices are available in a SOT-23 package. ¾ The SE809 is optimized to reject fast transient glitches on the VCC line. Low supply current of 18μA (VCC=3.3V) makes these devices suitable for battery powered applications. ¾ ¾ ¾ Computers Embedded systems Battery powered equipment ¾ ¾ ¾ ¾ ¾ ¾ ¾ SE809 FEATURES
