ADV 3-pin microprocessor resets The ADV809 and ADV810 are cost–effective system supervisorcircuits designed to monitor VCC in digital systems and provide a resetsignal to the host processor when necessary. No external componentsare required.The reset output is driven active within 20 sec of VCC fallingthrough the reset voltage threshold. Reset is maintained active for aminimum of 140msec after VCC rises above the reset threshold. TheADV810 has an active–high RESET output while the ADV809 hasan active–low RESET output. The output of the ADV809 isguaranteed valid down to VCC = 1V. Both devices are available in aSOT–23 package. The ADV809/810 are optimized to reject fast transient glitches on Features Precision VCC Monitor for 3.0V, 3.3V, and 5.0V Supplies 140msec Guaranteed Minimum RESET, RESET Output Duration RESET Output Guaranteed to VCC = 1.0V (MAX809) Low 17A Supply Current VCC Transient Immunity Small SOT–23 Package No External Components Wide Operating Temperature: –40C to 85C Typical Applications Computers Embedded Systems Battery Powered Equipment Critical P Power Supply Monitoring TYPICAL APPLICATION DIAGRAM VCC ADV809 ADV810 RESET RESET GND VCC PROCESSOR RESET INPUT RESET INPUT GND ADV809/810 SOT–23 GND 1 RESET 2 (RESET)** 3 VCC SSOOTT–2233** NOTE:*SOT–23 is equivalent to JEDEC (TO–236) ** RESET is for ADV809 ** RESET is for ADV810 ORDERING INFORMATION Device Package Shipping ADV809xTR SOT–23 3000 Tape/Reel ADV810xTR SOT–23 3000 Tape/Reel NOTE: The ”x” denotes a suffix for VCC threshold – see table below Suffix L M J* T S R Reset VCC Threshold (V) 4.63 4.38 4.00 3.08 2.93 2.63 NOTE: *J version is available for ADV809 only 1/5 www.advsemi.com Ver.0.10 ADV ADV809/810 Absolute Maximum Ratings Pin Terminal Voltage with Respect to Ground VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3V to 6.0V RESET, RESET . . . . . . . . . . . . . . . . . . . . . . . . . –0.3V to (VCC + 0.3V) Input Current at VCC . . . . . . . . . . . . . . . . . . . 20mA Output Current: RESET, RESET . . . . . . . . . 20mA Rate of Rise at VCC . . . . . . . . . . . . . . . . . . . . 100V/μs Power Dissipation (TA= 70°C) . . . .. . 320mW (Derate 4mW/°C above 70°C) Operating Temperature Range . . . . . –40°C to 105°C Storage Temperature Range . . . . . . . –65°C to 160°C Lead Temperature (soldering, 10 sec) . . . . . 300°C These are stress ratings only and functional operation is not ADVlied.Exposure to absolute maximum ratings for prolonged time periods mayaffect device reliability Electrical Characteristics Unless otherwise noted VCC is over the full voltage range, TA = –40°C to 105°C.
