1 / 13 page © Semiconductor Components Industries, LLC, 2010 April, 2010 − Rev. 20 1 Publication Order Number: MAX809S/D MAX809 Series, MAX810 Series Very Low Supply Current 3-Pin Microprocessor Reset Monitors The MAX809 and MAX810 are cost−effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 10 msec of VCC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trimmed by the factory after VCC rises above the reset threshold. The MAX810 has an active−high RESET output while the MAX809 has an active−low RESET output. Both devices are available in SOT−23 and SC−70 packages. The MAX809/810 are optimized to reject fast transient glitches on the VCC line. Low supply current of 0.5 mA (VCC = 3.2 V) makes these devices suitable for battery powered applications. Features • Precision VCC Monitor for 1.5 V, 2.5 V, 3.0 V, 3.3 V, and 5.0 V Supplies • Precision Monitoring Voltages from 1.2 V to 4.9 V Available in 100 mV Steps • Four Guaranteed Minimum Power−On Reset Pulse Width Available (1 ms, 20 ms, 100 ms, and 140 ms) • RESET Output Guaranteed to VCC = 1.0 V. • Low Supply Current • Compatible with Hot Plug Applications • VCC Transient Immunity • No External Components • Wide Operating Temperature: −40°C to 105°C • Pb−Free Packages are Available Typical Applications • Computers • Embedded Systems • Battery Powered Equipment • Critical Microprocessor Power Supply Monitoring VCC VCC VCC PROCESSOR RESET RESET INPUT MAX809/810 GND GND Figure 1.
