19-1933 Rev 2; 12/05 3-Pin, Low-Power µP Reset Circuits MAX6800/MAX6801/MAX6802 General Description Features The MAX6800/MAX6801/MAX6802 microprocessor (µP) Ultra-Low 0.7V Operating Supply Voltage supervisory circuits monitor the power supplies in 2.85Vto 5.0V µP and digital systems. They increase circuit Low 4.0µA Supply Current reliability and reduce cost by eliminating external com- Precision Monitoring of 2.85V to 5.0V Power- ponents and adjustments. Supply Voltages These devices perform a single function--they assert a Reset Thresholds Available from 2.63V to 4.80V, reset signal whenever the VCC supply voltage declinesbelow a preset threshold, keeping it asserted for a preset in Approximately 100mV Increments timeout period after VCC has risen above the reset Fully Specified over Temperature threshold. The only difference among the three devices is their output. The MAX6801 (push/pull) and MAX6802 Three Power-On Reset Timeout Periods Available (open-drain) have an active-low RESET output, while the (1ms min, 20ms min, 100ms min) MAX6800 (push/pull) has an active-high RESET output. Low Cost The MAX6800/MAX6801 are guaranteed to be in the cor-rect state for V Three Available Output Structures: Push/Pull CC down to 0.7V. The MAX6802 is guaran- teed to be in the correct state for VCC down to 1.0V. RESET, Push/Pull RESET, Open-Drain RESET The reset comparator in these ICs is designed to ignore Guaranteed RESET/RESET Valid to VCC = 0.7V fast transients on VCC. Reset thresholds are factory- (MAX6800/MAX6801) trimmable between 2.63V and 4.80V, in approximately100mV increments. These devices are available with a Power-Supply Transient Immunity 1ms (min), 20ms (min), or 100ms (min) reset pulse No External Components Required width. Ideal for space-critical applications, theMAX6800/MAX6801/MAX6802 come packaged in a 3- 3-Pin SOT23 Package pin SOT23.
