1 / 5 page ACE809 3-Pin Microprocessor Reset Circuits VER 1.3 1 Description The ACE809 is a cost-effective system supervisor Integrated Circuit (IC) designed to monitor VCC in digital and mixed signal systems and provide a warning signal when the system power supply is out of working range, and a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 20μsec of VCC falling through the reset voltage threshold. Reset is maintained active after VCC rises above the reset threshold. The ACE809 has an active-low RESET output. The output of the ACE809 is guaranteed valid down to VCC=1V. The ACE809 is characterized for operation from -40℃ to 85℃, junction temperature. The ACE809 is optimized to reject fast transient glitches on the VCC line. Low supply current of 7μA (VCC=3.3V) makes these devices suitable for battery powered applications. The output voltages range from 1.7V to 4.5V in 100mV increments. Standard voltage versions are 2.30, 2.63, 2.93, 3.08, 4.0, 4.38, and 4.63V. Features Precision Vcc Monitor for 2.8V, 3.0V,3.3V and 5.0V Supplies 150ms Guaranteed Minimum RESET Output Duration RESET Output Guaranteed to Vcc=1.0V Low 7μA Supply Current. Vcc Transient Immunity. No External Components. ESD rating is 7KV(HBM) Wide operating temperature: -40℃ to 85℃ Application Embedded systems Computers Critical μP power supply monitoring Battery powered equipment Absolute Maximum Ratings (1) Parameter Symbol Max Unit Supply Voltage VCC 5.5 V Output Voltage RESET -0.3 to (Vcc+0.3) V Input Current 20 mA Output Current IOUT 20 mA Power Dissipation PD Internally Limited (3) Output short circuit duration Infinite Thermal resistance junction to ambient θ JA 230 ℃/W Operating Temperature Range TA -40~85 ℃ Operating junction temperature range TJ 0 to 125 ℃ Storage temperature range TS -60 to 150 ℃ |
