MAX809中文资料Voltage Supervisor, Very Low Supply Current, 3-Pin Microprocessor, Reset Monitor数据手册ONSEMI规格书

描述 Description

The MAX809/NCV809 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 µsec of VCC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trimmed by factory after VCC rises above the reset threshold. The MAX810 has an active-high RESET output while the MAX809 has an active-low RESETbar output. Both devices are available in a SOT-23 and SC-70 packages. The MAX809/810 are optimized to reject fast transient glitches on The VCCline. Low supply current of 0.5 µA (VCC = 3.3 V) makes these devices suitable for battery powered applications.
