SP809EK-L-2-9/TR
监控电路 3 PIN MICROPROCESSOR RESET CIRCUIT 3 Pin Microprocessor Supervisor Circuit
GENERAL DESCRIPTION
The SP809EK-L-2-9/TR SP809/SP810 are low power microprocessor (μP) supervisory circuits used to monitor power supplies in μP and digital systems.
They provide applications with benefits of circuit reliability and low cost by eliminating external components. If the VCC supply voltage falls below preset threshold then a reset signal is asserted for at least 140ms after VCC has risen above the reset threshold.
The devices are available in 3 pin SOT-23 package.
APPLICATIONS SP809EK-L-2-9/TR
• Portable Electronic Devices
