SP810规格书详情
描述 Description
The SP810 is a low power microprocessor (μP) supervisory circuit used to monitor power supplies in μP and digital systems.
It provides 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 SP810 has been designed with a reset comparator to help identify invalid signals, which last less than 140ms. The SP810 has an active-high RESET output.
特性 Features
• Ultra-low supply current 1µA (typ.)
• Guaranteed reset valid to VCC = 0.9V
• 140 ms minimum power-on reset pulse width
• Internally fixed threshold 2.6V
• Tight voltage threshold tolerance: 1.5%
• Offered in a 3-pin SOT-23 package
应用 Application
• Portable electronic devices
• Electrical power meters
• Digital still cameras
• uP power monitoring
