KTF809 Microprocessor Management Unit   datasheet sales@icdidik.com


Overview
The KTF809/810 Microprocessor Reset Circuits are low-power supervisory devices used to monitor power supplies. They perform a single function: asserting a reset signal whenever the VCC supply voltage drops below a preset value and keeping it asserted until VCC has risen above the preset threshold for a minimum period of time.
 
Features
  • Precision monitoring of 3V, 3.3V, and 5V supply voltages
  • Minimum 140ms reset pulse width
    • KTF809 - active-low output RSTB
    • KTF810 - active-high output RST
  • Low supply current – 7uA typical
  • Guaranteed RESET assertion down to VCC=1.0V
 
Applications
  • Computers
  • Controllers
  • Battery-powered instrument
  • Microprocessor systems
