KTF809 - Microprocessor Reset Circuit

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 hreshold for a minimum period of time.

Features:

• Generate clean and correct pulse for user-initiated (external) RESET
• Low cost precision threshold voltage detection

Applications:

• Automotive : Car MCU, Remote Keyless Entry (RKE)
• Consumer electronics : GSM phone, PDA, portable MP3 player, digital camera
• Health : Glucose meter, blood pressure monitor
• Others : RFID, GPS device, alarm systems
  

Typical Applications for KTF809:

Communication products such as Modem, Router, Network Switch, VOIP phone, Videophone.     Consumer electronics products such as GSM phone, PDA, portable MP3 player, digital camera.       Health products such as Glucose meter, blood pressure monitor.       Others products such RFID, GPS device, alarm systems.
