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

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

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.
