Product Description
The CM3403 is a micropower low voltage supply supervisor designed to provide the necessary power-on reset control for microprocessors and memory applications. An internal pull-down resistor on the RESET output ensures the output remains valid under all supply conditions.

FEATUREs
• Precision voltage sensor
• Two threshold options: 2.93V or 4.63V
• Stable over temperature
• Valid output logic while VCC = 0V.
• Power-on reset pulse width of 140ms (min.) to 460ms (max.)
• Low quiescent current (40µA typ.)
• No external components required
• 3-pin SOT23 package
• "809" compatible pinout
• Lead-free versions available

APPLICATIONs
• Critical µP and µC power monitoring
• PCI applications
• Memory integrity during "brownouts"
