• Specifically tailored to the AMD Elan SC500 Series

• /RESET remains valid with VCC as low as 1V

• 5µA typical supply current

• 1100ms minimum reset pulse width

• Manual reset input

• Available in 4-Pin SOT-143 Package

Applications

• Portable equipment

• Intelligent instruments

• Critical microprocessor power monitoring

• Printers/computers

• Embedded controllers
