General Description

The SP730 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized.

It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level.

The SP730 has an internal 5k pull-up resistor.

Key Features

  • Holds Microcontroller in Reset.
  • Reset Microcontroller during power loss.
  • 4.375 Voltage Trip Point.
  • Active Low RESET Pin.
  • Internal Pull-up Resistor.
  • Holds RESET for 350ms (typical).
  • RESET valid down to VDD1.0V.
  • 45µA Typical Operating Current.
  • Offered in a 3 Pin SOT-23 Package.
