SP730 - Microprocessor Supervisory Circuit

Download the SP730 datasheet PDF. This datasheet also covers the SP7 variant, as both devices belong to the same microprocessor supervisory circuit family and are provided as variant models within a single manufacturer datasheet.

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.

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.
