® SP730 Microprocessor Supervisory Circuit with Pull Up Resistor 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 APPLICATIONS ■ Portable Electronic Devices ■ Electrical Power Meter ■ Computer System Board ■ Modem GND SP730 3 Pin SOT-23 RESET VDD Now Available in Lead Free Packaging 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.
The device has an active low RESET pin and will assert the RESET signal whenever the voltage on the VDD pin is below the trip-point ...
