Features, Applications

Microprocessor Supervisory Circuit with Pull Up Resistor

FEATURES Holds Microcontroller in 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 VDD1.0V 45μA Typical Operating Current Offered a 3 Pin SOT-23 Package APPLICATIONS Portable Electronic Devices Electrical Power Meter Computer System Board Modem


DESCRIPTION The 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 voltage. The part is available in a small 3 pin SOT-23 package. Contact factory for other trip voltage options. TYPICAL APPLICATION CIRCUIT


VDD................................................................................................. 6.0V All inputs and outputs w.r.t. GND............................... -0.6 to VDD+ 1.0V Storage Temperature.................................................. to +150°C Ambient Temperature with power to +125°C ESD Protection on all pins............................................................ 2kV These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.
