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