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 5kΩ pull-up resistor. The device has an active low RESET pin and will assert

the RESET signal whenever the voltage on the V

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.
