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
DD
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.
