The APX803L-46SA-7 is a Supervisory Circuits 4.6V, 0ms Reset Generator manufactured by Diodes Incorporated. It is an integrated circuit (IC) that provides voltage monitoring and reset generation in systems with +4.6V logic supply or +3.3V logic supply. It includes a low voltage detector which is set, with external resistors, to detect power supply failure conditions. Additionally, it contains a fixed width reset pulse generator that can be used to reset the system when the monitored voltage drops out of tolerance. Its features include low voltage detect voltages, reset pulse width, external resistor programming, low power consumption, manual reset, and under voltage lockout.
