The UC3543N from Texas Instruments is a versatile power supply supervisory circuit integrated circuit. It is designed to monitor and control power supply systems, offering features such as over-voltage and under-voltage sensing.
Key electrical specifications include a wide supply voltage range of 4.5V to 40V, a nominal output voltage of 2.5V, and a maximum power dissipation of 1W. The device operates within a temperature range of 0°C to 70°C. It features programmable time delays and an internal 1% accurate reference.
This IC is housed in a 16-DIP (0.300", 7.62mm) package and is mounted through hole. The UC3543N is suitable for general power management applications where reliable monitoring and control of power supply rails are critical. It includes open collector outputs that can be used independently or wire-ORed together.
Additional features include an optional over-voltage latch and remote activation capability. The device also incorporates an uncommitted comparator for low voltage sensing. The SCR crowbar drive capability provides a shutdown mechanism.
