The LTC2954CTS8-1#TRPBF is an integrated circuit (IC) for supervisory circuits pushbutton on/off controllers with U interrupt interfaces for menu-driven applications. Manufactured by Analog Devices, it operates from a single 1.8V to 5.5V power supply. It includes a programmable time delay to allow up to a 90 second timeout before a system’s power is shut off. This IC is capable of detecting power up/down events, under voltage, and overvoltage (OVP) conditions. It also features a power fail flag, timer enable/disable flag, and manual reset (MR) flag. In addition, the IC incorporates an on/off push-button switch with a debouncing circuitry, overvoltage lockout (OVLO), and an optional crystal oscillator for providing accurate timeout time periods. Additionally, it includes a self-start up option which allows users to either manually start the system or to wait for a push-button press to start the system. The LTC2954CTS8-1#TRPBF is an optimal part for menu-driven applications that require a push button on/off controller.
