Pinout
1. PB (Pin 1): Pushbutton Input. It detects the button press.
2. KILL (Pin 2): Input to disable the system. An external signal can be used to turn off the system.
3. GND (Pin 3): Ground. This is the reference point for the circuit.
4. ~ON~ (Pin 4): Open-drain output. It indicates that the system is on.
5. VCC (Pin 5): Supply Voltage. It powers the device, typically 2.7V to 26.4V.
6. /INT (Pin 6): Interrupt Output. It signals when the pushbutton is pressed.
7. ~RELEASE~ (Pin 7): Indicates the release of the pushbutton.
8. NC (Pin 8): No Connection. Not internally connected.
The LTC2950CTS8-1 is used in power management applications to control the on/off state of devices, providing a simple interface for user-controlled power cycling.
