1. A controller of an electronic vaping (e-vaping) device, comprising:
control circuitry configured to cause the e-vaping device to,
generate a control signal for controlling detection of whether a cartridge section is being connected to and being disconnected from a power supply section,
receive a detection signal based on the control signal, and
detect attachment events based on the detection signal, the attachment events indicating whether the cartridge section is being attached to or being detached from the power supply section,
wherein the control circuitry includes a cartridge detection circuit including a first resistor having a first end connected to an input terminal and a second end connected to a metal-oxide-semiconductor field effect transistor (MOSFET) switch which has a gate connected to a control terminal, a second resistor having a first end connected to a ground terminal and a second end connected to the MOSFET switch and to a base of a bipolar junction transistor (BJT) switch which has a collector connected to a detection terminal.
