情境
A dual door control system where capacitive touch sensors provide momentary operation for safety. Upon releasing the touch, motors stop and doors spring close.

看懂背後的決策。
01
Use of low-side N-channel MOSFET switches for simplicity
02
Momentary touch sensors with pull-down resistors ensure motors are off when not touched
03
Freewheeling diodes protect against inductive kickback
Applicable to automatic door systems requiring fail-safe momentary touch control, such as hospital or cleanroom doors.
