Maxim Integrated MAX16151 High Voltage Pushbutton On/Off Controller
https://www.electronics-lab.com/maxim-integrated-max16151-high-voltage-pushbutton-on-off-controller/
Maxim Integrated MAX16151 High Voltage Pushbutton On/Off Controller, featuring a switch debouncer and a latched output, is optimized for controlling system power. The MAX16151 can accept a noisy input from a mechanical switch and produce a clean, latched output. The device can also produce a one-shot interrupt output, in response to a switch closure exceeding the debounce period […]
Current Limit Solid State Power Switch with Latch
https://www.electronics-lab.com/current-limit-solid-state-power-switch-latch/
The project published here is a solid state power switch with current limiting that prevents damage to host devices from faulty load conditions. This analog current limit switch have low on-resistance P-channel MOSFET and INA202 driver IC from Texas instrument. The project operate from input voltage in the range 5V to 24V and can handle […]

Graham Prophet @ eedesignnewseurope.com discuss about Melexis magnetic latch and switch sensors. He writes: Melexis (Tessenderlo, Belgium) has introduced a range of new magnetic latch and switch sensors that feature two silicon dice in the same package, yielding highly reliable devices, which are aimed at automotive applications including transmission, power steering, braking and locks/latches. Dual die, […]
Soft Latch Power Switch Circuit
https://www.electronics-lab.com/soft-latch-power-switch-circuit/
Dаvid Jones through his Youtube channel EEVblog described in detail how to design a cheap soft latch power switch circuit, using one push button switch to toggle your circuit power on and off with the following design requirements: Zero power when off. One on/off switch. Standalone(no MCU). General components only (Diodes, Transistors, ..ect). Minimal parts. […]
