Basic Load Switch A load switch is comprised of two main elements – the pass transistor and the on/off control segment. The pass transistor is most commonly a P-channel or N-channel MOSFET that passes ...

The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

By using a load switch instead of a discrete MOSFET circuit, the solution size can be reduced to 4 mm 2 or smaller. This results in a 3.5X improvement in power density.

The circuit in Fig. 1 shows a typical hot-swap or soft-switch circuit with a high-side n-channel MOSFET. This circuit is placed between an always-on power supply and a load.

Mosfet opto-relays switch more than ever Omron has announced mosfet opto-relays that can switch 3.3Aac or 6.6Adc, giving them the highest-ever current carrying capacity, said the firm. Mosfet relays ...

Toshiba launches an IPD that controls the conduction and shut-off of current supplied tor automotive electronic control units (ECUs).
