Protection ICs prolong electronic device life span

The HotSwitch platform includes integrated load switches and eFuses with a first-of-a-kind elevated protection feature set optimised for protecting electronics systems against typical electrical transients and steady-state fault conditions.

Electronic waste, or e-waste, is the fastest-growing source of waste globally, with e-waste volumes growing to 53.6 million metric tons in 2019, an increase of 21% since 2014, according to the Environmental Protection Agency.

Semtech's HotSwitch platform, which aids in safeguarding electric systems, provides elevated protection features that prolong the life span of electronic devices and potentially reduce e-waste.

The HotSwitch devices are specifically designed to detect electrical surges and provide robust security to the downstream subsystem by gracefully disconnecting the load from the power source.

They offer an enhanced shield against inrush current, overvoltage, under voltage, reverse current, short circuit and over-temperature faults.

The HS2950P HotSwitch is a single-channel integrated high-side load switch with a wide input voltage range of 2.7 V to 29 V, which supports up to 5 A output current. The HS2950P comes in a small 3 mm x 3 mm 12-pin DFN package. The device offers thermal shutdown functionality and faults flagging to ensure a rugged defence for downstream industrial, telecom and consumer systems subject to transients and short circuits risk.

The HS2240P HotSwitch is an integrated eFuse and surge protection device designed to protect against various electrical overstress (EOS) conditions, including lightning, electrostatic discharge (ESD) and short circuits. The device works in an input voltage range of 2.7 V to 22 V, with a current limiting threshold of 3.9 A. The HS2240P is housed in a small 3.5 mm x 2 mm 14-pin DFN package.

Both HotSwitch devices provide robust protection for consumer products, industrial equipment, appliances, smart TVs, and more.

These devices also enable longer battery life for portable devices due to low leakage and a low quiescent current.

The HotSwitch ICs also offer a lower bill of materials (BOM) count and a smaller footprint than discrete or multi-chip solutions.
