Semtech HotSwitch Protection ICs

Mouser Electronics, Inc. now stocks the HotSwitch protection ICs from Semtech Corporation. The HotSwitch platform includes integrated load switches and eFuses with an elevated protection feature set designed to protect electronics systems against typical electrical transients and steady-state fault conditions.

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

HotSwitch devices are designed to detect electrical surges and provide security to the downstream subsystem by disconnecting the load from the power source. The devices offer a 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 an 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 x 3 mm 12-pin DFN package. The device offers thermal shutdown functionality and faults flagging to defend 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 x 2 mm 14-pin DFN package.

Both HotSwitch devices provide 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.
