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. With consumers now owning up to 22 connected devices, the potential amount of e-waste has become an ongoing challenge for electronic systems manufacturers. 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.

“Semtech has a long-established reputation as a trusted and leading innovator and provider of circuit protection,” said Tamir Reshef, vice president of marketing for Semtech's Protection Products Group. “With the new HotSwitch platform, Semtech has expanded the protection tools available to the design community for safeguarding systems, prolonging operational life and enabling use of electronic systems in a more environmentally sustainable manner.”

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.

Two HotSwitch platform products are available now and can be purchased through Semtech’s distribution channels.

• HS2950P, a single channel integrated high-side load switch
  With a wide input voltage range of 2.7V to 29V, supporting up to 5A output current, this product features a low 25mΩ (typical) Rds(on) to minimize power loss and contains various adjustable protection features, including soft-start, turn on-delay, overvoltage, under-voltage, and current limit. HS2950P comes in a small 3x3mm 12-pin DFN package. The device offers thermal shutdown functionality and faults flagging to ensure a rugged defense for downstream industrial, telecom and consumer systems subject to transients and short circuits risk.

• HS2240P, an integrated eFuse and surge protection device
  Designed to protect against various electrical overstress (EOS) conditions including lightning, electrostatic discharge (ESD), short circuits and inrush current capabilities, this device works in an input voltage range of 2.7V to 22V, with a current limiting threshold of 3.9A. It incorporates a high ESD withstand voltage of ±30kV for air and contact per IEC 61000-4-2. The VIN pin of this device is rated for a high-energy transient current up to 40A (tp =8/20μs). HS2240P comes in a small 3.5x2mm 14-pin DFN package.

Universal Features of Semtech’s HotSwitch Platform

• Integrated protection circuitry that can replace conventional fuses and other protection devices.
• Delivery of higher system reliability with safety features like overcurrent, voltage, temperature and reverse current blocking.
• Enhanced system dynamic behaviors, including limited inrush current, proper loading sequence, handling minor disturbances in a system power line, and injecting lesser interference among loads.
• Longer battery life for systems with low leakage and quiescent currents.
• Lower bill of materials (BOM) count and smaller printed circuit board (PCB) area than discrete or multi-chip solutions.
• Ability to embed IEC 61000-4-2 level compliant ESD protection for some applications.
