Halo Microelectronics, a maker of analog and power management integrated circuits enabling energy-efficient smart systems announced that its HL5501, a wireless smart power load switch IC is protecting Samsung’s Galaxy S22 Ultra flagship smartphones in Korean and Canadian models.
The Halo Microelectronics HL5501 is a high-voltage protection load switch IC allowing up to 30V. The input/output pins can stand off from ±40V at the off condition to protect the smartphone against positive and negative coil pin voltage faults. In addition, the HL5501 provides a well-optimized solution for wireless charging Tx/Rx in the mobile application.
In a recent Insight Analytical Labs’ Galaxy S22 Ultra teardown report, the Halo Microelectronics’ HL5501 (JCM9) Wireless RX Coil Switch was present on the main board, as it supports Samsung’s phone-to-phone or phone-to-watch charging through the wireless coil. Depending on the charging device, they control the coil size through the HL5501, which is optimized for power transfer and minimizes unnecessary radiation.
Samsung Galaxy S22 Ultra uses Qualcomm SM8450 Snapdragon 8 Octa-Core processor and boasts a 6.8-inch edge quad HD+ dynamic AMOLED 2x display with 16% more brightness. The 120Hz adaptive refresh rate keeps the scroll smooth and adjusts to what’s on-screen for an optimized view. Its battery is 5000mAh (typical) and with 45W super-fast charging that can provide battery life from dusk until dawn on one charge, according to the Samsung website. The Galaxy S22 Ultra is also the first Galaxy S smartphone that comes with a built-in S pen. The iconic S Pen fits right into S for the first time and can be used to take notes, edit content, and draw sketches with precision.
“Samsung Galaxy S22 Ultra smartphone users will appreciate the leading-edge technology, its innovation, and performance,” said David Nam, CEO of Halo Microelectronics. “Samsung and Halo Microelectronics are aligned in providing the next generation of high-performance and reliable smartphones while ensuring quality and sustainability,” he added.
