Cross Reference

Handheld and Consumer

Compact, low-IQ ICs for wearables, earbuds, action cameras, and portable electronics

Battery life in handheld products is dominated by quiescent current and idle-state losses. Magnias's portfolio is built around ultra-low-IQ LDOs (sub-µA class), load switches with sub-µA shutdown current, and small-package MOSFETs (DFN1006 to SOT-23) that fit the tight PCB area in earbuds, wearables, and pocket-sized IoT devices. Combined with our ESD arrays for USB-C and audio jack protection, customers can build a complete signal-path and power BOM for consumer-grade products.

Application areas

TWS earbuds (charge case + earpiece)

  • Ultra-low-IQ LDO (sub-1 µA shutdown)
  • Load switch (audio / BLE power gating)
  • ESD on USB-C charge port
  • Photodiode bias LDO (proximity sensor)

Wearable (smartwatch / fitness band)

  • Tiny-package LDO (DFN1010 / X2SON)
  • Logic-level MOSFET (sensor power gating)
  • ESD on display flex cable
  • Voltage supervisor (POR / wake)

Action camera / drone

  • Buck converter (sub-1V image-sensor core)
  • 60V MOSFET (motor / gimbal)
  • TVS on USB-C / HDMI port
  • Open-drain INT for sensor alerts

IoT sensor node

  • Sub-µA LDO (always-on rail)
  • Load switch (radio gating)
  • ESD on antenna + battery contacts
  • Comparator (window-detect / wake)
