The DW03C from Shenzhen Slkormicro is a single-cell battery protection IC for lithium-ion and lithium-polymer batteries. It integrates over-current, over-temperature, over-voltage, and short-circuit protection in a compact SC-74A (SOT-753) package. Operating from -40°C to 85°C, it is suitable for consumer electronics, wearables, and portable devices. Its small size and comprehensive safety features make it a versatile choice for 1S battery packs.

  • All-in-One Protection: Combines over-current, over-temperature, over-voltage, and short-circuit protection in one IC.
  • Ultra-Compact Package: SC-74A (SOT-753) fits space-constrained PCB designs in wearables and earbuds.
  • Wide Temperature Range: -40°C to 85°C covers consumer and outdoor portable devices.
  • Chemistry Flexibility: Supports both lithium-ion and lithium-polymer cells.

Smartphone and Tablet Batteries

Single-cell lithium-polymer packs in mobile devices use the DW03C for comprehensive protection against overcharge, over-discharge, and short circuits.

Wearable Devices

Smartwatches and fitness trackers with small 1S lithium-polymer cells benefit from the compact SOT-753 package and low power consumption.

Portable Bluetooth Speakers

Rechargeable speakers with single-cell lithium-ion batteries rely on this IC for over-temperature and over-current safety during high-volume playback.

E-Cigarettes and Vaping Devices
