Charge Protection IC for Mobile USB Devices

The Industry’s Smallest High-Performance Charge Protection IC for Mobile USB Devices

ROHM has recently developed the most compact high-performance USB charge protection IC to protect battery driven (i.e. nickel hydride, lithium ion) devices from damage due to excessive current or voltage surges during USB charging.

BD6040GUL - Charge Protection IC | click to enlarge picture!

The BD6040GUL features improved safety design and integrates high performance protection circuits (i.e. low 125mΩ ON-resistance FET switch, 28V overvoltage lockout, undervoltage lockout, overcurrent protection, startup delay, and temperature protection) into a 1.6 x 1.6mm2 ultra-compact CSP (chip scale package) that reduces mounting area by 30% over conventional products. A market-leading current consumption of 45ľA makes it ideal for battery charging via USB or adapter for mobile phones, portable audio players, IC recorders, digital cameras, and handheld gaming devices.
