ROHM introduces 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.

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 45µA makes it ideal for battery charging via USB or adapter for mobile phones, portable audio players, IC recorders, digital cameras, and handheld gaming devices.
