BD604x Series

USB charge protection ICs specifically designed to protect devices from damage

Image of ROHM Semiconductor's BD604x Series - USB Battery Charge Protection ICROHM’s BD604x series of high performance USB charge protection ICs were specifically designed to protect battery driven devices from damage due to excessive current/voltage surges during charging via USB or third-party AC adapters. Multiple protection circuits, including over-/under-voltage lockout, overcurrent protection, thermal shutdown, and startup delay, are integrated into the industry’s smallest package. Additional features include a low ON-resistance (125 mΩ) FET and ultra-low 45 uA current consumption, making it ideal for portable devices of all types, such as mobile phones, IC recorders, digital cameras, handheld gaming equipment, and portable audio players.

Product Features:
  • 30 V overvoltage protection circuit built in
  • Integrated low ON-resistance FET
  • Built-in OVLO (Over Voltage Lock Out) circuit
  • Equipped with a UVLO (Under Voltage Lock Out) circuit
  • OCP (Over Current Protection) circuit incorporated
  • Built-in startup delay function
  • Ultra-compact CSP package
  • Low current consumption
