for portable devices provides up to 28V of over voltage protection
for charger ICs. Built-in circuits include overvoltage lockout,
overcurrent limit, undervoltage protection, internal start up delay,
and status flag.
● Features
1) 28V (max) overvoltage protection
2) Low quiescent current (45µA)
3) Low Ron (125mΩ) FET
4) Overvoltage lockout (OVLO) circuit
5) Undervoltage lockout (UVLO) circuit
6) Internal 2msec start up delay
7) Overcurrent protection circuit
8) Compact package: VCSP50L1 (1.6mm x 1.6mm, t=0.55mm)
● Applications
Mobile phones, MP3 players, digital cameras
VCSP50L1
● Absolute Maximum Ratings (Ta=25°C)

BD6047AGUL可防止整机因来自USB端子的超标输入电压而损坏。除以往的充电保护IC的功能外，还可在不增加外置部件的前提下对因USB的反接等而发生的负电压进行保护。通过采用罗姆自有的本系列技术，实现了针对最大±30V的异常输入电压的保护。
