ROHM BD6040GUL

Charger Protection IC with Internal FET
BD6040GUL
● Outline
●Dimensions (Unit:mm)
The BD6040GUL charger protection IC developed
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)
