General Description:
The CN3162 is a complete constant-current /constant
voltage linear charger for single cell lithium
rechargeable battery. The device contains an on-chip
power MOSFET and eliminates the need for the
external current sense resistor and blocking diode. Its
low external component count makes CN3162
ideally suited for portable applications.
