600mA USB-Compatible Lithium Battery Charger
CN3062
General Description:
The CN3062 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.
Furthermore, the CN3062 is specifically designed to
work within USB power specifications. Its low
external component count makes CN3062 ideally
suited for portable applications.
Thermal feedback regulates the charge current to
limit the die temperature during high power
operation or high ambient temperature. The
regulation voltage is internally fixed at 4.2V, it can
also be adjusted with an external resistor. The charge
current can be programmed externally with a single
resistor. When the input supply (wall adapter or USB
supply) is removed, the CN3062 automatically enters
a low power sleep mode, dropping the battery drain
current to less than 3uA. Other features include
under-voltage lockout, automatic recharge, battery
temperature sensing and charging/termination
indicator.
The CN3062 is available in a thermally enhanced
8-pin SOP package.

Board Layout Considerations
1. RISET at ISET pin should be as close to CN3062 as possible, also the parasitic capacitance at ISET pin
should be kept as small as possible.
2. The capacitance at VIN pin and BAT pin should be as close to CN3062 as possible.
3. During charging, CN3062’s temperature may be high, the NTC thermistor should be placed far enough to
CN3062 so that the thermistor can reflect the battery’s temperature correctly.
4. It is very important to use a good thermal PC board layout to maximize charging current. The thermal path
for the heat generated by the IC is from the die to the copper lead frame through the package lead(especially
the ground lead) to the PC board copper, the PC board copper is the heat sink. The footprint copper pads
should be as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the
surrounding ambient. Feedthrough vias to inner or backside copper layers are also useful in improving the
overall thermal performance of the charger. Other heat sources on the board, not related to the charger,
must also be considered when designing a PC board layout because they will affect overall temperature rise
and the maximum charge current. The ability to deliver maximum charge current under all conditions
require that the exposed metal pad on the back side of the CN3062 package be soldered to the PC board
ground. Failure to make the thermal contact between the exposed pad on the backside of the package and
the copper board will result in larger thermal resistance.
