Battery – Connect to a single cell Lithium Ion Battery.
CMP
2
Compensation – Connect a series combination of a 1k resistor and a 0.47μF capacitor from CMP to IN.
DCOK
4
Power status logic pin and LED driver – This pin is an open drain output that can sink 20mA of current to
drive an external LED. This pin is low impedance to GND when the Input voltage is high enough to charge
the Battery.
Ground – Connect to the system ground.
GND

HCP

High Current Programming (and Termination Current Programming) – Connect a resistor to ground to set the
constant current high level. The termination current is set to 1/10 of the High Current Programming Level.
For a value of 19.6k, the High Current is 460mA and the Termination Current is 46mA.
High or Low load select logic input – A logic high selects the constant charge current level set by the HCP pin
resistor and a logic low selects the constant charge current level set by the LCP pin resistor
Input Power – Connect to a wall adapter or a USB power plug.

Low Current Programming – Connect a resistor to ground to set the constant current low level.
For a value of 19.6k, the High Current is 460mA and the 20% current is 92mA.
Shutdown – A logic high places the LX2207 in sleep mode; can also be used for USB suspend.
SD

STAT
3
Charging status logic pin and LED driver – This pin can source or sink 10mA of current to drive an external
LED in either output state. This pin is low (current sinking mode) when the battery is in charging mode and
becomes high (current sourcing mode) when the charge cycle is finished. It becomes high impedance when
the input power is removed.
Battery Temperature Monitor – This sense pin determines the battery temperature for charging out of
temperature range lockout and is connected to a resistor network as defined in the Applications section. The
TMP pin is grounded if this function is not used.
20% select logic input – When the low current level is selected by the H/L pin, a logic high on 20% selects the
constant charge current level set by the LCP pin resistor and a logic low selects 20% of this value.
