detailed description (continued)
LED driver
The TWL2213 device provides the capability of driving three LEDs. These drivers, enabled by I2C, can drive
currents of 160 mA, 20 mA, and 10 mA individually with a maximum voltage drop of 0.8 V.
ringer driver
The TWL2213 device provides the capability of driving a ringer. It is enabled by I2C and uses an N-channel FET
with a maximum resistance of 3
.
I2C
This block provides I2C interface to the external devices.
battery charger control
This block provides the necessary signals to control the external circuits that perform the charger function. The
charging activities include battery pack wake up, precharge, fast charge, and battery temperature monitoring.
This block also provides two ADC inputs for general measurement purpose. The input voltage level is from 0
to 2 volts. This block also includes an oscillator generator circuit, which generates the clocks for the device. The
nominal frequency of the main clock is 500 kHz. It requires an external capacitor of 470 pF.
reference system
This block provides voltage reference and bias current for the internal circuitry.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
