description
The TWL2213 is a single-chip battery and power management solution for wireless handsets, pagers, personal
data assistants (PDAs), and other battery-powered devices. For battery charging, the device incorporates a
linear charger for single-cell Li-Ion and lithium polymer battery packs. Prior to charging, the TWL2213 initiates
battery pack wake up and damaged cell detect functions. For deeply discharged batteries, the device performs
precharge conditioning by trickle-charge to user-defined current settings. Once acceptable pack voltage is
detected, TWL2213 applies a constant-current fast charge at a current level that is determined by a combination
of an external sense resistor and user-programmable sense voltage. When the battery reaches the selected
charge regulation voltage, TWL2213 maintains regulation until charging is terminated by a minimum current or
a timer. During the entire charge cycle, TWL2213 monitors temperature by external thermistor and suspends
charging if temperature exceeds a programmed range. Three programmable safety timers limit the precharge,
constant-current, and total charge times.
For power management, the TWL2213 includes six low-dropout linear voltage regulators. One regulator is
driven from the device’s power on/off logic and incorporates a microcontroller reset function. Five low noise
regulators include individually programmable output voltage and enable-disable. The TWL2213 can be
powered from a battery or AC adapter. When an adapter is present, it supplies power to the device, allowing
the system to function without battery.
TWL2213 also includes individually selectable drivers for three separate backlight LEDs, a ringer, and a vibrator
motor. An internal 8-bit analog-to-digital converter (ADC) is accessible from external pins. The system
microcontroller accesses all TWL2213 programming and status via the I2C serial interface.
The TWL2213 device is packaged in the Texas Instruments 48-terminal plastic thin quad flatpack (TQFP)
package (PFB).
