description
The TWL2203 incorporates a complete power-management system for a cellular telephone that uses
lithium-ion cells. The device includes circuitry to control the gate voltage of two P-channel MOSFETs. The
MOSFETs perform constant-voltage/constant-current charging (CVCC). The TWL2203 has seven low-drop
linear voltage regulators (LDO) to regulate the battery power supply to the different sections of the phone, a
battery voltage monitor, a ringer driver, an analog multiplexer, and three general-purpose operational amplifiers
for signal conditioning.
The TWL2203 is packaged in TI’s 48-pin thin-quad flat package (PFB).
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

detailed description
battery-charging control
The battery charging control block in the device is a part of the lithium-ion battery (Li-Ion) charging system of
the phone. It is capable of regulating the external power source to charge the lithium-ion battery according to
the battery-charging requirements. More information on battery-charging control is presented in the application
information section.
The MOSFET driver and its feedback-control circuit are enabled/disabled by a CMOS control signal provided
by the phone’s microprocessor. The maximum-charging current is set by external resistors for design flexibility.
overvoltage shutdown
The device shuts down the charging circuit in the presence of an overvoltage condition.
low-dropout linear voltage regulators
The device has seven separate low-dropout linear-voltage regulators. A single enable signal controls four of
the regulators. The last three regulators are controlled by their own enable signals.
voltage detectors (with power-off delay)
The device has two voltage detectors. The voltage detectors monitor the voltage level of the external power and
V
. The external power detector (VDET1) has a CMOS output. The V
detector (VDET2) activates on the
CC
CC
falling edge and has user-adjustable power-off delay. There is an internal pullup resistor on the output.
analog multiplexer
The device has a four-channel analog multiplexer with two-bit channel-selector signal input and a shutdown
function. In the shutdown mode, all the input and output terminals are in the high-impedance state.
operational amplifiers
The device has three rail-to-rail operational amplifiers with common shutdown control.
power supply switch for external phone accessories
The device provides current-limited voltage supply to the external phone accessories via the external-interface
connector. The power supply switch is controlled by the same enable signal (EN1) that controls the four
regulators—LDO1-LDO4. The external phone accessories are resistive in nature.
ringer driver
The device is capable of driving a ringer. It is controlled by a CMOS signal, and uses an N-channel low-side
driver.

THERMAL INFORMATION
The implementation of integrated circuits in low-profile and fine-pitch surface-mount packages requires special
attention to power dissipation. Many system-dependent issues such as thermal coupling, airflow, added heat
sinks and convection surfaces, and the presence of other heat-generating components affect the power-
dissipation limits of a given component.
Three basic approaches for enhancing thermal performance are listed below.
Improving the power dissipation capability of the printed-circuit board design
Improving the thermal coupling of the component to the printed-circuit board
Introducing airflow into the system
Using the given R
for this device, the maximum power dissipation can be calculated with the equation:

APPLICATION INFORMATION
capacitor selection
The output bypass capacitor of each LDO regulator should be selected from the list of ceramic capacitors shown
below. The VCC bypass capacitors should be selected from the list of tantalum capacitors shown below.
Tantalum capacitors have good temperature stability and offer good capacitance for their size. Care should be
taken when using marginal quality tantalum capacitors, as the increase of the equivalent series resistance
(ESR) at low temperatures can cause instability. For a given capacitance, ceramic capacitors are usually larger
and more costly than tantalums. The capacitance of ceramic capacitors varies greatly with temperature. In
addition, the ESR of ceramic capacitors can be low enough to cause instability. A low-value resistor can be
added in series with the ceramic capacitor to provide a minimum ESR.

APPLICATION INFORMATION
battery-charging control (continued)
The battery-charging control block in the device is a part of the Li-Ion battery charging system of the phone. The
device controls the P-channel MOSFET to accomplish constant-voltage/constant-current charging (CVCC)
within a ±1% tolerance in the charging termination voltage.
The battery charging control consists of the two sections:
CVCC charge-switch control with feedback loops for voltage and current control
Trickle charge-current control
When the voltage-detector output (DET1) is set high, the voltage-control loop is activated to regulate the voltage
of ICH- to 4.2 V. Then, when the control signal input CH is set high, either the current-control loop or the
trickle-charge control block is activated, depending upon battery voltage.
When VB is below the threshold Vtc, the trickle-charge current control block directs the current to the battery
viaTCIN, trickle-chargingcurrentcontrol, TCOUT, R6, andthebattery. Themeasureofthevoltageacrosssense
resistor R6 is used for feedback-control of the rate of charging current.
Once the battery voltage reaches the threshold Vtc, the CVCC charge-switch control block becomes active and
controls the P-channel MOSFET M1. The feedback control ensures that the voltage ICH- does not exceed 4.2
V ± 0.05 V (4.2 V regulation), and the current draw of resistor R1 does not exceed the specified value
(current-limit control). In this case, the charging current drains via R1, M2, and the battery. The maximum
charging current is set by external resistors for design flexibility.
