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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
