Description

The TPS80032 device is an integrated power-management integrated circuit (PMIC) for applications

5.0-A current capability for memory, processor core, I/O, auxiliary, preregulation for LDOs, and so forth.

The device also contains nine LDO regulators for external use that can be supplied from a battery or a

preregulated supply. The power-up/power-down controller is configurable and can support any power-

up/power-down sequence (programmed in OTP memory). The RTC provides three 32-kHz clock outputs:

seconds, minutes, hours, day, month, and year information; as well as alarm wakeup and timer. The

TPS80032 device supports 32-kHz clock generation based on a crystal oscillator.

The device integrates a switched-mode system supply regulator from a USB connector. The device

includes power paths from the USB and battery with supplemental mode for immediate startup, even with

an empty battery. The battery switch uses an external low-ohmic PMOS transistor allowing minimal serial

resistance during fast charging and when operating from battery. The device can also be used without the

external PMOS transistor; the battery is then always tied to the system supply and the switched-mode

regulator is used for battery charging.

The TPS80032 device is available in a 155-pin WCSP package, 5.21 mm × 5.36 mm with a 0.4-mm ball

pitch.
