1.3 Description

The TWL6032 device is an integrated power-management integrated circuit (PMIC) for applications

powered by a rechargeable battery. The device provides five configurable step-down converters with a

current capability of up to 5.0 A 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 and power-down controller is configurable and can support any

power-up or 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 TWL6032 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 switchedmode

regulator 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; in this case, the battery is always tied to the system

supply and the switched-mode regulator is used for battery charging.

The TWL6032 device is available in a 155-pin WCSP package, 5.21 mm × 5.36 mm with a 0.4-mm ball

pitch.
