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 switched-
mode 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.
