DESCRIPTION
The WM8325-00C is an integrated power-management
subsystem which provides a cost-effective, flexible, single-chip
solution for power management. It is specifically targeted at
the requirements of the Freescale i.MX53 multimedia
applications processor.
The start-up behaviour and configuration is optimised for
compatibility with the Freescale i.MX53 processor, and is
stored in an integrated OTP non-volatile memory.
The WM8325-00C is a pre-programmed variant of the
WM8325, pre-configured for the Freescale i.MX53 processor.
Note that the WM8325 supports user-programming of the
integrated OTP memory, providing full flexibility in configuring
the device for a wide range of application and mobile
processors for low-power consumer multimedia applications.
The WM8325-00C power management subsystem comprises
four programmable DC-DC converters and eleven LDO
regulators (four of which are low-noise for supplying sensitive
analogue subsystems). The integrated OTP bootstrap circuitry
controls the start-up sequencing and voltages of the converters
and regulators as well as the sequencing of system clocks.
The DC-DC converters deliver high performance and high
efficiency across a wide range of operating conditions. They
are optimised to support the high load current transients seen
in modern processor core domains. DC-DC3 / DC-DC4 are
configured in ¡®dual¡¯ mode to support an increased current load
of up to 1.6A.
An on-chip regulator provides power for always-on PMIC
functions such as register map and the RTC. The device
provides autonomous backup battery switchover. A low-power
LDO is included to support ¡®Alive¡¯ processor power domains
external to the WM8325-00C.
