FEATURES
1
2The purpose of the TPS659110 device is to
provide the following resources:
• Embedded power controller (EPC) with
EEPROM programmability
• Two efficient step-down DCDC converters for
processor cores (VDD1, VDD2)
• One efficient step-down DCDC converter for
I/O power (VIO)
• One controller for external FETs (VDDCtrl)
• Dynamic voltage scaling for processor cores
• Eight LDO voltage regulators and one RTC
LDO (supply for internal RTC)
• One high-speed I²C interface for general-
purpose control commands (CTL-I²C)
• Two independent enable signals for
controlling power resources (EN1, EN2).
Alternatively, these pins can be used as a
high-speed I²C interface dedicated for voltage
scaling for VDD1 and VDD2.
• Thermal shutdown protection and hot-die
detection
• A real-time clock (RTC) resource with:
– Oscillator for 32.768-kHz crystal or 32-kHz
built-in RC oscillator
– Date, time and calendar
– Alarm capability
• Nine configurable GPIOs with multiplexed
feature support:
– Four can be used as enable for external
resources, included into power up
sequence and controlled by state-machine.
– As GPI, GPIOs support logic-level detection
and can generate maskable interrupt for
wake-up.
– Two of the GPIOs have 10 mA current sink
capability for driving LEDs.
– DCDCs switching synchronization through
an external 3-MHz clock.
• Two reset inputs, for cold reset (HDRST) and a
power initialization reset (PWRDN) for thermal
reset input
• 32-kHz clock and reset (NRESPWRON) for
system and an additional output for reset
signal
• Watchdog
• Two ON/OFF LED pulse generators and one
PWM generator
• Two comparators for system control,
connected to VCCS pin
• A JTAG^® and boundary scan, but not
accessible in functional mode (test purpose)
APPLICATIONS
• Portable and handheld systems
DESCRIPTION
The TPS659110 is an integrated Power Management
IC available in 98-pin 0.65-mm pitch BGA package
and dedicated to applications powered by one Li-Ion
or Li-Ion polymer battery cell or 3-series Ni-MH cells
or a 5 V input, and which require multiple power rails.
The device provides three step-down converters, one
controller for external FETs to support high current
rail, eight LDOs, and is designed to be flexible PMIC
for supporting different processors and applications.
Two of the step-down converters provide power for
dual processor cores and support dynamic voltage
scaling by a dedicated I²C interface for optimum
power savings. The third converter provides power for
the I/Os and memory in the system.
The device includes eight general-purpose LDOs
providing a wide range of voltage and current
capabilities. Five of the LDOs support 1.0 to 3.3 V
with 100-mV step and three (LDO1, LDO2, LDO4)
support 1.0 to 3.3 V with 50-mV step. All LDOs are
fully controllable by the I²C interface.
In addition to the power resources, the device
contains an EPC to manage the power sequencing
requirements of systems and an RTC. Power
sequencing is programmable by EEPROM.
Figure 1 shows the top-level diagram of the device.
