The TPS659110 is an integrated Power Management Alternatively, these pins can be used as a IC available in 98-pin 0.65-mm pitch BGA package high-speed I2C interface dedicated for voltage and dedicated to applications powered by one Li-Ion scaling for VDD1 and VDD2. or Li-Ion polymer battery cell or 3-series Ni-MH cells or a 5 V input, and which require multiple power rails. • Thermal shutdown protection and hot-die The device provides three step-down converters, one detection controller for external FETs to support high current • A real-time clock (RTC) resource with: rail, eight LDOs, and is designed to be flexible PMIC – Oscillator for 32.768-kHz crystal or 32-kHz for supporting different processors and applications. built-in RC oscillator Two of the step-down converters provide power for – Date, time and calendar dual processor cores and support dynamic voltage – Alarm capability scaling by a dedicated I2C interface for optimum power savings. The third converter provides power for • Nine configurable GPIOs with multiplexed the I/Os and memory in the system. feature support: The device includes eight general-purpose LDOs – Four can be used as enable for external providing a wide range of voltage and current resources, included into power up capabilities. Five of the LDOs support 1.0 to 3.3 V sequence and controlled by state-machine. with 100-mV step and three (LDO1, LDO2, LDO4) – As GPI, GPIOs support logic-level detection support 1.0 to 3.3 V with 50-mV step. All LDOs are and can generate maskable interrupt for fully controllable by the I2C interface. wake-up. In addition to the power resources, the device – Two of the GPIOs have 10 mA current sink contains an EPC to manage the power sequencing capability for driving LEDs. requirements of systems and an RTC. Power – DCDCs switching synchronization through sequencing is programmable by EEPROM. an external 3-MHz clock. Figure 1 shows the top-level diagram of the device. • Two reset inputs, for cold reset (HDRST) and a 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 JTAG is a registered trademark of JTAG Technologies, Inc.
