Integrated Power Management IC (PMIC) w/ 4 DC/DCs, 9 LDOs and RTC - TPS65911

TPS65911 (ACTIVE)

Integrated Power Management IC (PMIC) w/ 4 DC/DCs, 9 LDOs and RTC

 

Description

The TPS65911x device is an integrated power management IC (PMIC) available in a 98-pin 0.65-mm pitch BGA package. The TPS65911x device is dedicated to applications powered by one Li-Ion or Li-Ion polymer battery cell, 3-series Ni-MH cells, or a 5-V input, and applications that require multiple power rails. The device provides three step-down converters, one controller for external FETs to support high current rail, eight LDOs, and the device is designed to be a 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 that provide a wide range of voltage and current capabilities. Five of the LDOs support 1.0 to 3.3 V with a 100-mV step and three (LDO1, LDO2, LDO4) support 1.0 to 3.3 V with a 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.

Features

    The Purpose of the TPS65911x Device is to Provide the Following Resources:

  • Embedded Power Controller (EPC) With EEPROM
    Programmability
  • Two Efficient Step-Down DC-DC Converters for
    Processor Cores (VDD1, VDD2)
  • One Efficient Step-Down DC-DC Converter for I/O
    Power (VIO)
  • One Controller for External FETs (VDDCtrl)
  • Dynamic Voltage Scaling (DVS) 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, the EN1 and EN2 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 in Power-Up Sequence
      and Controlled by State Machine
    • As GPI, GPIOs Support Logic-Level Detection
      and can Generate Maskable Interrupt for
      Wakeup
    • Two of the GPIOs Have 10-mA Current Sink
      Capability for Driving LEDs
    • DC-DC Converters Switching Synchronization
      Through an External 3-MHz Clock
  • Two Reset Inputs:
    • Cold Reset (HDRST)
    • 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 and OFF LED Pulse Generators and One
    PWM Generator
  • Two Comparators for System Control, Connected
    to VCCS Pin
  • A JTAG and Boundary Scan (Not Accessible in
    Functional Mode [Test Purpose])
