TWL92230C 描述
The TWL92230 is an energy management device optimized to be a companion device for the OMAP24xx application processor. It contains power supplies and reference voltage for OMAP24xx (VCORE, VIO, VADAC, VPLL, and a 0.5-V reference), for associated memory (VMEM), for two independently powered memory cards (VMCS1 and VMCS2) and also for an extra device or auxiliary peripheral (VAUX). It contains all relevant interface signals to OMAP24xx, that allow monitoring, operation control, and changing of regulator voltage settings via the I2C serial interface. The TWL92230 also has memory card transceivers to adapt a 1.8-V processor I/O voltage to the memory card voltages. It supports two slots for MMC, SDIO, SD, or Memory Stick cards.
TWL92230C 特性
- An 880-mA buck dc-dc converter for processor core (VOUT = 1.00 V to 1.45 V).
- Two 400-mA buck dc-dc converters (VOUT = 1.5 V to 3.2 V). One dc-dc converter can be used as a preregulator for the VIO and the VMEM LDO regulators. The other dc-dc converter can power a high-current Memory Card slot.
- The dc-dc converters run at 1.2 MHz, provided by an internal clock or the clock generator/divider that accepts 12 MHz, 13 MHz, or 19.2 MHz as the high-frequency clock input.
- One 200-mA LDO regulators (VOUT = 1.50 V, 1.80 V, 1.90 V, or 2.50 V). It typically powers memory.
- One 200-mA LDO regulator (VOUT = 1.85 V, 2.80 V, 3.00 V, or 3.10 V). It typically powers a Memory Card slot, MMC/SD slot 1 (high-current level compliant with MMC/SD and SDIO 1.0).
- Two 200-mA LDO regulator (VOUT = 1.50 V, 1.80 V, 2.50 V, or 2.80 V). They typically power an extra device (flash memory, SDRAM, peripheral, etc) and the processor I/O.
- One 10-mA, high-PSRR, low-noise LDO regulator (1.30 V). It typically powers the processor PLL.
- One 2-mA, high-PSRR, low-noise LDO regulator (1.80 V). It typically powers the processor TV-Out DAC.
- One 0.5-V voltage reference that typically powers the processor TV-Out DAC.
- Backup battery switch provides the input voltage for the low-current VDIG LDO regulator. The output of this LDO is externally available for connection to a filter capacitor, but it must not be loaded externally.
- Allows dynamic voltage management for the processor core voltage.
- 32-kHz oscillator and integrated real-time clock (RTC). An external crystal or a digital 32-kHz clock signal is required.
- 400 kHz I2C compatible serial interface.
- Three general-purpose I/O ports (GPIOs). Some GPIOs may have alternative functions.
- Dual slot memory card transceivers that can be powered independently.
- Monitoring and detection circuits: thermal shutdown, hot die, low-battery, and undervoltage lockout.
- Housed in a 5mm × 5mm package (80ZQE) that is RoHS compliant and lead-free soldering process compatible.
- Typical applications: Cellular phones, smartphones, and PDAs
