TPS65912 Power Management ICs (PMICs)

Texas Instruments TPS65912 Power Management ICs (PMICs) provide four configurable step-down converters with up to 2.5A output current for memory, processor core, I/O, or pre-regulation of LDOs. These devices also contain ten LDO regulators for external use. These LDOs can be supplied from either a battery or a pre-regulated supply. The power-up or power-down controller is configurable and can support any power-up or power-down sequences (OTP-based). The TPS65912 integrates a 32kHz RC oscillator to sequence all resources during power-up or power-down. All LDOs and DC-DC converters can be controlled by the I²C-SPI interface or basic ENABLE balls. In addition, an independent automatic voltage-scaling interface allows for the transition of DC-DC to a different voltage using I²C or basic roof/floor control. Three RGB LEDs, with an advanced dimming feature, are integrated into the device. GPIO functionality is multiplexed with LED/ENABLE/SPI when not used. Each GPIO can be configured as part of the power-up sequence to control external resources. One SLEEP pin enables power mode control between the active mode and preprogrammed sleep mode for power optimization. For system control, the TPS65912 device has one comparator for system state management.
