电源管理和USB单芯片 Power Management and USB Single Chip
The TPS65921 device is a highly integrated power-management circuit IC that supports the power and peripheral requirements of the OMAP application processors. The device contains power management, a universal serial bus USB high-speed HS transceiver, an analog-to-digital converter ADC, a real-time clock RTC, a keypad interface, and an embedded power control EPC. The power portion of the device contains three buck converters, two controllable by a dedicated SmartReflex class-3 interface, multiple low-dropout LDO regulators, an EPC to manage the power-sequencing requirements of OMAP, and an RTC module. The USB module provides an HS 2.0 transceiver suitable for direct connection to the OMAP universal transceiver macrocell interface UTMI + low pin interface ULPI with an integrated charge pump CP.
The device also provides auxiliary modules: ADC, keypad interface, and general-purpose inputs/outputs GPIOs muxed with the JTAG functions. The keypad interface implements a built-in scanning algorithm to decode hardware-based key presses and to reduce software use, with multiple additional GPIOs that can be used as interrupts when they are configured as inputs.
