2.3.2 Advanced Power Management Features

The TPS65214 incorporates a sophisticated system management architecture that enhances both reliability and flexibility. The programmable power sequencing controller allows complete customization of start-up and shutdown sequences with eight configurable time slots and durations ranging from 0ms to 10ms. This precise control provides proper initialization of complex systems and prevents problems associated with improper power sequencing.

The comprehensive protection system of the device continuously monitors for undervoltage, overcurrent, and short-circuit conditions across all power rails. Thermal protection with multiple threshold levels prevents damage during extreme operating conditions. When potential issues are detected, the configurable fault response system can either trigger immediate shutdown, notify the host processor, or take pre-programmed corrective actions.

System designers benefit from a flexible I2C interface that provides complete control over all power parameters. The interface supports standard, fast, and fast-plus modes, enabling integration with virtually any host processor. Dynamic voltage scaling allows real-time adjustment of output voltages during operation, enabling sophisticated power optimization strategies that significantly extend battery life in portable applications.

Multifunction pins provide additional flexibility, allowing the PMIC to be configured for various system architectures. These include configurable GPIO pins that can sequence external power devices, push button input for system control, and reset outputs or interrupt outputs for processor coordination.

The non-volatile memory configuration of the TPS65214 makes sure that system parameters are preserved across power cycles, while the ability to program custom settings provides flexibility for diverse application requirements. This combination of advanced features and robust design makes the power system of the BeagleBone Green Eco exceptionally capable, reliable, and efficient across a wide range of operating conditions.
