TPS65216 Power Management IC (PMIC)

Texas Instruments TPS65216 Power Management IC (PMIC) is a single-chip IC specifically designed to provide power management for all the functionalities of the AMIC110 and AMIC120 processors. The DC/DC converters DCDC1 through DCDC4 are intended to power the core, MPU, DDR memory, and 3.3V analog and I/O, respectively. LDO1 provides the 1.8V analog and I/O for the processor. GPIO2 allows for a warm reset of the DCDC1 and DCDC2 converters. The I²C interface allows the user to enable and disable all voltage regulators, the load switch, and GPIOs. Additionally, UVLO and supervisor voltage thresholds, power-up sequence, and power-down sequence can be programmed through I²C. Interrupts for overtemperature, overcurrent, and undervoltage can be monitored as well. The supervisor monitors DCDC1 through DCDC4 and LDO1. The supervisor has two settings, one for typical undervoltage tolerance (STRICT = 0b) and one for tight undervoltage and overvoltage tolerances (STRICT = 1b). A power-good signal indicates the proper regulation of the five voltage regulators.
