O917A131TRGZRQ1 Information

TPS65917/TPS65917-Q1 Power Management IC (PMIC)

Texas Instruments TPS65917/TPS65917-Q1 Power Management IC (PMIC) integrates five configurable step-down converters with up to 3.5A of output current to power the processor core, memory, I/O, and preregulation of LDOs. The step-down converters are synchronized to an internal 2.2MHz clock to improve EMC performance of the device. The GPIO_3 pin allows the step-down converters to synchronize to an external clock, allowing multiple devices to synchronize to the same clock. This feature improves system-level EMC performance. The device also contains five LDOs to power low-current or low-noise domains. The power-sequence controller uses one-time programmable (OTP) memory to control the power sequences. This memory also controls default configurations such as output voltage and GPIO configurations. The OTP is factory-programmed to allow start-up without any software required. Most static settings can be changed from the default through SPI or I2C to configure the device to meet many different system needs. The TPS65917-Q1 devices are AEC-Q100 qualified for automotive applications.
