Texas Instruments TPS65222-Q1 Power Management IC (PMIC)
Texas Instruments TPS65222-Q1 Power Management IC (PMIC) device meets the power management requirements of the processors and platforms in various safety-relevant applications. This PMIC has four step-down DC/DC (BUCK) converters, of which two can be used in a dual-phase configuration. The TPS65222-Q1 PMIC also features three Low-Dropout (LDO) regulators, which can be used as load switches. This PMIC is characterized across an ambient temperature range of -40°C to 125°C, making the device an excellent choice for automotive applications. The TPS65222-Q1 devices are AEC-Q100 qualified for automotive applications. This PMIC is deal for Automotive infotainment and digital cluster, Camera Mirror System (CMS), Driver Monitoring System (DMS), Occupancy Monitoring System (OMS), and ADAS front camera.
