NXP Semiconductors PCA9452 Single Chip Power Management ICs
NXP Semiconductors PCA9452 Single Chip Power Management ICs are designed to support i.MX 93x family processors in both automotive and extended industrial applications. These PMICs offer highly efficient six step-down regulators, five Low Dropout voltage (LDOs), one 400mA load switch, a 2-channel level translator, and a 32.768KHz crystal oscillator driver. Three buck regulators support Dynamic Voltage Scaling (DVS) features along with programmable ramping up and down time. The LDO1 features a very low quiescent current to provide power for Secure Non-Volatile Storage (SNVS). The PCA9452 PMICs operate at -40°C to 105°C ambient temperature range and integrate a 2-bit logic translator dual supply translating transceiver with auto direction sensing. Typical applications include Driver Monitoring Systems (DVS), occupant monitoring systems, cost-optimized gateway, and automotive infotainment (Audio and speech recognition).
