NXP Semiconductors PCA9452
PCA9452 Power management IC for i.MX 93x auto processor
The PCA9452 is a single chip AEC Q100 grade 2 automotive power management IC (PMIC) specifically designed to support i.MX 93x family processors in both automotive and extended industrial applications.
Key features
- 400 mA load switch with a built-in active discharge resistor
- 32.768 kHz crystal oscillator driver and buffer output
- Six high-efficiency step down regulators
- Five linear regulators
Additional features
- The device provides six high efficiency step-down regulators, five LDOs, one 400 mA load switch, two-channel level translator and 32.768 kHz crystal oscillator driver.
- Three buck regulators support dynamic voltage scaling (DVS) along with programmable ramping up and down time.
- The buck regulators support remote sense to compensate IR drop to load from the buck regulator, allowing better performance to meet the demand for accuracy in critical supply rails.
- This device is characterized across -40 °C to 105 °C ambient temperature range and qualified by AEC Q100 Grade 2 for automotive applications.
