FAQ
What is the maximum ambient temperature rating for the S912ZVCA19F0MKH?
The S912ZVCA19F0MKH is qualified to AEC-Q100 Grade 0 with a specified ambient operating range of -40°C to +125°C. Its junction temperature capability extends to +150°C, enabling reliable deployment in under-hood or near-engine locations where thermal stress is significant. This rating is validated per JEDEC JESD47 and automotive stress test standards.
Does the S912ZVCA19F0MKH include an integrated CAN transceiver?
Yes, the S912ZVCA19F0MKH integrates a fully compliant ISO 11898-2/3 CAN physical layer (PHY) with internal termination and biasing. This eliminates the need for an external CAN transceiver, reducing bill-of-materials cost and PCB footprint. The CANH and CANL pins connect directly to the CAN bus, and configuration is handled via the MSCAN module registers.
What power supply voltages does the S912ZVCA19F0MKH support?
The S912ZVCA19F0MKH operates directly from a 5.5 V–18 V battery supply. It includes an integrated 12 V voltage regulator delivering 70 mA continuously (or 170 mA in pulsed ballast mode) to power external sensors or actuators. Core logic runs from a separate 5 V domain supplied internally or externally.
How many high-voltage input pins does the S912ZVCA19F0MKH have?
The S912ZVCA19F0MKH features two dedicated high-voltage input (HVI) pins - HVI0 and HVI1 - each rated for direct connection to 0–18 V signals. These pins support robust switch sensing, battery voltage monitoring, or wake-up detection without external level-shifting circuitry, simplifying design in automotive body control modules.
What package type is used for the S912ZVCA19F0MKH?
The S912ZVCA19F0MKH is packaged in a 64-pin LQFP with exposed thermal pad (64-LQFP-EP), measuring 10 mm × 10 mm with 0.5 mm pitch. The exposed pad enhances thermal performance in high-power automotive applications and must be soldered to a thermal plane per NXP's recommended layout guidelines.
