ABLIC targets power management IC for automotive cameras
ABLIC has introduced a power management IC for automotive cameras that integrates three rails and targets space-constrained ADAS camera modules. The S-19560B series combines two DC-DC converters and one LDO in a compact footprint designed for up to 16 V input systems. For eeNews Europe readers, the device potentially offers a path to reducing camera-module footprint while keeping thermal and sequencing control manageable as camera counts rise in driver-assistance and surround-view designs.
Three-channel PMIC focuses on camera-module downsizing
The S-19560B is ABLIC’s first PMIC integrating two step-down DC-DC channels and one LDO in the HSNT-8(2030) package, which measures 2.0 × 3.0 × 0.5 mm. Its 4.0 V to 16 V input range aligns with 12 V automotive camera systems and intermediate rails used with image sensors and serializers.
To build a four-rail power tree, ABLIC positions the S-19560B alongside its S-19255 high-PSRR LDO. The company states that this pairing can potentially reduce the mounting area by about 20% compared with competing four-channel PMIC solutions for 5-megapixel automotive camera modules. The proposal uses a limited external BOM: two inductors and five capacitors for the PMIC plus two capacitors for the external LDO, supporting tighter board constraints.
Thermal management and sequencing for ADAS cameras
ABLIC keeps one LDO external to spread heat and avoid concentrating thermal load within the PMIC package. Placing the external LDO near the image sensor can potentially shorten the supply path and limit noise on sensitive rails, which is often an issue in higher-resolution ADAS and surround-view cameras.
The S-19560B is supplied with preset voltages and power-up sequencing, enabling operation as a camera power-tree without firmware configuration. According to ABLIC, this is intended to ease development when managing varied voltage and startup requirements across sensor and serializer combinations.
As a power management IC for automotive cameras, the S-19560B series is also tested across low, normal and high temperature ranges, with AEC-Q100 qualification and PPAP support planned. This positions the device for adoption in mainstream automotive camera modules as designers work to balance power density with thermal headroom.
In multi-camera ADAS architectures, using a dedicated power management IC for automotive cameras may help standardise designs across platforms while keeping module size and thermal load under control — a point of interest for European suppliers working on compact, high-resolution systems.
