Quad Channel PMIC for Automotive Camera Modules
5 November 2025 Nisshinbo Micro Devices, a leader in innovative semiconductors has announced the launch of the NP8700 series, a quad-channel Power Management IC (PMIC) designed to meet the stringent power, size, and noise requirements of next-generation automotive camera modules. The new PMIC integrates four independent regulators in a compact QFN2634-26-NC package, enabling cameras to be installed in tight spaces such as headliners, mirrors, and centre consoles while simplifying the bill of materials and PCB-layout.
The company says the device is specifically engineered for image-quality-sensitive systems, the NP8700 combines a high-voltage 1.2 A synchronous buck converter for primary conversion, a second 1.0 A synchronous buck converter, a flexible third channel that can be configured either as a 1.0 A synchronous buck converter or as a 0.2 A low-noise LDO, plus a fourth channel with a 0.2 A LDO that may also be used as a high-side switch when required.
Anti-phase operation between the primary and secondary converters and an optional spread-spectrum frequency modulation mode help suppress conducted and radiated emissions, stabilising sensor performance and overall camera reliability. A built-in power-good output with externally programmable delay time with a single capacitor allows designers to eliminate an additional reset IC, while a simple resistor-programmed power-on sequence supports orderly startup and controlled shutdown across rails.
The device operates at a fixed 2.0 MHz switching frequency with optional external clock synchronisation. It also and offers various safety circuits, such as hiccup / foldback or latched over-current protection, soft-start on all channels, built-in phase compensation, and a UVLO with two selectable threshold options.
The NP8700 supports a wide input range, with the primary converter operating from 3.9 V to 20 V and the low-voltage rails from 2.4 V to 5.5 V, addressing typical automotive power domains. The product is qualified to AEC-Q100 Grade 1 and is specified for −40 °C to 125 °C ambient operation, meeting the reliability expectations of in-vehicle deployments.
