Highly Integrated ISL78083 Automotive Camera PMIC Provides Multiple Features and Power Density to Fit Ever-Shrinking HD Camera Modules.
'The innovative ISL78083 PMIC expands Renesas' support for automotive surround view camera systems beyond the image processing capabilities of the R-Car SoC and into the design of the HD satellite cameras,' said
The feature-rich 4-channel ISL78083 automotive camera PMIC includes a primary high-voltage synchronous buck regulator, two secondary low-voltage synchronous buck regulators, and a low-dropout (LDO) voltage regulator. With integrated feedback and integrated compensation, all that is left to complete the high efficiency power supply is the output inductor and capacitors. The ISL78083 minimizes BOM cost, requiring 7-10 less external components compared to competing solutions. The ISL78083 also features four overvoltage (OV) and four undervoltage (UV) monitors, three power-good indicators and a reset output/fault indicator. A second reference is supplied for the OV/UV monitors.
Key Features of ISL78083 Automotive Camera PMIC
Input voltage of 4V to 42V supports power-over-coax or direct from a 12V battery power source
Three buck regulators provide programmable output ranges from 1V to 5.05V, and the LDO supports 2.8V to 3.4V
2.2MHz switching frequency avoids AM band interference and shrinks the required output capacitance and inductance
An optional spread spectrum feature addresses
Wettable flank package improves reliability of solder connections and enables optical inspection of solder joints for lower cost manufacturing
AEC-Q100 Grade-1 qualified for ambient operation from -40-degreeC to +125-degreeC, and junction temperature from -40-degreeC to +150-degreeC
