The MAX25249/MAX25249B are high-efficiency, four-output PMICs that integrate three DC-DC converters and a high-PSRR LDO, with OV/UV monitoring on all outputs. OUT1 is a 1A high-voltage synchronous step-down converter operating from power over coax or car battery. OUT2 and OUT3 low-voltage synchronous step-down converters operate from OUT1 and provide a 0.8V to 3.9875V output voltage range. OUT2 can deliver 1.2A for high-megapixel cameras and high-speed serializers. OUT3 can deliver 1.2A to power the secondary rails of the imager, serializer, and MCU. OUT4 is a low-voltage, low-noise, high-PSRR LDO for imager power. All buck converters achieve ±1.5% output voltage accuracy over load, line, and temperature range. Overvoltage and undervoltage faults are monitored with ±1.3% accuracy around the set voltage, and errors are communicated through active-low RESET.The devices feature a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient response. The high-frequency operation allows for the use of all ceramic capacitors and minimizes external components. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low-RDS(ON) switches improve efficiency at heavy loads and make layout simpler than discrete solutions.Sequencing through the use of EN23 and EN4 pins and factory-settable output voltages increases flexibility for different image sensors and configurations. Other features include soft-start, overcurrent, and overtemperature protections. The MAX25249/MAX25249B are compliant with ASIL B ratings and are specified for operation over the -40°C to +125°C automotive temperature range.ApplicationsFront/Rear/Surround View Camera

The MAX20084B is a dual-antenna power supply with an I2C interface for diagnostics and control.

The MAX25606 6-switch matrix manager IC for automotive lighting applications includes a 6-switch array for bypassing individual LEDs in a single- or dual-string application. It features six individually controlled n-channel MOSFET switches with each switch having an on-resistance of 0.2Ω and rated to withstand 16V. A single current source can be used to power all the LEDs connected in series. Individual LEDs can be dimmed by turning on and off the bypass switches across each LED. The device can also be configured in two string applications with three switches in series per string. Each switch can be connected across one, two, or three LEDs in series. It also allows for parallel connection of two switches to bypass high-current LEDs. The IC also includes an internal charge pump that powers the gate drive for the switches.The IC features a universal asynchronous receiver-transmitter (UART) communication interface. Each switch can be turned on, turned off, or PWM modulated with 12 bits of PWM duty cycle adjustment. Transitions between two different PWM settings can either happen instantly or a logarithmic fade transition can be applied. The logarithmic fade algorithm is built into the device and only requires a single software command. The IC features open-LED protection as well as open and short LED fault reporting through the serial interface. The device is available in a 20-pin 4x4mm side wettable TQFN and a 20-pin thin shrink small-outline package (TSSOP) with exposed pad.
