The MAX20086–MAX20089 dual/quad camera power protector ICs deliver up to 600mA load current to each of their four output channels. Each output is individually protected from short-to-battery, short-to-ground, and overcurrent conditions. The ICs operate from a 3V to 5.5V supply and with a 3V to 15V camera supply. The input-to-output voltage drop is only 110mV (typ) at 300mA. The ICs provide an enable input and I2C interface to read the diagnostic status of the device. An on-board ADC enables reading of the current through each switch. The ASIL B- and ASIL D-compliant versions include support for reading an additional seven diagnostic measurements through the ADC, ensuring high-fault coverage. The MAX20086–MAX20089 include overtemperature shutdown and overcurrent limiting on each output channel separately. All devices are designed to operate from -40°C to +125°C ambient temperature.

The MAX25231 is a small, synchronous automotive buck converter with integrated high-side and low-side switches. The MAX25231 is designed to deliver up to 1.2A, with 3.5V to 36V input voltages, while using only 3.5μA quiescent current at no load. The device provides an accurate output voltage of ±2% within the normal operation input range of 6V to 18V. With 65ns minimum on-time capability, the converter is capable of large input-to-output conversion ratios. Voltage quality can be monitored by observing the PGOOD signal. The device can operate in dropout by running at 99% duty cycle, making it ideal for automotive and industrial applications. The device offers two fixed output voltages of 5V and 3.3V. Frequency is internally fixed at 2.1MHz, which allows for small external components and reduced output ripple, and guarantees no AM interference. The device automatically enters skip mode at light loads with ultra-low quiescent current of 3.5μA at no load. The device offers pin-enabled spread-spectrum frequency modulation designed to minimize EMI-radiated emissions due to the modulation frequency.The MAX25231 is available in a small (3mm x 3mm) 12-pin TDFN package with an exposed pad, and uses very few external components.ApplicationsAlways-On, Low-Quiescent-Current SystemsAutomotiveHigh-Voltage DC-DC ConvertersIndustrial

MAX20019/MAX20020 are 2.2MHz and 3.2MHz dual step-down converters with integrated high-side and low-side MOSFETs. The high-voltage step-down converter is designed for continuous operation up to 17V input voltages. The output voltage is factory preset. Buck 1 is preset to 3.3V, 3.0V, or 2.8V. Buck 2 is preset to 1.8V, 1.5V, 1.2V, or 1V. Another option is Buck 1 preset to 5V and Buck 2 preset to 3.3V. The low-voltage buck features fixed-frequency PWM- mode operation with a switching frequency of 2.2MHz or 3.2MHz. High-frequency operation allows for an all-ceramic capacitor design and small-size external components. The low-resistance on-chip switches ensure high efficiency while minimizing critical inductance. A 500mV enable hysteresis on the MAX20019 allows the use of long, low-cost coax cables, even during slow startup situations. The MAX20020’s Buck 1 starts after VSUP is greater than 5.5V and Buck 1 is driven by the EN input. Protection features include overvoltage (OV) protection, cycle-by-cycle current limit, and thermal shutdown with automatic recovery. The buck converters operate 180° out-of-phase from each other to minimize input-current ripple.
