For building automation and automotive backup power
MAX41464, MAX38888, MAX16141
Unveiling Leading Technologies for Next-Generation Electronic Systems
Maxim Integrated has introduced three building block analog ICs that improve the efficiency and performance of electronic systems.

Maxim will showcase the MAX41464 sub-1GHz wireless transmitter for building automation, industrial, automotive, and portable applications, the MAX38888 standby power regulator, and the MAX16141 36V ORing FET controller at the 2018 electronica 2018, held at Messe München, Germany, from the 13th to the 16th (local time).


MAX41464, sub-1GHz FSK transmitter
The MAX41464 is a sub-1GHz FSK transmitter with 16dBm output power for a variety of long-range wireless sensor applications, including building automation and security systems. Operating from a single coin-cell battery, the MAX41464 extends battery life with 12mA operating current, 30% lower than competing devices, and is programmable using an I2C interface.

The preset frequency mode, utilizing a single 16MHz crystal, requires no programming and operates with a single-wire interface to an external microcontroller (MCU). The MAX41464 transmitter features a data activity detector for automatic wake-up in preset mode, as well as an automatic shutdown function with a shutdown current of less than 20nA. Its frequency range of 300MHz to 960MHz ensures worldwide operation and operates in extreme temperatures ranging from -40°C to 105°C.


The MAX38888 provides redundant uninterruptible power for mission-critical applications.
Maxim's Continua family of standby power regulators sets the standard for redundant power for mission-critical applications. High-performance Continua regulators charge backup power sources, such as supercapacitors or capacitor banks, in seconds, ensuring continuous power supply to critical system components when the main power supply fails.

The first member of the Continua family, the MAX38888 reversible buck/boost regulator, delivers 95% peak efficiency. It operates from a 2.5V to 5V input range in buck mode and charges energy storage devices with up to 500mA of peak inductor current. In case of power failure, it operates in boost mode, providing a 2.5 to 5 V output range with a peak inductor current of up to 2.5 A from the energy storage device, discharging to 0.8 V.

The MAX38888 extends battery life in battery-powered portable electronics by reducing standby current by up to 15x compared to competing solutions. Measuring 38mm2, it is 33% smaller than the competition.


MAX16141, Automotive Electrical System Protection
The MAX16141 is a 36V ORing FET controller with integrated power and voltage circuit breakers that monitors for overvoltage, undervoltage, overcurrent, reverse current, and overtemperature conditions in automotive power applications such as infotainment and ADAS. Providing system protection, the MAX16141 responds to reverse current with a 0.3µs response time, improving system hold-up time and functionality during automotive transients. It reduces overall system power by implementing a shutdown mode that prevents leakage current and minimizes current consumption for inactive circuits, prioritizing engine starting power over all other electrical systems.

“Designers are looking for devices that support innovative features in next-generation systems,” said Kevin Anderson, senior analyst at IHS Markit. “Improving system efficiency and reducing solution size are key, and Maxim’s latest analog ICs help designers create competitive products.”

“Maxim is committed to empowering our customers to continuously innovate with high-performance, general-purpose analog ICs,” said Vickram Vathulya, vice president, Core Products Group at Maxim Integrated. “From ultra-low power to extended battery life, precision signal conversion, and robust connectivity, we provide the technology and convenience that allows designers to take their products to the next level.”
