MAX41464, MAX38888 andMAX16141 demonstrate leading advances in efficiency, size and versatility for next-generation electronic systems

Designers striving for greater efficiency and performance from increasingly compact electronic systems will be able to tap into three newbuilding-blockanalog ICsfrom Maxim Integrated Products, Inc. (NASDAQ: MXIM). TheMAX41464 sub-1GHz wireless transmitter, the MAX38888backup power regulator, and the MAX1614136-volt ORingFET controller for building automation, industrial, automotive, and portable applications will be featured atthe electronica 2018conference, Nov. 13-16, in Messe Munchen, Germany.

System designersare constantly looking for ways to improve system efficiency and performance, extend battery life, add new features and reduce form factor and bill-of-material (BOM) costs. Maxim’s newest analogICsdemonstrate the industry-leading capabilities that pave the way for them to achieve these outcomes.

Industry’s Highest Output Power, Sub-GHz FSK Transmitter

MAX41464 is a sub-1GHz frequency-shift keying (FSK) transmitter with the industry’s highest output power of+16dBm for long-range wireless sensors used in multiple applications including building automation and security systems. Operating from a single coin-cell battery, the transmitter extends battery life by consuming only 12mAoperating current, 30 percent lower than that of the closest competitor. The transmitter is fully programmable using an I²C interface. A preset frequency mode optionusing a single 16MHz crystal eliminates programmingand allows a single wire interface to an external microcontroller. In preset mode, the part also features auto-shutdown at less than 20nA shutdown current as well as data activity detector for auto-wake. Itsfrequency-hopping range from 300MHz to 960MHz supports worldwide use and the IC can be used in extreme temperature conditions with a minus 40-degree Celsius to 105-degree Celsius ambient temperature range.

Enable Backup, Uninterruptable Power forMission-Critical Applications

Maxim’s Continua™ family ofbackuppower regulatorsis setting the standard for backup power in mission-critical applications.  The high-performance regulators charge a backup power source, such as a supercapacitor or capacitor bank, in just seconds to deliver continuous power to critical system components when the main power source is turned off. The MAX38888 reversible buck/boost regulator, the first member of the Continua family, delivers an industry-leading 95 percent peak efficiency. Operating over 2.5 to 5V input in buck mode, the MAX38888 charges an energy storage device at up to 500mA peak inductor current. On supply failure, MAX38888operates in a boost mode, providing 2.5 to 5V output at up to 2.5Apeak inductor current from an energy storage device, discharging all the way to 0.8V. In portable electronics where the main power source is a battery, the MAX38888 doublesbattery lifeby lowering quiescent current up to 15 times lower than competitive solutions during idle mode. MAX38888 is available in a 38mm² solution size, which is 33 percent smaller than the closest competitive solution.

Ensure Automotive Electrical System Protection

MAX16141 is a 36V ORing FET controller with voltage and current circuit breakerfor monitoring over-voltage, under-voltage, over-current, reverse-current and over-temperature conditions in automotive power applications, including infotainment and advanced driver assistance systems (ADAS). Providing a full suite of system protection functions, the controller elicits a rapid response time of 0.3µs to reverse current events, increasing system hold-up time and functionality during automotive transient conditions. By enabling a true shutdown mode to prevent leakage current and by minimizing the current draw to inactive circuitry, the controller decreases total system power and prioritizes engine starting powerover all other electrical systems.
