By employing the MAX14720 power management integrated circuit (PMIC), from Maxim Integrated Products, designers can optimize power and battery life for wearable medical / fitness and Internet of Things (IoT) applications.
Increasing battery life and achieving low power are common challenges faced by engineers when developing wearable and IoT products. The MAX14720 PMIC is ideal for non-rechargeable battery (coin cell, dual alkaline) applications where size and energy efficiency are critical. In addition, an electronic battery seal extends shelf life by effectively disconnecting the battery prior to initial power-up. Integrating the functionality of five discrete devices - power switch, linear regulator, buck regulator, buck-boost regulator, and monitor - the MAX14720 reduces the bill of materials (BOM) and allows for much smaller form factor designs, says the company.
“In 2020, 190 million wearable electronic devices for fitness and health will be sold, generating $14.4 billion in revenue1,” according to Gartner. Angela McIntyre, research director and Michele Reitz, principal research analyst, Gartner, said, “system design for wearables will remain fairly straightforward, employing basic microcontroller unit (MCU)-based processing, BT and Wi-Fi communications, and accelerometer and gyro sensor chips, with display drivers, optoelectronics, USB charging interfaces, small NOR memory and power regulator chips playing major roles in many wearable designs.”
