Battery time in always-on wearable and IoT devices can be extended, says Maxim Integrated Products, with the integrated MAX20345 power management IC (PMIC). It integrates a lithium charger and uses an architecture that optimises the sensitivity of optical measurements for wearable fitness and health applications, says the company.

ams shrinks distance measurement and proximity sensing sensor
Claimed to be the world’s smallest 1D time of flight sensor (ToF), the TMF8701 has been introduced by ams.
Nanopower PMICs extend battery life for IoT applications
Two integrated nanopower PMICs for IoT applications, the DA9070 and DA9073, have been released by Dialog. The PMICs are designed for ‘always-on’ IoT devices such as fitness trackers, smartwatches and smart home products which are expected to spend less time tethered to a charger, while expanding feature sets present new challenges to battery life.
LDO extends portable devices’ battery life
Prolonging battery life by up to four times longer than traditional low quiescent (Iq) LDOs, the MCP1811 is a linear low dropout (LDO) regulator available from Microchip. It enables reduced standby power consumption in remote, battery-powered sensor nodes and also enables faster response times and transient response for IoT, wearable and remote designs, says Microchip.
