Low noise, compact, low dropout (LDO) voltage regulators from Toshiba Electronics Europe are suitable for use in a variety of portable and wearable devices, such as sensors, RF devices and IoT applications or any applications where the available board space is at a premium and high-density mounting is required.
ICs & Semiconductors
Li+ fuel gauge and IC monitors and protects battery life
Maxim Integrated claims to offer the industry’s first Li+ fuel gauge IC which has continuous internal self-discharge monitoring and protection. The MAX17320 series cell Li-ion fuel gauge IC extends run-time on multi-cell battery-powered products while also monitoring against self-discharge hazards. The pack-side fuel gauge and protector IC is for two to four series Lithium-ion (Li+) cells (2S-4S). It is part of a family of ICs equipped with Maxim Integrated’s patented ModelGauge m5 EZ algorithm that delivers 40 per cent more accurate state of charge (SOC) readings than competitive offerings, eliminating the need for battery characterisation for most common Li+ cells, claims the company. This fuel gauge is also claimed to offer the industry’s lowest quiescent current (IQ), which is 85 per cent lower than the nearest competitor and features SHA-256 authentication to safeguard systems from counterfeit batteries.
Maxim MAX77655 is smallest SIMO PMIC yet
Claimed to provide the highest number of output channels and to reduce overall product size by 70 per cent, the MAX77655 single-inductor multiple output (SIMO) power management IC (PMIC) from Maxim Integrated targets portable wearables, IoT sensor nodes and health monitors.
STMicroelectronics collaborates with Qualcomm for next-gen sensors
Combining the iNEMO LSM6DST six-axis inertial measurement unit (IMU) with what is believed to be the industry’s first I3C-enabled pressure sensor, the LPS22HH, STMicroelectronics and Qualcomm Technologies claim to provide highly accurate location tracking while meeting the most restrictive power budgets.
