LTC4091 is a complete lithium-ion battery backup management system for 3.45V to 4.45V supply rails that must be kept active during a long duration main power failure. The LTC4091 employs a 36V monolithic buck converter with adaptive output control to provide power to a system load and enable high efficiency battery charging from the buck […]

BME680 BME680 is an integrated environmental sensor developed specifically for mobile applications and wearables where size and low power consumption are key requirements. Expanding Bosch Sensortec’s existing family of environmental sensors, the BME680 integrates for the first time high-linearity and high-accuracy gas, pressure, humidity and temperature sensors. It consists of an 8-pin metal-lid 3.0 x […]

Intel’s first product was not a processor, but a memory chip: the 31011 RAM chip, released in April 1969. This chip held just 64 bits of data (equivalent to 8 letters or 16 digits) and had the steep price tag of $99.50.2 The chip’s capacity was way too small to replace core memory, the dominant storage technology […]

The need for larger memory storage for smartphones will never stop, especially with the continuous development of larger and stronger applications. This need is always pushing semiconductor manufacturers to keep trying to fit as much bits as possible in  smaller volumes and with lower costs. To achieve this, memory chips are now growing in three […]

Libre Space Foundation completed the mission of building a completely Open-Source 2U CubeSat Satellite from scratch. It’s called “UPSat”. On April 18th at Cape Canaveral in Florida, Atlas V Rocket launched Private Cygnus Cargo Ship, and UPSat was among its cargo. With both software and hardware parts published on github. UPSat seems to be a real open […]

Introducing the Digitool One of the most useful tools for micro-controller design is the logic analyzer. You can find one for every budget or performance, but lately those based in USB connection to PC have gained popularity  (not not mention the chinese copies). The main drawback of USB based logic analyzer is the need of […]

LT8609S is a 2A (3A Peak), 42V input synchronous step-down switching regulator.The synchronous step-down Silent Switcher 2 Delivers 93% efficiency at 2 MHz with ultralow EMI/EMC emissions The architecture uses two internal input capacitors as well as internal BST and INTVCC capacitors to minimize the area of the ‘hot loops’. The LT8609S design reduces EMI/EMC […]

Introducing its latest-generation Bluetooth Low Energy (BLE) System-on-Chip, ST Microelectronics hghlights low power, small size, and high performance to enable widespread deployment of energy-conscious, space-constrained applications with BLE connectivity. The device provides state-of-the-art security and is Bluetooth 5.0-certified ST uses an ARM Cortex-M0 core to provide low-power, extremely efficient, 32-bit processing performance for BlueNRG-2. Other […]

LTC3636 and LTC3636-1 are high efficiency, 4 MHz synchronous dual output buck regulators that incorporate a constant frequency/controlled on-time, current mode control scheme with phase lockable switching frequency. Their design architecture reduces conducted and radiated emissions. The devices can deliver up to 6A of continuous output current from each channel or generate a 2-phase single […]
