Ultra Low-Power (35nA!) Programmable Timer using TI TPL5111. Imagine a system for example that has to work from a small coin cell for 5-10 years. TPL5111 solves a typical problem in low power wireless systems- things need to be off most of the time, and wake up periodically to transmit. Ultra Low-Power (35nA!) Programmable Timer […]

The DRV8871 is a brushed-DC motor driver for printers, appliances, industrial equipment, and other small machines. Two logic inputs control the H-bridge driver, which consists of four N-channel MOSFETs that can control motors bidirectionally with up to 3.6-A peak current. The inputs can be pulse-width modulated (PWM) to control motor speed, using a choice of […]
