Nanopower Analog ICs Enable Sub-1V, Micropower Current Sensing Techniques

Current-sense amplifiers can monitor battery or solar cell currents, and are useful to estimate power capacity and remaining life. However, if the battery or solar source is a single cell, it's difficult to find a low voltage solution that works below 1V and draws just microamps. A new class of nanopower analog ICs, namely Touchstone Semiconductor's TS1001 0.8V/0.6µA op amp, makes a sub-1V supply current sense amplifier possible. With its extremely low power, the circuit can simply remain "always on", providing a continuously monitored, averaged indication of current which can be read by a microcontroller without too much current drain.

This month, Trinamic Motion Control is offering you to win one of four TMCM-1043 development kits for its highly integrated, NEMA 17-compatible TMCM-1043 stepDancer stepper motor module.
Offering designers an easy-to-use PC-based GUI that allows one-click modification of motor drive current, micro-stepping and other key parameters, the intuitive kits are custom designed and developed for direct mounting on a NEMA 17 motor. Pre-programmed and pre-configured with all operating parameters to support standard 1.5A (peak) motors, the TMCM-1043 board uses Trinamic´s single-axis TMC2660 stepper motor driver IC, which integrates a motor pre-driver and power MOSFETs.
