The voltage detector is an IC chip that monitor the voltage of power supply line to output a detected signal when the voltage falls below or exceeds the setting voltage,which is also shorted for VD.Siproin provides low-power low-voltage detection chips, which are available in two forms: CMOS output and NMOS open-drain output.
STT-MRAM (Spin Transfer Torque Magnetic Random Access Memory) is the second generation of MRAM (magnetic random access memory). Its core advantage lies in the use of spin current technology to achieve efficient information writing. The core component of its storage unit is a finely designed MTJ (magnetic tunnel junction), which consists of two ferromagnetic layers of different thicknesses sandwiched by a non-magnetic isolation layer that is only a few nanometers thick. This unique design makes STT-MRAM an advanced non-volatile memory that performs data writing operations by precisely controlling the spin current.
Smart meters include new prepaid meters, multi-rate meters, and electronic meters with two-way communication capabilities, which provide extended functions including automatic meter reading (AMR), online query, remote connection/disconnection, and complex billing structures etc.
SSP1839 is a built-in clock calibration-free energy measurement chip, suitable for single-phase multi-function energy meters, smart sockets, smart home appliances, electric bicycle charging piles and other applications, and has a high cost performance.
During electronic design, we always need different DC voltages to provide circuit work. The most commonly used one is to use LDO voltage regulator chips to achieve the output of different DC voltages. So how to choose a suitable LDO is particularly important. Many engineers during selecting progress, they only select based on the two indicators of output voltage and current, but ignoring several other key technical indicators, resulting in the selected LDO is not the best choice. Let's learn about the working principle of LDO and several important technical indicators.
