The L6470 is a fully integrated motor driver. It provides a complete standalone solution for stepper motor applications. The L6470 is controlled by a host microcontroller (MCU) through a fast 8-bit serial peripheral interface (SPI). Multiple L6470 drivers can be…
High-side current sensing is used in a wide range of applications. Usually, it is used for overcurrent protection in power management circuits. On the market, there are many off-the-shelf operational amplifiers that can be used to measure current on the…
The high-speed photodiode circuit in Figure 1 uses a low capacitance PIN photodiode (PD), load resistance (RL), and a high-speed operational amplifier (U). In this configuration, the photodiode is reverse biased and used in photoconductive mode. The short circuit current…
