Gate Drivers for Power MOSFETs and IGBTs - Microchip Technology
A gate driver is a type of power amplifier that accepts a low-power input from a controller IC and produces a high-current drive input for the gate of a high-power transistor such as an Insulated-Gate Bipolar Transistor (IGBT) or power MOSFET. Gate drivers are beneficial to MOSFET operation because the high-current drive provided to the MOSFET ...
Fan Controller ICs - Microchip Technology
Fan controller ICs are devices that integrate Pulse-Width Modulation (PWM) controllers with temperature sensors, ramp rate control, spin-up algorithms and look-up tables for setting the fan speed (PWM duty cycle) according to the measured temperature and ramp rate control. These devices are a great fit if you have limited software resources but ...
