FAQ about PMIC - Gate Drivers
-
1. What is a gate driver?
Circuit, gate signal enhancement, controller
A gate driver is a circuit that is mainly used to enhance the gate signal of a field effect transistor (MOSFET) or an insulated gate bipolar transistor (IGBT) so that the controller can better control the operation of these semiconductor switches ，The gate driver controls the gate of the MOSFET or IGBT by converting the signal output by the controller into a high-voltage, high-current pulse, thereby improving the performance, reliability and service life of these devices.
Working principle
The gate driver is mainly composed of an input stage, a driver stage and an output stage:
Input stage: responsible for receiving the signal output by the controller and converting it into a TTL or CMOS logic level.
Driver stage: amplifies and converts the signal to generate a high-voltage, high-current pulse signal.
Output stage: uses these pulse signals to control the gate of the MOSFET or IGBT. -
2. How to choose a gate driver for a MOSFET?
When selecting a gate driver for a MOSFET, the following key factors need to be considered:
Current drive capability: The current drive capability of the gate driver directly affects the turn-on and turn-off speed of the MOSFET. Higher current sinking and sourcing capabilities mean faster turn-on and turn-off speeds, thereby reducing switching losses.
Fault detection function: The gate driver should have fault detection functions such as undervoltage lockout (UVLO), desaturation (DESAT) detection, etc. to ensure the safety and stable operation of the system.
Interference immunity: Common mode transient immunity (CMTI) is an important parameter to measure the anti-interference ability of the gate driver. In high-power systems, high CMTI values can better resist voltage transients and ensure stable operation of the system.
Electrical isolation: Electrically isolated gate drivers can achieve electrical isolation between control signals and power devices to ensure system safety. Optical coupling isolation and magnetic coupling isolation are common electrical isolation technologies, and the selection should be compared according to application requirements.
Switching frequency: For high-frequency switching applications, the switching frequency of the gate driver should match the switching frequency of the MOSFET to ensure efficient operation.
Transmission delay: Transmission delay and transmission delay matching are important parameters of electrical isolation drivers, which affect the response speed of the signal and the stability of the system. -
3. What is a motor gate driver?
A motor gate driver is a circuit that is mainly used to enhance the gate signal of a field effect transistor (MOSFET) or an insulated gate bipolar transistor (IGBT) so that the controller can better control the operation of these semiconductor switches. It converts the low-voltage signal output by the controller into a high-voltage, high-current pulse signal to ensure that the MOSFET or IGBT can switch states stably and quickly within its operating range.
