Description
Gate driver circuit is a power amplifier that takes low power signal as input from other circuit or IC and then in response to that signal produces a high power signal that is used to drive the gate of high power transistor or any other device that requires high power signal as input. A half bridge gate driver is a circuit that is used to drive the low side and high side gate of the MOSFET with low output impedance, fast switching and reduced switching loss. Half bridge gate driver circuits can drive only two gates.
FAN7380MX is a half bridge gate driver circuit. A gate driver IC acts as an interface between the control signal and power switches. A gate driver IC reduces the complexity of the circuit while improving the efficiency of the system. FAN7380 is a monolithic half bridge gate driver IC for driving the gate of high power MOSFETs and IGBTs. The IC is so designed that it can handle bootstrapping voltages up to 600V. Output produced by the device are in phase with the input signal which is also compatible with TTL input logic thresholds.
Pin Description
IC is available in eight pin small outline package (8-SOP)
IC Electrical Characteristics/ Specifications
FAN7380 is available with lead free terminal and can be mounted on printed circuit boards, some electrical characteristics of the IC are given below
Working Principle
Half bridge gate driver circuit’s function is to drive the gates of high and low side MOSFETs. High and low side driver need very close matching of timing characteristics to allow accurate and efficient switching. This reduces the down time/ dead time from one switch of the half bridge turning OFF before the second switch turns ON.
Applications
Half bridge gate driver circuits are used in wide range of applications including the followings
● Fluorescent lamp ballast
● Compact fluorescent lamp ballast
● Solar inverters
● DC-DC power supply
Fluorescent Lamp Ballast
Ballast circuits are used in electronics to limit the amount of current to the load. A very common example of use of ballast is in fluorescent lamp. IC FAN7380MX will drive the load by turning ON and OFF the switching devices which are MOSFET in this case and hence will control the amount of current through the load.
Power Factor Corrected Power Supply
Power factor correction is a technique used to improve the power factor the power supplies. Switching power supplies without power factor correction will draw current in the form of high magnitude pulses. Since the FAN7380MX switches at very high speed switching losses are reduced to minimum. A power factor corrected power supply using FAN7380MX is shown below
