MOSFET overcurrent protection circuit to avoid power supply burnout accidents
Power supply as electronic equipment distribution components, in addition to the characteristics to consider the provisions of the power supply system equipment, its own protective measures are also very important, such as over-current, over-voltage, over-temperature mai...Read more -
How to select the most suitable driver circuit for MOSFET?
In the power switch and other power supply system design program, program designers will pay more attention to a number of major parameters of the MOSFET, such as on-off resistor, larger operating voltage, larger power flow. Although this element is critical, taking into...Read more -
MOSFET Driver Circuit Requirements
With today's MOS drivers, there are several extraordinary requirements: 1. Low voltage application When the application of 5V switching power supply, at this time if the use of traditional totem pole structure, because the triode be only 0.7V up and down loss, resulting ...Read more -
Recognition of Insulated Layer Gate MOSFETs
Insulation layer gate type MOSFET alias MOSFET (hereinafter referred to as MOSFET), which has a cable sheath of silicon dioxide in the middle of the gate voltage and source drain. MOSFET is also N-channel and P-channel two categories, but each category is divided into en...Read more -
How to determine whether a MOSFET is good or bad?
There are two ways to tell the difference between a good and bad MOSFET: The first: qualitatively distinguish the advantages and disadvantages of MOSFETs First use the multimeter R × 10kΩ block (embedded 9V or 15V rechargeable battery), the negative pen (black) connected...Read more -
Ideas to solve the serious heat generation of MOSFETs
I do not know if you have found a problem, MOSFET act as a switching power supply equipment during operation sometimes serious heat, want to solve the heating problem of MOSFET, first we need to determine what causes, so we need to test, in order to find out where the pr...Read more -
The role of MOSFETs in circuits
MOSFETs play a role in switching circuits is to control the circuit on and off and signal conversion.MOSFETs can be broadly divided into two categories: N-channel and P-channel. In the N-channel MOSFET circuit, the BEEP pin is high to enable the buzzer response, and lo...Read more -
Take a look at MOSFETs
MOSFETs are insulating MOSFETs in integrated circuits.MOSFETs, as one of the most basic devices in the semiconductor field, are widely used in board-level circuits as well as in IC design.The drain and source of MOSFETs can be inte...Read more -
Basic MOSFET identification and testing
1.Junction MOSFET pin identification The gate of the MOSFET is the base of the transistor, and the drain and source are the collector and emitter of the corresponding transistor. The multimeter to R × 1k gear, with two pens to measure the forward and reverse resistance b...Read more -
Causes and Prevention of MOSFET Failure
The two main causes of MOSFET failure: Voltage failure: that is, the BVdss voltage between the drain and source exceeds the rated voltage of the MOSFET and reaches a certain capacity, causing the MOSFET to fail. Gate Voltage Failure: The gate suffers an abnormal voltage ...Read more -
What can I do to fix my MOSFET that is heating up badly?
Power supply circuits, or power supply circuits in the field of propulsion, inevitably use MOSFETs, which are of many types and have many functions. For switching power supply or propulsion applications, it is natural to use its switching function. Regardless of N-type o...Read more -
MOSFET conduction characteristics
MOSFET conductivity means that it is used as a switch, which is equivalent to a switch closing.NMOS is characterised as conducting when Vgs exceeds a limited value, which applies to the condition with the source connected to a grounded device, and only needs the gate vol...Read more
