Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...
If you have an application in which a MOSFET is already used to switch a load, it is relatively easy to add short-circuit or overload protection. Here we make use of the internal resistance RDS(ON), ...
To prevent a motor from burning up, you must provide a means of protecting it from overcurrent (overload, short circuit, or ground fault). If you can remember not to confuse motor protection with ...
In Part 1, we saw why we must separate overload protection from fault and short circuit protection for motor circuits. But correctly sizing these different devices can be confusing. And if you follow ...
MOSFETs are widely used as power switching elements in regulators and motor controllers. They can be either discrete devices or integrated into ICs in various H-bridge configurations. A common ...
Toshiba: SSM14N956L, a small and thin common-drain MOSFET featuring very low On-resistance (Graphic: Business Wire) KUALA LUMPUR, May 18 (Bernama) -- Toshiba Electronic Devices & Storage Corporation ...
The need to improve reliability while reducing product cost has seen a proliferation of self-protected MOSFETs in the automotive sector. At the same time, consumer demand for more 'feature rich' ...
A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...
Electric drives require effective protection against overloads and short circuits. Both phenomena cause motor disruption and create a risk of damage to the motor. This could lead to a potentially ...
