The load was connected to the power source and an npn transistor acted as a switch to ground.
High side switch transistor.
It consists of a mosfet a gate driver with charge pump and multiple protection and diagnosis features.
This time however the emitter is tied high.
For driving the mosfet in high side configuration ir2110 gate driver ic was used.
The circuit above is called a low side switch because the switch our transistor is on the low ground side of the circuit.
We ll need a more complex circuit to implement a practical high side power on switch.
Ir2110 is a high low side gate driver ic which is used with power mosfet and igbt.
A gate driver is a specially designed circuit that is used to drive the gate of mosfet or.
With our switch portfolio you can find a protection solution for your inductive capacitive and resistive loads ensuring your design is scalable and robust.
All the circuits had similar topologies.
Part 7 covered using transistors to switch loads that require higher currents or voltages than the microcontroller can handle.
Because of how transistors work these can be a little more difficult to use in an arduino or raspberry pi circuit.
Profet protected field effect transistors is our high side smart power switch brand.
Typically these use a pnp bjt or p channel mosfet.
With adjustable current limit high accuracy current sense and a wide range of rdsons our smart high side switches provide the optimal solution for your specific use case.
The mosfet were used as high side switches in the circuit.
In addition several protection features are integrated.
For example short circuit protection can protect the mosfet if a short to ground battery occurs.
Which means that pnp transistor shown in the first image will always be on regardless of the i o pin state.
Similar to the npn circuit the base is our input and the emitter is tied to a constant voltage.
Alternatively we can use a pnp transistor to create a high side switch.
This transistor connects between v and the load.
Since the switching element the transistor was at ground it.
