The Executive module with a MOSFET type transistor with a pair of channels P to control devices with higher current consumption than allowed by the control system, for example, minikomputer Raspberry Pi. The module provides the supply voltage from 4.5 V to 40 V with current consumption up to 16 A.
The use of the switch MOSFET
The national security Council use, just connect power and ground (pins VIN and GND) and control the voltage VOUT with built-in sunroof switch. To use an external switch, connect it between the GND and SW after setting the embedded switch in the OFF position.
Connection example external switch
Even in the OFF position, it is possible to monitor the status of a switch via a digital signal (e.g., a microcontroller) via pin IT. Low status or lack of connection leaves the switch in the OFF position, the setting at this place approx. 1 V changes the switch status to "on". The maximum value of the voltage on the pine IT can be 30 Volts, regardless of the voltage VIN.
Conclusions are fields solders for wlutowanie goldpin connectors (2.54 mm pitch). Thanks to them, it is possible to connect the system with the breakout Board or the main module (for example, STM32Discovery or Arduino) via wires.
Module includes the screw connections and connectors goldpin.
For the circuit MOSFET power nagrzewająca plate is proportional to the square of the flowing current. With a typical current of 6 A reaches the temperature of 55 °C and it becomes wyczuwalnie warmth and safety. With appropriate heat dissipation is possible to obtain a value of 16 A. however, it is recommended to take special precautions, since the transistor is a MOS transistor may be heated to a temperature of 150 °C.
