A solid state power control (SSPC) controls flow of current from a power bus to an inductive load. The SSPC utilizes load sharing, in which a plurality of current supply paths are connected in parallel to control and share the flow of current between the power bus and the inductive load....
The following circuit diagram shows how to correctly connect two or more transistors in parallel. The emitter resistors make sure that the current sharing across the transistors is uniform and thus a thermal runaway situation is avoided. How to Calculate the Emitter Current Limiting Resistor in Par...

current share signal line for this method as shown in figure 2 left. External sharing control, such for example offered by Analog Devices LTC4370, is achieved by modulating the MOSFET voltage drops to offset the mismatch in the supply voltages (figure 2 right). This circuitry allows usag...
It needs to be connected to the "shaker" header and is supplied by the on board 5V regulator. The negative side is switched by the on board mosfet Please note, that the used mosfet needs to be a logic level type. Otherwise the shaker will not work!
·Over Load: 115%-140%; Constant current limiting, recovers automatically after fault condition is removed. ·Over Voltage: 115%-135%; Shut down o/p voltage, re-power on to recover. ·Over temp.: 95ºC(TSW1) Detect on the heatsink of PFC MOSFET, 90ºC(TSW2...
The drain of an N-channel MOSFET Q1 is also connected to point a of the secondary winding of the transformer T1. The drain of another N-channel MOSFET Q2 is connected to the other point b of the secondary winding of the transformer T1. The sources of each MOSFET are connected together ...
current sink. However, due to differences in propagation delays in the MOSFET gate drive, differences in transformer magnetizing and leakage inductance and other differences between the two converters12and14, the current sink characteristics are unequal. Trying to connect two devices in series, where ...
Using a single LDO for the supply is not always possible due to device availability and power dissipation limitations. The TIDA-050061 reference design solves this issue by using multiple LDOs configured to share current in parallel. The current sharing is achieved by using low-value ballast ...
