A high side current monitoring apparatus monitors a load current flowing into a load apparatus. The high side current monitoring apparatus includes a current mirror unit, an active high voltage unit, a voltage detection unit and a bias unit. The current mirror unit generates a mirrored current and outputs the mirrored current according to the load current. The active high voltage unit is electrically connected to the current mirror unit and receives the mirrored current and works in a linear area to withstand a high voltage. The voltage detection unit is electrically connected to the active high voltage unit and detects a voltage drop across the voltage detection unit and caused by the mirrored current. The bias unit is electrically connected to the active high voltage unit and provides the active high voltage unit with a bias.

High side current monitoring apparatus

An integrated power module packaging structure includes a housing, a first circuit board, a second circuit board, a first pin, a second pin and a third pin. The housing has a cavity. The second circuit board is located above the first circuit board, and both them are received in the cavity. A switching module is disposed on the first circuit board. A high side current/voltage detecting device and a driving device are disposed on the second circuit board. The first pin, the second pin and the third pin are disposed between the first circuit board and the second circuit board. The first pin connects the high side current/voltage detecting device and the switching module in series. The second pin connects the switching module. The driving device controls the switching module through the third pin.
