An inverter circuit overcurrent protection device in which an overcurrent
detection resistor (Rs) is incorporated in a hybrid integrated circuit,
in which a detection voltage from the overcurrent detection resistor (Rs)
is divided by voltage dividing resistors (R.sub.1 and R.sub.2) and is
compared with a reference voltage in an overcurrent detection circuit,
for carrying out an overcurrent protection, and an external resistor is
connected in series or in parallel with one of the voltage dividing
resistors (R.sub.1 and R.sub.2) to change a division ratio so that the
level of overcurrent protection can be adjusted; and an embodiment
wherein, in the vicinity of a current detection terminal, a first pad
(P1) is connected to a detection voltage from the overcurrent detection
resistance, a second pad (P2) is connected to a detection voltage from
the amplifier, and a third pad (P3) is connected to the voltage dividing
resistors, and a bonding wire (10) is connected between the current
detection terminal one of said pads, to select one of a plurality of
overcurrent protection devices.
