NOTE:

▪ W1 and W2, as well as V1 and V2< must be externally connected to each other.

▪ If not using the Current Limiter (OCL) function, leave the OCL and SD pins open, but the SD pin should be connected to

GND if significant external noise is observed.

even though a 1 MΩ pull-up resistor is built-in at the ¯F¯¯¯O¯ pin. Note that connecting to the 3.3 V or 5 V supply without a pull-up

resistor disables the TSD function (however, low-side UVLO protection and OCP function remain active).

and COM2 pins.

▪ To avoid malfunctions resulting from noise interference, the traces must be as short as possible between the IC and the

▪ To avoid malfunctions resulting from noise interference, place a 0.01 to 0.1 μF ceramic capacitor between the VCC1 and

COM1 pins, as well as between the VCC2 and COM2 pins. Also, the traces between them must be as short as possible.

between the LS and COM2 pins, and the IC must be as short and wide as possible.

▪ To avoid malfunction, the wiring between the LS and COM2 pins should be as short as possible. When wiring cannot be

shortened sufficiently, insert a fast diode between LS and COM2.

detection, the time constant should be set to be 0.2 μs or shorter. Care should be taken because destruction of the IPM may

be caused due to detection delay when the time constant of filter is set to be 0.2 μs or longer, because a filter (1.5 μs(min)) is

incorporated in the OCP circuit of the IPM.
