■PCB layout consideration
For maximum accuracy, VCC and RSNS pins must be Kelvin connected to R3, to avoid errors caused by
voltage drops along the traces carrying the current from the VCC to the Source pin of the FET.
■Warning
The internal circuits of USBGT and RSNS consist of components that support 5V. Do not bias 7V or
above between VCC and these pins to prevent the IC from destruction. Do not use the device under
over-voltaged condition(for example shorting these terminals to low voltage node) even for short period
of time .
In normal operating condition with recommended application, the device controls voltage of these
terminals within 5V.
■Application information using other FET
You can replace 2SJ650 with 2SJ540 or SFT1342 .(2SJ650 is to be discontinued.)
In case of using 2SJ540/SFT1342, value of all resisters and capacitors will be the same as the case of
using 2SJ650.
Since SFT1342's package is different from that of 2SJ650/2SJ540, thermal design care must be
carefully done to assure a reliable design.
You must use the FET under the condition so that the power dissipation of FET does not exceed
allowable power dissipation.
