・Vin(+), Vin(-) (Power supply pin for DC/DC converter)
・GND(Ground pin for drive curcuit)
・INA, INB, XRST(Control input pin, XRST input pin)
The INA, INB and XRST pin is a pin used to determine output logic.
And XRST is in charge of setting back the FLT pin.
・FLT(Fault output pin)
The FLT pin is an open drain pin used to output a fault signal when desaturation function is activated, and will be cleared at the rising edge of FLT.
・RDY(Ready output pin)
The RDY pin shows the status of three internal protection features which are 5VDC UVLO, OUT(H) UVLO, and output state
feedback (OSFB). The term ‘output state feedback’ shows whether output internal logic is high or low corresponds to input logic or not.
・OUT(Output pin)
The OUT pin is a pin used to drive the gate of a power device.
・CLAMP(Miller clamp pin)
The CLAMP pin is a pin for preventing increase in gate voltage due to the miller current of the power device connected to OUT pin.
・DESAT(Desaturation protection pin)
The DESAT pin is a pin used to detect desaturation of IGBT/MOSFET. When the DESAT pin voltage exceeds V
DESAT
, the DESAT function
will be activated. This may cause the IC to malfunction in an open state. To avoid such trouble, short-circuit the DESAT pin to the COM pin
if the desaturation protection is not used. In order to prevent the wrong detection due to noise, the noise mask time t
DESATFIL
is set.
・COM(Common pin)
COM pin is a pin to be connected to the emitter / source of the power device.
