In the NC IXBD4410, this output indicates a fault condition of either device of the chipset. A "high" indicates no fault, A "low" indicates that either overcurrent,V DD or VEE under-voltage occurred. In case of overcurrent, this output will remain active "low" until the next input cycle of the respective driver. In case of under-voltage, this output will remain "low" until the proper voltage is restored. The IXBD4411 does not have a FLT output,and its pin 8 should be tied to LG No Connection (IXBD 4411) IM 9 Current sense or desaturation detection input. This input is active only while the OUT pin is "high" (on). When the OUT pin is "low" (off) this input is pulled to ground through a 70 Ω resistor. Any voltage at this pin above the threshold of .3 V typical, will turn the output (pin 15) off. This pin is used for power device overcurrent protection. KG 10 Kelvin ground. This ground is used as Kelvin connection for overcurrent or desaturation sensing. LG 11 Logic and power ground. CB 12 Capacitor terminals for negative charge pump (V EE); "+" CA 13 terminal is CB (pin 12). VEE 14 Negative supply terminal(substrate) OUT 15 Gate drive output. In the IXBD4410 this output responds to the INL signal. A "high" at INL will turn it on ("high"), a "low" will turn it off ("low"). In the IXBD4411, this output responds to the transmitted signal from the companion IXBD4410. A "high" at INH of the IXBD4410 drives will turn it on ("high"). A "low" will turn it off ("low"). This output will turn off ("low") also in response to any fault condition. VDD VDD NC OUT NC VEE T- CA T+ CB R- LG R+ KG NC IM Pin Description IXBD4410 (Low-Side Driver) Sym. Pin Description of IXBD 4410/4411 VDD 1 Positive power supply. 16 INL 2 Logic input signal referenced to NC LG (logic ground). In the IXBD4410. A "high" to this pin turns on its gate drive output and resets its fault logic. A "low" to this pin turns off the gate drive output. In the IXBD4411 this pin is not used and should be connected to its ground (LG). No Connection (IXBD 4411) INH 3 Logic input signal referenced to NC LG (logic ground). In the IXBD4410, this signal is transmitted to the IXBD4411 "high-side" driver through pins 4 and 5 (T- and T+). A "high" to this pin turns on the IXBD4411 gate drive output and resets its fault logic. A "low" to this pin turns off the IXBD4411 gate drive output. In the IXBD4411 this pin is not used and should be connected to its ground (LG). No Connection (IXBD 4411) T- 4 Transmitter output complemen- T+ 5 tary drive signals. Direct drive of the low signal transformer, which is connected to the receiver of the chipset's companion device. In the IXBD4410, this signal transmits the on/off command to its companion IXBD4411. In the IXBD4411, this signal transmits the fault indication to its companion IXBD4410 driver. R- 6 Receiver input complementary R+ 7 signal. Directly connected to the low signal transformer, which is driven by the chipset's compa- nion device. In the IXBD4410, this input receives the fault indication from its companion IXBD4411 driver. In the IXBD4411, this input receives the on/off command from its companion IXBD4410 driver. VEE T A B Connected to Pin 14 (substrate) |
