the motor current feedback. The ITRIP comparator threshold (typ 0.44 V) is referenced to VSS ground. A input

Over-current detection generates a hard shut down of all outputs of the gate driver and provides a latched fault

feedback at /FAULT pin. RCIN input/output pin is used to determine the reset time of the fault condition. As

soon as ITRIP threshold is exceeded the external capacitor connected to RCIN is fully discharged. The

capacitor is then recharged by the RCIN current generator when the over-current condition is finished. As soon

returns operational following the ontrol input pins according to section 3.1.

VCC, VSS and COM (Low Side Supply, Pin 1, 12,13)

VCC is the low side supply and it provides power both to input logic and to low side output power stage. Input

logic is referenced to VSS ground as well as the under-voltage detection circuit. Output power stage is

referenced to COM ground. COM ground is floating respect to VSS ground with a maximum range of operation

of +/-5.7 V. A back-to-back zener structure protects grounds from noise spikes.

The under-voltage circuit enables the device to operate at power on when a typical supply voltage higher than

This prevents the external power switches from critically low gate voltage levels during on-state and therefore

from excessive power dissipation. Please consult the individual output characteristic of the driven transistor.

VB1,2,3 and VS1,2,3 (High Side Supplies, Pin 18, 20, 22, 24, 26, 28)

VB to VS is the high side supply voltage. The high side circuit can float with respect to VSS following the

external high side power device emitter/source voltage. Due to the low power consumption, the floating driver

stage can be supplied by bootstrap topology connected to VCC. The device operating area as a function of the

supply voltage is given in Figure 12.

LO1,2,3 and HO1,2,3 (Low and High Side Outputs, Pin 14, 15, 16, 19, 23, 27)

Low side and high side power outputs are specifically designed for pulse operation such as gate drive of IGBT

and MOSFET devices. Low side outputs (i.e. LO1,2,3) are state triggered by the respective inputs, while high

side outputs (i.e. HO1,2,3) are edge triggered by the respective inputs. In particular, after an under voltage

condition of the VBS supply, a new turn-on signal (edge) is necessary to activate the respective high side

output, while after a under voltage condition of the VCC supply, the low side outputs switch to the state of their

respective inputs.
