Description

VCC

Low side and logic fixed supply

VSS

HIN1,2,3

HIN1,2,3

LIN1,2,3

Logic ground

Logic inputs for high side gate driver outputs (HO1,2,3), out of phase [IR213(6,63,65,66,67,68)]

Logic inputs for high side gate driver outputs (HO1,2,3), in phase (IR21362)

Logic input for low side gate driver outputs (LO1,2,3), out of phase

FAULT

EN

ITRIP

RCIN

COM

Indicates over-current (ITRIP) or low-side undervoltage lockout has occurred. Negative logic, open-

drain output

Logic input to enable I/O functionality. I/O logic functions when ENABLE is high (i.e., positive logic)

No effect on FAULT and not latched

Analog input for overcurrent shutdown. When active, ITRIP shuts down outputs and activates FAULT

and RCIN low. When ITRIP becomes inactive, FAULT stays active low for an externally set time

TFLTCLR, then automatically becomes inactive (open-drain high impedance).

External RC network input used to define FAULT CLEAR delay, TFLTCLR, approximately equal to R*C.

When RCIN>8 V, the FAULT pin goes back into open-drain high-impedance

Low side gate drivers return

VB1,2,3 High side floating supply

HO1,2,3 High side gate driver outputs

VS1,2,3 High voltage floating supply return

LO1,2,3 Low side gate driver outputs

Note: All input pins and the ITRIP pin are internally clamped with a 5.2 V zener diode.
