Logic inputs for high side gate driver outputs (HO1,2,3), out of phase [IRS213(6,63,65,66,67,68)]

Logic inputs for high side gate driver outputs (HO1,2,3), in Phase (IRS21362)

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

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

Note: LIN, HIN, EN, and ITRIP are internally clamped with a 5.2 V zener diode.
