HIN1,2,3 Logic inputs for high side gate driver outputs (HO1,2,3), out of phase (IR2136/IR21363(5)(6)(7)(8)
HIN1,2,3 Logic inputs for high side gate driver outputs (HO1,2,3), in phase (IR21362)
LIN1,2,3 Logic inputs for low side gate driver outputs (LO1,2,3), out of phase
FAULT
Indicates over-current (ITRIP) or low-side undervoltage lockout has occured. Negative logic,
open-drain output
EN
Logic input to enable I/O functionality. Positive logic, i.e. I/O logic functions when ENABLE is
high. No effect on FAULT and not latched
ITRIP
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>8V, the FAULT pin goes back into open-drain high-impedance
