Lead Definitions

Symbol Description

VCC

Low side and logic fixed supply

VSS

Logic Ground

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

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).

RCIN

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

COM

Low side gate driver return

VB1,2,3

High side floating supply

HO1,2,3

High side gate driver outputs

VS1,2,3

High voltage floating supply returns

LO1,2,3

Low side gate driver output

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