Bi-directional current sensing using RDS(ON) of the MOSFETs detects over current conditions during positive and negative load currents without any external shunt resistors. An over current flag output provides over current status without shutting down, enabling full external control over OCP protection sequences. Independent HIN and LIN inputs offers independent control on HO and LO. Internal shoot-thru prevention logic provides safe operation by eliminating simultaneous ON state in the output MOSFET. 3 www.irf.com (c) 2014 International Rectifier February 21, 2014 IRS20965 Qualification Information Qualification Level Moisture Sensitivity Level Machine Model ESD Human Body Model IC Latch-Up Test RoHS Compliant Industrial Comments: This family of ICs has passed JEDEC's Industrial qualification.
