It's part of the Automotive series and carries AEC-Q100 qualification, making it suitable for under-hood and chassis-domain power electronics where the ambient temperature can push past 105°C. The driver delivers 3A peak source and 4A peak sink current, enough to charge and discharge the gate capacitance of large TO-220 or D2PAK MOSFETs in the 10ns range. ## What the 3A/4A drive and 100V bootstrap mean for your power stage The 3A source, 4A sink peak output lets you drive MOSFETs with substantial gate charge — think 30nC to 60nC parts — without excessive switching loss. The asymmetric sink/source ratio favors faster turn-off, which reduces shoot-through risk in hard-switched bridges. The bootstrap supply is rated for 100V maximum on the high side, so this driver handles 48V to 72V nominal bus voltages with margin, or 12V automotive rails with plenty of headroom for load-dump transients. Rise and fall times are both 10ns typical, which keeps the cross-conduction window tight but does demand careful layout — the gate loop inductance needs to stay under a few nH to avoid ringing. ## Supply range and logic thresholds for the BOM planner Operating supply is 8V to 18V, which covers the standard automotive battery range from cold-crank (down to about 6V with some sag) through nominal 12V to the 16V alternator regulation point. The logic inputs accept both inverting and non-inverting signals with VIL at 1V and VIH at 2.1V, so they interface directly with 3.3V or 5V MCU/FPGA I/O without external level shifting. That saves two resistors and a transistor per channel on the BOM. ## Package and thermal: 14-HTSSOP with exposed pad The 14-TSSOP package with exposed pad (0.173\" wide, 4.40mm) is a surface-mount footprint that hand-solders fine with a hot-air station — the exposed pad needs a thermal via array to the ground plane to pull heat out of the die. The operating junction temperature range is -40°C to 140°C, so this part lives comfortably in engine bay or transmission control modules where ambient can hit 125°C. The supplier device package is listed as 14-HTSSOP; the exposed pad is the same footprint as a standard TSSOP-14 but with the thermal slug underneath. ## Lifecycle and sourcing: active, AEC-Q100, no LTB risk The ISL78424AVEZ-T7A has an Active lifecycle status per the manufacturer. It's ROHS3 compliant and carries full AEC-Q100 automotive qualification. Cut Tape options are also listed for prototype quantities.","metaTitle":"ISL78424AVEZ-T7A Half-Bridge Gate Driver, AEC-Q100, 3A/4A","metaDescription":"Renesas ISL78424AVEZ-T7A automotive half-bridge N-channel MOSFET driver. 3A source, 4A sink peak output, 100V bootstrap, -40°C to 140°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Gate Type":"N-Channel MOSFET","Input Type":"Inverting, Non-Inverting","Channel Type":"Synchronous","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"8V ~ 18V","Number of Drivers":"2","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 140°C (TJ)","Rise / Fall Time (Typ)":"10ns, 10ns","Supplier Device Package":"14-HTSSOP","Logic Voltage - VIL, VIH":"1V, 2.1V","High Side Voltage - Max (Bootstrap)":"100 V","Current - Peak Output (Source, Sink)":"3A, 4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.51","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.51000","currency":"USD"},{"qty":10,"price":"$4.94500","currency":"USD"},{"qty":25,"price":"$4.67440","currency":"USD"},{"qty":100,"price":"$4.05130","currency":"USD"},{"qty":250,"price":"$3.84356","currency":"USD"},{"qty":500,"price":"$3.44882","currency":"USD"},{"qty":1250,"price":"$3.27320","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dee5a90dc4732d34eb3365c715ffeaad.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ISL78424AVEZ-T7A have AEC-Q100 automotive qualification?","answer":"Yes, it is part of the Automotive, AEC-Q100 series.
