It is the glue between a PWM controller and the power stage in a synchronous buck converter, typically found on voltage regulator modules for processor cores, telecom line cards, and base station power supplies. ## 20 ns edges — dead-time and switching loss budget The 20 ns typical rise and fall time sets the transition window where both FETs are off. A controller with adaptive dead-time can use this edge rate to minimise body-diode conduction loss without risking shoot-through. The 20 ns spec is fast enough for switching frequencies up to about 500 kHz before the dead-time eats into the duty-cycle range. Supply range of 4.15 V to 7.5 V means this driver runs from a 5 V or 7 V rail, not the 12 V bus common on older half-bridge drivers. The gate drive voltage is therefore limited to the supply rail minus the bootstrap diode drop — about 4.5 V to 7 V at the high-side gate. That is enough to fully enhance a logic-level N-channel MOSFET with a Vgs(th) below 2.5 V. The bootstrap pin is rated to 30 V maximum, which caps the input voltage of the buck converter at about 24 V nominal with margin. A 48 V input bus would exceed the bootstrap rating and damage the driver. The 125°C upper limit is typical for a junction-temperature-rated driver; the actual case temperature will be lower depending on the thermal impedance of the 8-SOIC footprint. The 8-SOIC package is a common, low-cost footprint that rework techs can replace with hot air — no preheater needed.","metaTitle":"ADP3412JR Dual MOSFET Driver, Half-Bridge, 20ns, 8-SOIC","metaDescription":"ADP3412JR dual N-channel MOSFET driver in half-bridge configuration. 20 ns rise/fall time, 4.15 V to 7.5 V supply, 30 V bootstrap max.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":[],"specifications":{"Package":"Bulk","Gate Type":"N-Channel MOSFET","Input Type":"Non-Inverting","Channel Type":"Synchronous","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.15V ~ 7.5V","Number of Drivers":"2","Driven Configuration":"Half-Bridge","Operating Temperature":"0°C ~ 125°C (TJ)","Rise / Fall Time (Typ)":"20ns, 20ns","Supplier Device Package":"8-SOIC","Logic Voltage - VIL, VIH":"0.8V, 2V","High Side Voltage - Max (Bootstrap)":"30 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.87","stockQuantity":0,"priceTiers":[{"qty":344,"price":"$0.87000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d8aa10cabeae9895ff88950602da30d6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADP3412JR be used with 3.3V logic?","answer":"The logic input thresholds are specified at 0.8 V for VIL and 2 V for VIH. A 3.3 V logic output with a 2 V VIH threshold will drive the input reliably, provided the driver's supply voltage is within the 4.15 V to 7.5 V range.
