LM5104MX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Positive gate drive supply with operating range of 9-14V DC; requires local ESR/ESL bypass capacitor to VSS placed as close to IC as possible. |
| 2 | HB | power_in | High-side bootstrap power supply with operating range VHS + 8V to VHS + 14V DC; connect bootstrap capacitor positive terminal placed as close to IC as possible. |
| 3 | HO | output | High-side gate driver output with peak pullup current of 1.6A and pulldown current of 1.8A; connect to high-side MOSFET gate via short low-inductance path. |
| 4 | HS | passive | High-side MOSFET source connection and bootstrap capacitor negative terminal reference; withstands -1V to 100V relative to VSS and slew rate <50V/ns. |
| 5 | RT | input | Deadtime programming pin accepting external resistor (5kΩ to 100kΩ range) to ground for setting adaptive delay from 90ns to 200ns; biased at 2.7-3.3V nominal with current limit of 0.75-2.25mA. |
| 6 | IN | input | Control input logic with threshold levels VIL=0.8-1.8V and VIH=1.8-2.2V where logic 1 enables high-side driver (HO high, LO low) and logic 0 enables low-side driver (HO low, LO high). |
| 7 | VSS | power_in | Ground return providing zero-volt reference for all input and output signals with recommended local bypass capacitor placement. |
| 8 | LO | output | Low-side gate driver output with peak pullup current of 1.6A and pulldown current of 1.8A; connect to low-side MOSFET gate via short low-inductance path. |
