IR21844STRPBF-JSM from JSMSEMI, in a SOP-14. 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 | IN | input | High- and low-side logic signal input, referenced to VSS with range VSS to VSS+5V. |
| 2 | SD | input | Active-low logic shutdown input that turns off both high- and low-side outputs. |
| 3 | VSS | power_in | Digital (logic) ground, recommended -5V to 5V relative to COM. |
| 4 | DT | input | Programmable dead-time input set by an external resistor RDT, range VSS to VCC. |
| 5 | COM | power_in | Power ground, the reference for the voltage ratings. |
| 6 | LO | output | Low-side gate drive output, range 0V to VCC. |
| 7 | VCC | power_in | Low-side supply voltage, recommended 10V to 20V (absolute max 25V). |
| 8 | NC | unconnected | No connect (empty pin). |
| 9 | NC | unconnected | No connect (empty pin). |
| 10 | NC | unconnected | No connect (empty pin). |
| 11 | VS | power_in | High-side floating ground, recommended -9V to 700V. |
| 12 | HO | output | High-side gate drive output, range VS to VB. |
| 13 | VB | power_in | High-side floating supply, recommended VS+10V to VS+20V (absolute max 725V). |
| 14 | NC | unconnected | No connect (empty pin). |
