Monolithic Power Systems · Gate Drivers · SOIC-8
MP1924AHS-LF-Z from Monolithic Power Systems, 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 | Supply input powering the internal circuitry; place a decoupling capacitor to ground close to VDD (recommended 8.0V to 15.0V, absolute max -0.3V to +18V). |
| 2 | BST | power_in | Bootstrap positive supply for the internal floating high-side MOSFET driver; connect a bypass capacitor between BST and SW (BST to SW -0.3V to +18V, BST up to +115V). |
| 3 | DRVH | output | Floating high-side driver output, referenced to SW (DRVH to SW -0.3V to +18.3V). |
| 4 | SW | passive | Switching node, the high-side driver return (recommended -1.0V to +100V, absolute max -5V to +105V). |
| 5 | INH | input | Control signal input for the floating high-side driver, TTL-compatible with 185kΩ typical internal pull-down. |
| 6 | INL | input | Control signal input for the low-side driver, TTL-compatible with 185kΩ typical internal pull-down. |
| 7 | VSS | power_in | Chip ground. |
| 8 | DRVL | output | Low-side driver output (DRVL to VSS -0.3V to +18.3V). |
