UCC24612-1DBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VG | output | Gate-drive output for the controlled SR N-channel MOSFET. Connect through a small series resistor with short PCB tracks. Delivers >1 A peak source and >4 A peak sink current; output is clamped at ~9.5 V (VREG). Avoid pulling VG to VS through less than 50 kΩ due to the weak internal pull-up after initial fast turn-on. |
| 2 | VS | power_in | Internal ground reference of the UCC24612 and the low-side sense node for the SR MOSFET VDS drop. Route as a dedicated Kelvin trace to the MOSFET source and avoid sharing with power-path currents to minimize parasitic inductance error. |
| 3 | REG | power_out | Internal LDO output that regulates VDD down to a well-regulated 9.5 V rail used for the gate driver clamp and internal bias. Bypass to VS with a 1.5-2.2 µF ceramic capacitor. Absolute-maximum voltage on REG is 12 V. |
| 4 | VDD | power_in | Bias supply input to the internal LDO (feeds REG). Recommended operating range 4-28 V (abs-max 30 V); bypass with ≥1 µF to VS. In low-side SR configurations connect directly to the output rail; in high-side SR configurations derive VDD from the SR MOSFET drain via an R-C-D network (see Power Supply Recommendations). |
| 5 | VD | input | MOSFET drain-voltage sensing input. Connect directly to the SR MOSFET drain with a dedicated trace, avoiding shared power-path routing to preserve VDS-sense fidelity. Rated for continuous drain sensing up to 230 V (abs-max) with sub-microamp leakage; VG turn-on/turn-off thresholds are typically -240 mV / -9 mV referred to VS. |
