L6598D013TR from STMicroelectronics, in a SO-16. 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 | CSS | passive | Soft-start timing capacitor; the soft-start constant kSS is 0.15 s/µF typical (0.115 to 0.185 s/µF), so the soft-start time depends only on this capacitor. |
| 2 | Rfstart | input | Soft-start frequency setting pin, to be driven from a low impedance voltage source, with forced input voltage limited to -0.3 V to 5 V. |
| 3 | Cf | passive | Oscillator frequency setting capacitor pin (470 pF in the test conditions), with forced input voltage limited to -0.3 V to 5 V. |
| 4 | Rfmin | input | Minimum oscillation frequency setting pin, to be driven from a low impedance voltage source, with forced input voltage limited to -0.3 V to 5 V. |
| 5 | OPout | output | Sense op amp output, with low impedance; the forced output voltage is limited to 4.6 V. |
| 6 | OPon- | input | Sense op amp inverting input, high impedance, with input common mode range of -0.2 V to 3 V. |
| 7 | OPon+ | input | Sense op amp non-inverting input, high impedance, with input common mode range of -0.2 V to 3 V. |
| 8 | EN1 | input | Half bridge latched enable, active high with a 0.6 V typical threshold (0.56 to 0.64 V) that latches the device in shutdown. |
| 9 | EN2 | input | Half bridge unlatched enable, active high with a 1.2 V typical threshold (1.05 to 1.35 V) that restarts a soft-start sequence. |
| 10 | GND | power_in | Ground reference; the internal clamping Zener of the Vs pin is connected between GND and Vs. |
| 11 | LVG | output | Low side driver output, with 250 mA typical source and 450 mA typical sink capability and 80/40 ns typical rise/fall times at 1 nF load. |
| 12 | Vs | power_in | Supply voltage with internal Zener clamp at 14.6 to 16.6 V; it must not be supplied by a low impedance voltage source and the clamp current is limited to 25 mA, with recommended supply range of 10 V to Vcl. |
| 13 | N.C. | unconnected | Not connected. |
| 14 | OUT | passive | High side driver reference, with recommended voltage range of -1 V to VBOOT - Vcl and output slew rate of ±50 V/ns (repetitive). |
| 15 | HVG | output | High side driver output, with 250 mA typical source and 450 mA typical sink capability and 80/40 ns typical rise/fall times at 1 nF load. |
| 16 | Vboot | power_in | Bootstrapped floating supply; recommended floating supply rail is 500 V with absolute maximum of 618 V and slew rate of ±50 V/ns (repetitive). |
