ISO5452QDWRQ1 from Texas Instruments, in a SOIC-16-300mil. 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 | VEE2 | power_in | Output negative supply; connect to GND2 for unipolar supply applications. |
| 2 | DESAT | input | Desaturation voltage detection input for IGBT overcurrent fault monitoring. |
| 3 | GND2 | power_in | Gate drive common ground, connect to IGBT emitter. |
| 4 | OUTH | output | Positive gate drive voltage output with 2.5A maximum peak pull-up current capability. |
| 5 | VCC2 | power_in | Most positive output supply potential, rated 15V to 30V. |
| 6 | OUTL | output | Negative gate drive voltage output with 5A maximum peak pull-down current capability. |
| 7 | CLAMP | output | Active Miller clamp output sinking up to 2.5A for parasitic turn-on suppression in unipolar operation. |
| 8 | VEE2 | power_in | Output negative supply; connect to GND2 for unipolar supply applications. |
| 9 | GND1 | power_in | Input ground for low-voltage control side. |
| 10 | IN+ | input | Non-inverting gate drive voltage control input, CMOS compatible, 0.7×VCC1 high threshold. |
| 11 | IN- | input | Inverting gate drive voltage control input, CMOS compatible, 0.3×VCC1 low threshold. |
| 12 | RDY | output | Power-good status output, active high when both input and output supplies are adequate. |
| 13 | FLT | output | Fault output indicating desaturation fault condition, active low during DESAT. |
| 14 | RST | input | Reset input to clear fault latch; requires minimum 800ns low pulse when RDY is high. |
| 15 | VCC1 | power_in | Positive input supply voltage, 2.25V to 5.5V rating. |
| 16 | GND1 | power_in | Input ground for low-voltage control side. |
