TD352IDT from STMicroelectronics, 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 | IN | input | Control input internally clamped 5-7V with turn-on threshold 1.0V and turn-off threshold 4.2V |
| 2 | VREF | power_out | Reference voltage output 5.0V nominal (4.85-5.15V at 25°C) with 10mA maximum output current; 10-100nF decoupling capacitor required |
| 3 | CD | passive | Timing capacitor pin for programmable turn-on delay; delay time approximately 0.7 × Rd(kΩ) × Cd(nF) microseconds |
| 4 | DESAT | input | Desaturation protection input; output driven low when DESAT voltage exceeds VH-2V; internal source current 250µA for blanking time |
| 5 | CLAMP | output | Miller clamp output activated when gate voltage drops below 2V threshold; maximum clamp voltage VL+4V at 500mA |
| 6 | VL | power_in | Negative supply terminal providing signal ground reference; maximum supply voltage 28V between VH and VL |
| 7 | OUT | output | Gate drive output capable of sinking 1700mA and sourcing 1300mA (typical at 25°C) |
| 8 | VH | power_in | Positive supply voltage input with absolute maximum 28V relative to VL; UVLO protection thresholds 9-12V |
