UCC27523D

Texas Instruments · Gate Drivers · SOIC-8

UCC27523D from Texas Instruments, 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 ENA input Channel A enable input; high enables OUTA, low disables OUTA independent of INA state; floating enables output
2 INA input Channel A inverting input with TTL/CMOS thresholds (1.0-1.4V low, 1.9-2.3V high) and 0.9V hysteresis; output held low when input floating
3 GND power_in Ground reference; all signal levels measured with respect to this pin
4 INB input Channel B inverting input with TTL/CMOS thresholds (1.0-1.4V low, 1.9-2.3V high) and 0.9V hysteresis; output held low when input floating
5 OUTB output Channel B output; 5A peak source/sink current; rise time 7-18 ns, fall time 6-10 ns; swings GND to VDD
6 VDD power_in Auxiliary power supply input; 4.5-18V operating range with 4.2V UVLO on-threshold and 0.3V hysteresis
7 OUTA output Channel A output; 5A peak source/sink current; rise time 7-18 ns, fall time 6-10 ns; swings GND to VDD
8 ENB input Channel B enable input; high enables OUTB, low disables OUTB independent of INB state; floating enables output
