COS44263 from COSINE, in a SOT23-5. 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 | NC | unconnected | No connection; this pin is not connected internally on the COS44263 variant. |
| 2 | VDD | power_in | Bias supply for the MOSFET driver, rated 4.5V to 25V with respect to the Ground pin, and should be bypassed with local ceramic capacitors (1.0 µF suggested). |
| 3 | IN | input | High-impedance TTL/CMOS compatible control input with 300 mV of hysteresis between the high and low thresholds, which prevents output glitching on slow input edges. |
| 4 | GND | power_in | Device return pin that should have a low-impedance connection to the bias supply source return, and which carries high peak current when the capacitive load is discharged. |
| 5 | OUT | output | Low-impedance CMOS push-pull output with pull-down and pull-up devices of equal strength, so rise and fall times are equivalent. |
