XL2903 from XINLUDA, in a SOP-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 | 1OUT | output | Output pin of comparator 1, an open-drain NPN output that sinks current when IN+ is higher than IN- (plus offset) and may be wired-AND with other open-collector outputs; absolute maximum output pin voltage is 36 V and output current is 20 mA. |
| 2 | 1IN- | input | Negative (inverting) input pin of comparator 1; the upper common-mode limit for this input is Vcc - 1.5 V and inputs must not go below ground by more than 0.3 V. |
| 3 | 1IN+ | input | Positive (non-inverting) input pin of comparator 1; the common-mode input range includes ground and this input may exceed Vcc, with either input rated to 30 V without damage for non-V devices (32 V for V-suffix). |
| 4 | GND | power_in | Ground pin for the device, which is the reference for the input and output voltage ratings. |
| 5 | 2IN+ | input | Positive (non-inverting) input pin of comparator 2; the common-mode input range includes ground and this input may exceed Vcc, with either input rated to 30 V without damage for non-V devices (32 V for V-suffix). |
| 6 | 2IN- | input | Negative (inverting) input pin of comparator 2; the upper common-mode limit for this input is Vcc - 1.5 V and inputs must not go below ground by more than 0.3 V. |
| 7 | 2OUT | output | Output pin of comparator 2, an open-drain NPN output that sinks current when IN+ is higher than IN- (plus offset) and may be wired-AND with other open-collector outputs; absolute maximum output pin voltage is 36 V and output current is 20 mA. |
| 8 | VCC | power_in | Supply pin; recommended supply is 2 V to 30 V for non-V devices or 2 V to 32 V for V-suffix devices, with single-supply or dual-supply operation possible. |
