MAX1044ESA from XBLW, in a SOP-8. 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 | BOOST | input | Oscillator frequency control input that increases internal oscillator frequency by a factor of 6 when connected to V+, or should be left open if using external oscillator. |
| 2 | CAP+ | passive | Negative terminal connection for the internal charge pump capacitor. |
| 3 | GND | power_in | Ground connection point; negative end of accumulator capacitor should be connected to this pin. |
| 4 | CAP- | passive | Positive terminal connection for the internal charge pump capacitor. |
| 5 | VOUT | power_out | Positive voltage output terminal rated for 0V to 9V; positive end of accumulator capacitor should be connected to this pin. |
| 6 | LV | input | Low voltage mode selection input that should be connected to ground when supply voltage is below 3.5V. |
| 7 | OSC | input | Oscillator frequency control input where an external capacitor reduces the internal oscillator frequency. |
| 8 | V+ | power_in | Power supply positive voltage input rated 1.5V to 9.0V; serves as chip substrate connection point. |
