LNBH26LSPQR from STMicroelectronics, in a QFN-24(4x4). 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 | GND | power_in | Analog circuit ground, to be connected directly to the exposed pad. |
| 2 | GND | power_in | Analog circuit ground, to be connected directly to the exposed pad. |
| 3 | LX-A | output | Drain of the channel A integrated N-channel power MOSFET of the DC-DC step-up converter. |
| 4 | P-GND | power_in | DC-DC converter power ground, to be connected directly to the exposed pad. |
| 5 | LX-B | output | Drain of the channel B integrated N-channel power MOSFET of the DC-DC step-up converter. |
| 6 | ADDR | input | Sets one of the two available I²C bus addresses through the voltage level applied to this pin (see Table 15 of the datasheet for address pin characteristics). |
| 7 | SCL | input | Serial clock input from the I²C bus. |
| 8 | SDA | bidirectional | Bidirectional serial data line to and from the I²C bus. |
| 9 | ISEL | passive | A resistor RSEL connected between ISEL and GND sets the linear regulator current limit, which is the same for channels A and B. |
| 10 | NC | unconnected | Not internally connected; set floating if not used. |
| 11 | VUP-B | power_in | Input of the channel B linear post-regulator, monitored by the channel B step-up controller to keep a minimum dropout across the linear pass transistor. |
| 12 | VOUT-B | power_out | Output of the channel B integrated very low drop linear regulator, whose voltage is selected via the DATA1 register per Table 13. |
| 13 | GND | power_in | Analog circuit ground, to be connected directly to the exposed pad. |
| 14 | GND | power_in | Analog circuit ground, to be connected directly to the exposed pad. |
| 15 | GND | power_in | Analog circuit ground, to be connected directly to the exposed pad. |
| 16 | BYP | passive | Bypass pin for internal pre-regulator filtering, intended only for an external ceramic capacitor; any connection to external current or voltage sources may cause permanent damage. |
| 17 | VCC | power_in | IC DC-DC power supply input, 8 V to 16 V. |
| 18 | GND | power_in | Analog circuit ground, to be connected directly to the exposed pad. |
| 19 | GND | power_in | Analog circuit ground, to be connected directly to the exposed pad. |
| 20 | VOUT-A | power_out | Output of the channel A integrated very low drop linear regulator, whose voltage is selected via the DATA1 register per Table 13. |
| 21 | VUP-A | power_in | Input of the channel A linear post-regulator, monitored by the channel A step-up controller to keep a minimum dropout across the linear pass transistor. |
| 22 | DSQIN-A | input | Logic input for channel A 22 kHz tone control (TTL compatible); it acts as DiSEqC envelope input or external 22 kHz TTL input depending on the EXTM-A bit, and should be pulled high if the tone is activated only by the TEN-A bit. |
| 23 | GND | power_in | Analog circuit ground, to be connected directly to the exposed pad. |
| 24 | DSQIN-B | input | Logic input for channel B 22 kHz tone control (TTL compatible); it acts as DiSEqC envelope input or external 22 kHz TTL input depending on the EXTM-B bit, and should be pulled high if the tone is activated only by the TEN-B bit. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
