LTC2802IDE#TRPBF from Analog Devices, in a DFN-12-EP(3x4). 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 | RIN | input | RS-232 receiver input with an internal 5kΩ termination; absolute maximum rating is -25V to 25V. |
| 2 | TOUT | output | RS-232 driver output that is protected so it can be shorted to ground or up to ±15V without damage. |
| 3 | VCC | power_in | Input supply, 1.8V to 5.5V; bypass to GND with a 1µF capacitor. |
| 4 | VDD | power_out | Generated positive supply for the RS-232 driver (7V); connect a 1µF capacitor between VDD and GND. |
| 5 | SW | passive | Switch pin for the DC-DC converter; connect a 10µH inductor between SW and VCC. |
| 6 | GND | power_in | Ground. |
| 7 | CAP | passive | Charge pump capacitor node for the generated negative supply; connect a 220nF capacitor between CAP and SW. |
| 8 | PS | input | Power supply control pin, referenced to VL, that enables the integrated DC-DC converter. |
| 9 | MODE | input | Mode control pin, referenced to VL; see Table 1 of the datasheet for the mode functions. |
| 10 | VL | power_in | Logic supply, 1.8V to 5.5V, for the receiver outputs, driver inputs and control inputs; bypass with a 220nF capacitor to GND if not tied to VCC. |
| 11 | TIN | input | Driver input referenced to VL. |
| 12 | ROUT | output | Receiver output referenced to VL; short-circuit protected to GND/VCC/VL and high impedance in Shutdown mode. |
| 13 | VEE | power_out | Generated negative supply for the RS-232 driver (-6.3V); connect a 1µF capacitor between VEE and GND. This is the backside exposed thermal pad, which must be soldered to the PCB. |
