SSP1839 from Shanghai Siproin Microelectronics, in a SOP-16. 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 | VDD | power_in | Power supply input, nominal 3.3V operation. |
| 2 | VT | input | External NTC temperature sensor analog signal input. |
| 3 | IP1 | input | Current channel A positive differential analog input, maximum ±50mV peak (35mV RMS). |
| 4 | IN1 | input | Current channel A negative differential analog input reference, maximum ±50mV peak (35mV RMS). |
| 5 | IP2 | input | Current channel B positive differential analog input, maximum ±50mV peak (35mV RMS). |
| 6 | IN2 | input | Current channel B negative differential analog input reference, maximum ±50mV peak (35mV RMS). |
| 7 | VP | input | Voltage channel differential analog input, maximum ±100mV peak (70mV RMS). |
| 8 | GND | power_in | Ground reference at 0V. |
| 9 | ZX | output | Voltage channel zero-crossing detection logic output. |
| 10 | I_leak | output | Channel B leakage/over-current alarm logic output. |
| 11 | CF | output | Energy pulse output or multiplex alarm function configurable via MODE register. |
| 12 | SEL | input | Interface selection input (0 = UART mode, 1 = SPI mode), internal pull-down to UART default. |
| 13 | SCLK | input | SPI serial clock input, maximum frequency 900 kHz, unused in UART mode. |
| 14 | RX/SDI | input | UART receive input (RX) at 4800 bps or SPI serial data input (SDI) in SPI mode. |
| 15 | TX/SDO | output | UART transmit output (TX) at 4800 bps or SPI serial data output (SDO), requires external pull-up resistor. |
| 16 | VPP | unconnected | Reserved pin, no connection required. |
