SSP1837 from Shanghai Siproin Microelectronics, 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 | VDD | power_in | Power supply (+3.3V); must be maintained at 3.0V to 3.6V during IC operation. |
| 2 | IP | input | Positive input for current channel; fully differential with maximum signal range of ±50mV (±1.5V maximum with ESD protection). |
| 3 | IN | input | Negative input for current channel; fully differential with maximum signal range of ±50mV (±1.5V maximum with ESD protection). |
| 4 | VP | input | Positive input for voltage channel; differential with maximum signal range of ±200mV (±1.5V maximum with ESD protection). |
| 5 | GND | power_in | Ground reference. |
| 6 | CF | output | High frequency pulse output for active power with 38uS fixed high pulse width; outputs 7.17kHz pulse during over-current condition. |
| 7 | CF1 | output | Frequency pulse output for current RMS (SEL=0) or voltage RMS (SEL=1) with 38uS fixed high pulse width. |
| 8 | SEL | input | CF1 output select pin with 80kΩ internal pull-down; SEL=0 selects current RMS output, SEL=1 selects voltage RMS output. |
