SSP1837

Shanghai Siproin Microelectronics · Energy Metering · SOP-8

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.
