HT8712R-30A

HTCSEMI · Current Sensors · SOP-8

HT8712R-30A from HTCSEMI, in a SOP-8. 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 IP+ passive Current-sense conductor terminal (fused internally with pin 2) for the current being sampled; isolated from signal pins 5-8 by 2.4 kVRMS minimum.
2 IP+ passive Current-sense conductor terminal (fused internally with pin 1) for the current being sampled; 1.2 mΩ typical primary conductor resistance.
3 IP- passive Current-sense conductor terminal (fused internally with pin 4) for the current being sampled; isolated from signal pins 5-8 by 2.4 kVRMS minimum.
4 IP- passive Current-sense conductor terminal (fused internally with pin 3) for the current being sampled; 1.2 mΩ typical primary conductor resistance.
5 GND power_in Signal ground terminal.
6 FILTER passive Terminal for an external capacitor to ground that sets the bandwidth (1 nF typical, with 1.7 kΩ internal filter resistance).
7 VIOUT output Analog output signal of 66 mV/A typical sensitivity for the 30A variant, VCC/2 at 0 A, with a minimum 4.7 kΩ load and a maximum 10 nF load capacitance.
8 VCC power_in Device power supply terminal, 4.5 to 5.5 V operating (5.0 V typical), 8 V absolute maximum.
