Connect an external capacitor (typ. 10 nF) to GND; forms an RC low-pass with the 1.7 kΩ internal filter resistance to adjust output bandwidth and noise. |-| 7 | VIOUT | output | Analog output signal. Voltage is proportional to the sensed primary current with sensitivity ~40 mV/A for the ±50 A / 5 V version. Drive resistive load ≥4.7 kΩ; output capacitance ≤10 nF. |-| 8 | VCC | power_in | Device power supply terminal. Nominal 5 V ±0.5 V for the '5' supply variant (absolute max 6 V). Bypass with 0.1 µF to GND close to the pin. |+| 1 | IP+ | passive | Terminal for current being sensed (positive side of primary conductor). Internally fused/tied to pin 2 through the 0.8 mΩ primary copper path. Electrically isolated from pins 5-8 by 3000 VRMS reinforced isolation. |+| 2 | IP+ | passive | Terminal for current being sensed (positive side of primary conductor). Internally connected to pin 1 through the primary copper conduction path. Typically tied to pin 1 externally to carry the sensed current. |+| 3 | IP- | passive | Terminal for current being sensed (return side of primary conductor). Internally connected to pin 4 through the primary copper path. Current flowing pin 1/2 → pin 3/4 produces a positive-slope output. |+| 4 | IP- | passive | Terminal for current being sensed (return side of primary conductor). Internally tied to pin 3 through the primary copper path. Typically tied to pin 3 externally. |+| 5 | GND | power_in | Signal ground terminal for the sensor / low-voltage side of the isolation barrier.

Together with the internal 1.7 kΩ filter resistor (RF(int)), CF forms an RC low-pass on the output signal path. Default −3 dB bandwidth is 120 kHz with CF = 0. |+| 7 | VIOUT | output | Analog output signal. Ratiometric to VCC; for the AB5 variant (VIOUT proportional to VCC), zero-current output ≈ VCC/2 with a slope of 40 mV/A (typical) over the ±50 A range. Drives loads down to RL = 4.7 kΩ; VOH ≥ VCC − 0.2 V, VOL ≤ 0.2 V. |+| 8 | VCC | power_in | Device power supply terminal. Nominal 5 V ± 0.5 V for the AB5 variant (3.3 V options exist as AB3 variants). Typical supply current ICC = 10 mA (14 mA max). Bypass locally with 0.1 µF to GND. |  ## Key specifications @@ -29,7 +29,16 @@ CH70150AB5PR from COSEMITECH, in a SOP-8.
