CC6920BSO-10A from Cross chip, 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 | IP+ | passive | Current-sampled positive input terminal. Tie to pin 2 externally; primary current flows from IP+ (pins 1,2) through the internal ~0.9 mΩ copper conductor to IP- (pins 3,4). Rated up to ±50 A continuous, 100 A peak for 3 s. |
| 2 | IP+ | passive | Current-sampled positive input terminal (second leg of the primary conductor). Electrically common with pin 1; parallel externally to carry the full primary current. 3500 VRMS isolated from pins 5-8. |
| 3 | IP- | passive | Current-sampled negative input terminal. Electrically common with pin 4; the primary current exits here after passing through the internal copper conductor. 3500 VRMS isolated from pins 5-8. |
| 4 | IP- | passive | Current-sampled negative input terminal (second leg). Electrically common with pin 3; parallel externally to carry full primary current. Positive IP is defined as current flowing IP+ → IP-. |
| 5 | GND | power_in | Signal-side ground reference for VCC, VOUT, and VZCR. Isolated from the primary IP+/IP- current path by 3500 VRMS. |
| 6 | VZCR | output | Zero-current reference signal output, typically VCC/2 (1.65 V at VCC=3.3 V). Provides a matched reference for downstream ratiometric ADC or differential-amplifier stages. Source ≤400 µA, sink ≤3000 µA (reserve ~0.3 mA headroom per datasheet note). |
| 7 | OUT | output | Analog voltage output proportional to sensed primary current. For CC6920BSO-10A: VOUT = VCC/2 + 0.132 × IP(A), sensitivity 132 mV/A (127-135 mV/A). Guaranteed accurate/linear over 0.33-2.97 V; rise time ~1 µs, bandwidth 250 kHz. Drive: ≤6 mA source, ≤30 mA sink, load ≥1.5 kΩ, CL ≤1 nF. |
| 8 | VCC | power_in | Positive supply input, 3.0-3.6 V (3.3 V typ), absolute max 7 V. Supply current ~20 mA typ (25 mA max). Decouple with 0.1 µF to GND close to the pin (per typical application circuits). |
