CC6920SO-25A 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 + (primary current input). Positive current flows from IP+ (pins 1-2) to IP- (pins 3-4). Pins 1 and 2 are internally tied to form the high-current input node; connect both to the source side of the sensed current. Rated ICON = 40 A continuous, IPEAK = 100 A (3 s). |
| 2 | IP+ | passive | Current sampled + (primary current input, paralleled with pin 1). Positive current flows from IP+ (pins 1-2) to IP- (pins 3-4). Internal copper conductor resistance is 0.9 mΩ typ at 25 °C. |
| 3 | IP- | passive | Current sampled - (primary current output/return). Positive current exits here from IP+ (pins 1-2) to IP- (pins 3-4). Pins 3 and 4 are internally tied; connect both to the load side of the sensed current. |
| 4 | IP- | passive | Current sampled - (primary current output/return, paralleled with pin 3). Positive current exits here from the sensed conductor. |
| 5 | GND | power_in | Signal-side ground return for the Hall sensor secondary circuitry. Reference node for VCC, OUT, and VZCR. Isolated from the primary current path (pins 1-4) by 3500 VRMS. |
| 6 | VZCR | output | Zero-current reference signal output (nominally VCC/2). Provides a matched reference equal to the quiescent OUT voltage so downstream circuitry can subtract offset for ratiometric measurement. Source current ≤ 400 μA, sink current ≤ 3000 μA - reserve ~0.3 mA of headroom in the design. |
| 7 | OUT | output | Analog voltage output proportional to the sensed primary current. Quiescent (IP=0) output is VCC/2 (2.5 V typ at VCC=5 V). For the -25A variant, transfer function is VOUT = VCC/2 + 0.080 × IP(A), giving a guaranteed linear range of 0.5-4.5 V. Minimum load 1.5 kΩ, max load capacitance 1 nF; source ≤ 6 mA, sink ≤ 30 mA. |
| 8 | VCC | power_in | Positive supply input, 4.5-5.5 V (5 V nominal). Absolute maximum 7 V. Typical supply current 20 mA (25 mA max) with OUT unloaded. Bypass locally to GND (pin 5) with a low-ESR ceramic capacitor. |
