Broadcom Optocoupler Surface Mount 8-Pin, 230mA Input Current, -40°C to 110°C ACNT-H870-500E

Broadcom ACNT-H870-500E is a high-performance surface mount optocoupler designed for precise isolated voltage sensing. It operates with a 2V nominal input range and features a very high 1 GΩ input impedance, making it ideal for electronic power converter applications such as motor drives and renewable energy systems. This device converts DC-link voltage levels scaled by a resistive divider into an isolated differential output voltage via an optical barrier, ensuring electrical isolation and accurate voltage measurement.

The optocoupler utilizes advanced sigma-delta modulation technology, providing excellent accuracy with unity gain of 1V/V and tight gain tolerance of ±0.5% (ACNT-H87B variant). Its low gain drift rate ( - 35 ppm/°C) and minimal offset voltage drift of 21 μV/°C ensure stable output under varying temperatures. The device supports a maximum input current of 230mA and includes an active-high shutdown pin to enable power saving.

Designed for industrial environments, it has a wide operating temperature range of - 40°C to +110°C and offers 15 kV/μs common-mode transient immunity, enhancing robustness against electrical noise. This broad voltage supply range for the output side (3V to 55V) offers flexibility across different system designs.

Physically, the optocoupler comes in a compact, auto-insertable 15-mm stretched SO-8 package suitable for surface mounting on PCBs, promoting easy integration into manufacturing lines. Manufactured in the Philippines, this product complies with RoHS standards ensuring environmental safety.
