Broadcom ACNT-H87A-500E Optocoupler Surface Mount 8-Pin Voltage Sensor ACNT-H87A-500E

Broadcom ACNT-H87A-500E optocoupler is a surface mount optical isolation amplifier specifically designed for voltage sensing in electronic power converter applications such as motor drives and renewable energy systems. It features an 8-pin configuration housed in a compact 15 mm Stretched SO-8 package, suitable for precise and reliable voltage measurement tasks.

Its high input impedance of 1 GΩ and 0 to 2 V nominal input range make it ideal for interfacing with resistive voltage dividers used in DC-link voltage scaling. The device employs advanced sigma-delta (Σ - Δ) modulation technology to provide a differential output voltage proportional to the input voltage with high accuracy and stability.

The ACNT-H87A-500E supports a maximum input current of 230 mA, operates reliably within a temperature range of -40°C to 125°C, and supports an output supply voltage ranging from 3 V to 55 V. Additional features include low gain drift of -35 ppm/°C, offset voltage drift of 21 μV/°C, and a maximum non-linearity of 0.1% enabling precise voltage sensing performance across varying conditions.

This optocoupler provides an active-high shutdown pin, a bandwidth of 100 kHz, and excellent common-mode transient immunity of 15 kV/μs, ensuring robustness in electrically noisy environments commonly encountered in industrial and renewable energy systems. Its surface mount design allows for easy integration in automated assembly lines.
