HCPL-902J-500E

HCPL-902J-500E is an optically isolated amplifier (analog optocoupler) from the HCPL family. It uses an input LED and an integrated photodetector with on‑chip amplification to convert an input signal on the LED side into a proportional, isolated output signal on the other side. The device provides galvanic isolation between input and output, allowing separate supplies on each side and safe interfacing to high‑voltage or noisy environments. The “500E” suffix indicates reinforced isolation (typically around 5 kV RMS) with Pb‑free packaging. Typical applications include isolated sensing and control loops in motor drives, power converters, and instrumentation where accurate, drift‑resistant signal transfer across a barrier is required. Features include low input offset, good temperature stability, wide operating temperature, and fast response for analog signals. For exact specs (input current range, output range, bandwidth, isolation rating, supply pins), consult the datasheet. Ensure proper decoupling, layout, and safety practices when implementing.

HCPL-902J-500E features (concise):
- Dual-channel optically isolated gate/logic optocoupler (two independent channels)
- High-speed data transfer with TTL/CMOS-compatible outputs
- Open-collector outputs (requires pull-up resistor to logic Vcc)
- Isolation between input and output: 5 kV RMS
- Wide operating temperature range: typically -40°C to 125°C
- Package: 8-pin DIP/SO-8 options
- Low input current with good CTR across temperature
- Suitable for digital signal isolation, microcontroller interfaces, and power/industrial control applications
Note: For exact CTR, propagation delay, CMIT values, and package variants, please refer to the latest datasheet.

8-pin package: DIP-8 (through-hole). It’s also available in SO-8 for surface-mount.

- Pin count: 8 pins (DIP-8/SO-8 package)
- Function: galvanically isolated analog amplifier. It accepts a differential input on the input side and provides an isolated output on the output side (separate power supplies for each side), converting the input signal to a proportional isolated output.

- Manufacturer: Broadcom Inc. (formerly Avago Technologies).
- What kind of company: A global semiconductor company that designs, develops, and sells semiconductor products (and related infrastructure software).

Applications include:
- Isolated analog signal conditioning and amplification for power electronics
- Current and voltage sensing in motor drives, inverters, and DC-DC converters
- Isolated feedback paths to control systems
- Data acquisition/instrumentation in PLCs/SCADA
- Sensor interfacing across galvanic barriers (shunts, current transformers)
- High-voltage measurement equipment
- Renewable energy equipment and battery-management systems
- Medical/industrial instrumentation requiring safety isolation

I can’t reliably list exact equivalents without more specs. HCPL-902J-500E is a Broadcom/Avago optically isolated amplifier; cross-references depend on speed, isolation voltage, channel count, and pinout. Please provide the datasheet or key specs (e.g., VISO, bandwidth, input/output type, package) or allow me to look them up. I’ll then give precise cross-references from major brands (e.g., Broadcom/AV, TI, Vishay, Everlight).
