HCPL-2212-500E - 5MBd Logic Gate Optocoupler | Broadcom
MPN： HCPL-2212-500E ✓ 啟用中HCPL-2212-500E 概覽
An optocoupler (also called optoisolator) is a semiconductor device that transfers electrical signals between two isolated circuits using light. The HCPL-2212-500E belongs to the logic-output optoisolator family, where the photodetector stage is replaced by a logic gate. This places it in the hierarchy: optocoupler -> galvanic isolator -> signal isolator -> interface IC. Logic-output optoisolators are widely used for SPI, RS-232, RS-485, and inter-PECL signaling across an isolation barrier.
Key features include a 5 MBd guaranteed data rate, a very high common-mode transient immunity (CMTI) of 10 kV/µs at 1000 V common-mode voltage, and a wide supply range of 4.5 V to 20 V on VCC. The internal Faraday shield guarantees superior CMR performance. The totem-pole output eliminates the need for a pull-up resistor on the output side, simplifying PCB layout.
Typical applications include isolated data communication in industrial motor drives, programmable logic controller (PLC) I/O isolation, switching power supply feedback loops, isolated gate drive interfaces for power MOSFETs and IGBTs, and digital logic level shifting across high-voltage barriers. The 3750 Vrms isolation rating qualifies it for reinforced isolation per common safety standards.
When designing with this device, ensure that the input LED forward current is set within the 1.6 mA nominal operating range using an appropriate external resistor. The internal CMOS output can source/sink directly, but trace length and capacitive loading should be minimized to preserve the 5 MBd data rate. A 0.1 µF VCC bypass capacitor placed close to pin 8 is recommended for stable operation.

典型應用
HCPL-2212-500E 適用於 6 應用s: Isolated SPI / UART Communication, Industrial Motor Drive Gate Drive Isolation, Switching Power Supply Feedback Loop, PLC Digital Input/Output Isolation, Medical Equipment Patient Isolation, Solar Inverter String Monitoring.
Isolated SPI / UART Communication
The HCPL-2212-500E provides robust galvanic isolation for SPI and UART signals between a low-voltage microcontroller and high-voltage industrial peripherals. Its 5 MBd data rate comfortably supports SPI clock frequencies up to 5 MHz, while the 3750 Vrms isolation protects the controller from fault voltages on the field side. The totem-pole push-pull output eliminates the need for an external pull-up resistor, simplifying PCB routing.

Industrial Motor Drive Gate Drive Isolation
In variable-frequency motor drives, the HCPL-2212-500E isolates low-voltage PWM control signals from high-voltage IGBT/MOSFET gate drivers. Its 10 kV/µs common-mode transient immunity (CMTI) at 1000 V common-mode voltage prevents false triggering during the high dV/dt switching events that occur in 3-phase inverter bridges. The totem-pole output directly drives gate driver IC inputs without external buffering.
推薦
Switching Power Supply Feedback Loop
In isolated AC-DC and DC-DC converters, the HCPL-2212-500E closes the primary-to-secondary feedback loop while maintaining 3750 Vrms isolation. The 5 MBd data rate is more than sufficient for typical PWM feedback duty-cycle encoding, and the totem-pole output interfaces directly with primary-side PWM controller error amplifier inputs. The wide 4.5 V to 20 V VCC range supports both 5 V and 15 V controller rails.
推薦
PLC Digital Input/Output Isolation
Programmable Logic Controllers (PLCs) require reinforced isolation between field wiring (24V/120V/240V) and the backplane logic. The HCPL-2212-500E's 3750 Vrms isolation rating and 10 kV/µs CMTI meet IEC 61131-2 requirements for industrial control digital I/O. The push-pull output directly interfaces with 5V or 24V PLC backplane logic without additional buffering.
推薦
Medical Equipment Patient Isolation
In patient-connected medical electronics such as patient monitors, infusion devices, and ECG systems, the HCPL-2212-500E provides the reinforced 3750 Vrms isolation barrier required between the patient side and operator/line side. The 5 MBd data rate supports standard medical communication buses, while the totem-pole CMOS output interfaces with low-voltage signal processing ASICs. The internal Faraday shield prevents ESD-induced false triggering in clinical environments.
推薦
Solar Inverter String Monitoring
Solar photovoltaic string monitoring and rapid-shutdown systems use the HCPL-2212-500E to transmit control and telemetry signals across the DC bus isolation barrier. The 10 kV/µs CMTI ensures reliable communication despite the high dV/dt switching transients present in MPPT converters. The wide -40 °C to +85 °C operating range supports outdoor inverter installations.

設計說明
The HCPL-2212-500E requires a stable 4.5 V to 20 V supply on pin 8 (VCC). A 0.1 µF ceramic bypass capacitor placed within 5 mm of pin 8 is essential to suppress high-frequency noise. For noisy industrial environments, add a 10 µF electrolytic bulk capacitor in parallel. The output side also requires a separate V_O supply (pin 5) at the same voltage range. Ensure that input LED forward current is set to 1.6 mA nominal using an external series resistor (R = (VCC - V_F)/I_F, with V_F ≈ 1.5 V typical).
Do not exceed the maximum LED forward current of 20 mA or the maximum reverse voltage of 5 V. Always connect pin 7 (enable) to VCC for normal operation; leaving it floating causes the output to enter a high-impedance state. The totem-pole output has limited drive current (typically 13 mA sink/source) - if driving highly capacitive loads or long cables, add an external buffer. Trace length on the output side should be kept below 50 mm to preserve the 5 MBd data rate.
The HCPL-2212-500E operates from -40 °C to +85 °C ambient with no heatsink required at typical LED forward currents. Internal power dissipation is dominated by the LED (approximately 4 mW at 1.6 mA) plus CMOS output stage (approximately 10 mW at 5 V VCC and 5 MHz switching). Total package dissipation is well below 100 mW, so no thermal management is needed beyond normal PCB layout practices.
