TLP7930(D4 概述
An optically isolated amplifier transfers measurement information across a galvanic barrier by converting an analog input into a modulated digital representation, passing it through an optical path, and reconstructing the signal on the isolated output side. This category sits between analog signal conditioning, data conversion, and industrial isolation components. It is useful where a high-voltage or electrically noisy domain must be separated from a controller, while preserving a digital interface suitable for a microcontroller or DSP.
The verified Toshiba product page identifies the TLP7930 as a digital-output isolation amplifier with 5000 Vrms isolation, while distributor results describe the family as an isolated module, a 16-bit serial interface in one listing, and a DIP-8 gull-wing or tape-and-reel package in another. The available data does not establish input bandwidth, input range, output logic levels, propagation delay, CMTI, supply requirements, or exact pin functions; those values must be confirmed from the manufacturer datasheet before design release.
The device is appropriate for motor phase-current sensing, inverter current and voltage sensing, isolated measurement channels, and industrial power-conversion systems where a controller must remain electrically separated from the sensed power stage. Compared with ordinary analog isolation amplifiers, the verified digital-output architecture can simplify receiver-side signal handling, provided the host interface timing and voltage levels match.
PCB design should preserve the isolation creepage and clearance required by the application, route the isolated and non-isolated grounds separately, and treat the optical barrier as a safety or functional-isolation boundary rather than a power path. The 5000 Vrms rating is a verified headline rating, but it does not replace the complete datasheet requirements for insulation, surge, layout, and working voltage.
This page consolidates distributor pricing, verified product classification, package information, source URLs, and engineering-oriented selection guidance. It does not infer electrical parameters that were not present in the supplied data; engineers should use the Toshiba datasheet for final timing, accuracy, safety, and layout decisions.

典型应用
TLP7930(D4 适用于 6 应用s: Motor Phase-Current Sensing, Inverter Current Sensing, Inverter Voltage Sensing, Isolated Measurement in Power Conversion, Industrial Current Monitoring, Isolated Sensor Interface.
Motor Phase-Current Sensing
The TLP7930(D4 is suitable for motor phase-current measurement because Toshiba identifies motor phase-current sensing as an application and describes the device as a 5000 Vrms optically isolated digital-output amplifier. Place the sensing front end on the power-stage side and route the resulting digital signal across the isolation barrier to the controller. The verified one-bit, second-order sigma-delta architecture supports digital transfer of the measured quantity, but input range, bandwidth, accuracy, and timing must be selected from the manufacturer datasheet.
推荐
Inverter Current Sensing
For inverter current sensing, the TLP7930(D4 provides an optically isolated digital measurement path between a high-voltage or high-current power section and the control electronics. Its verified 5000 Vrms isolation rating is useful where the measurement domain must be electrically separated from the controller. The designer must still verify input limits, isolation working voltage, propagation behavior, and output timing against the Toshiba datasheet before fixing the analog front end.
推荐
Inverter Voltage Sensing
The TLP7930(D4 can support inverter voltage-sensing channels when the controller must receive an isolated representation of a power-stage voltage. The device's optical coupling and verified 5000 Vrms isolation specification help separate the measurement domain from the logic side. Input conditioning and filtering remain application-specific; use the Toshiba datasheet to establish the permitted input range, signal bandwidth, isolation rating conditions, and digital output behavior.
推荐
Isolated Measurement in Power Conversion
TLP7930(D4 is applicable to isolated measurement channels in power-conversion equipment where analog information must cross a high-potential barrier before digital processing. Its one-bit, second-order sigma-delta conversion path can simplify the receiver-side architecture, while optical coupling provides the galvanic separation identified in the verified Toshiba listing. Layout should maintain the datasheet-required creepage and clearance, isolate return currents, and provide local decoupling on both sides of the device.
推荐
Industrial Current Monitoring
The TLP7930(D4 can be used for industrial current-monitoring subsystems that require a measurement signal to cross from a noisy power environment into a controller. The verified digital output avoids presenting an analog signal directly across the isolation boundary, while the 5000 Vrms specification supports a high-isolation interface. The design must validate input excitation, sensor conversion, filtering, timing, and safety-related creepage and clearance before production use.
推荐
Isolated Sensor Interface
TLP7930(D4 is suitable for an isolated sensor interface when a transducer is referenced to a hazardous or electrically noisy node. The optically coupled device transfers a sigma-delta representation rather than requiring a long analog trace across the barrier. Use the exact manufacturer pin definitions to determine input and output-side supplies, and configure the receiver firmware for the verified serial-interface description and the timing limits found in the datasheet.

设计说明
Treat the isolation boundary as a physical layout constraint. The verified 5000 Vrms isolation rating does not by itself define final creepage, clearance, or working voltage, so use the Toshiba datasheet and applicable safety requirements to set board spacing. Keep the isolated-side and logic-side ground returns separate, avoid copper routing across the barrier except where explicitly allowed, and place input, output, and supply components close to their associated pins.
The verified distributor description identifies a one-bit, second-order sigma-delta data path, so the receiving circuit and firmware must be designed for the resulting digital bitstream rather than assuming a conventional analog output. Confirm serial framing, clocking, output logic levels, data validity, and timing from the manufacturer datasheet. PCB traces should be short and referenced to the appropriate isolated or logic ground, with supply bypass placed close to the device.
Do not treat TLP7930(D4, TLP7930(D4,F, and TLP7930(D4-TP1,F as interchangeable without checking the ordering information. The supplied results distinguish bulk-related and tape-and-reel catalog listings, but do not provide a complete suffix comparison. Also do not infer safety compliance from the isolation voltage: RoHS status requires contacting Toshiba, and REACH, lead-free, halogen-free, and conflict-minerals information was not supplied.
合规信息
The Toshiba documentation note instructs users to contact a Toshiba sales representative for details about environmental information such as RoHS compatibility. No definitive compliance status was supplied for the other fields.
