TLP7930(F - 5000 Vrms Digital Isolation Amplifier | Toshiba
MPN： TLP7930(F ✓ 啟用中TLP7930(F 概覽
An isolation amplifier is an analog-front-end component that transfers measurement information across a high-voltage barrier while electrically separating the input side from the output side. The TLP7930 combines an analog input stage, sigma-delta modulation, optical coupling, and digital recovery, placing it within the hierarchy of optocouplers, isolation amplifiers, isolated delta-sigma modulators, interface ICs, and semiconductors. This makes it suitable for systems that require reinforced measurement isolation rather than only signal-level coupling.
The verified product data identifies a digital output, 1-bit second-order sigma-delta modulation, 5000 Vrms isolation, and an 8-pin DIP package. The 1-bit stream is intended to be filtered or decoded by a downstream digital system. Because the source material supplied here does not include the complete electrical timing table, input range, supply requirements, propagation characteristics, accuracy, or temperature limits, those values remain unspecified rather than being inferred.
TLP7930(F is associated with motor phase current sensing and inverter current sensing, where a measurement signal may need to cross from a high-voltage or high-noise power domain into a control system. The optical isolation barrier helps prevent high-side ground currents and common-mode transients from coupling into the controller. The DIP-8 outline also supports through-hole assembly and prototyping, although the exact mechanical drawing should be checked against the manufacturer documentation before layout work begins.
Designers should treat the isolation rating as a safety-related selection item, not merely a signal-processing parameter. The input-side and output-side ground domains must be laid out and connected as separate circuit regions, and the datasheet's creepage, clearance, capacitor, supply, and decoupling recommendations should control the final isolation barrier. The verified manufacturer search result also advises using the Toshiba standard type number for safety-standard applications.
Typical applications include isolated motor phase-current measurement, inverter current measurement, industrial inverter control, power-factor monitoring, and isolated sensing in power-conversion equipment. For new designs, engineers should confirm the exact suffix, package variant, safety approvals, environmental qualifications, and electrical limits using the Toshiba TLP7930 datasheet.

典型應用
TLP7930(F 適用於 6 應用s: Motor Phase Current Sensing, Inverter Current Sensing, Industrial Motor Drive, Power-Factor Monitoring, Isolated Sensor Interface, Isolated Voltage Sensing.
Motor Phase Current Sensing
The Toshiba TLP7930(F fits isolated motor phase-current measurement because it converts an analog sensing signal into a 1-bit, second-order sigma-delta stream while providing 5000 Vrms optical isolation. Place the input-side network near the phase-current measurement element and route the recovered digital data toward the inverter controller. The isolation path helps keep high-side transients from coupling directly into the logic domain, while the digital stream can be filtered according to the control system’s timing and noise requirements. The verified material confirms this application, but final bandwidth, accuracy, input-range, and timing checks must come from the manufacturer datasheet.
推薦
Inverter Current Sensing
TLP7930(F is explicitly positioned by Toshiba for inverter current sensing. Its analog input is converted to a digital sigma-delta representation across an optically coupled barrier rated at 5000 Vrms, allowing a controller to monitor current without sharing the isolated-side ground. In a power converter, the sensing amplifier should be placed close to the current-sense element to reduce pickup, while the output-side interface must match the controller’s filtering and sampling expectations. Verify the device’s actual input range and delay before selecting compensation and protection thresholds.
推薦
Industrial Motor Drive
The TLP7930(F is useful in industrial motor-drive electronics where a phase-current measurement must cross from a switching power stage into a control system. Its digital sigma-delta output can simplify isolation of the analog measurement path and provide a serial representation for filtering or decoding. The designer should maintain separate input-side and output-side ground regions, keep high-current switching loops compact, and follow the manufacturer’s isolation-layout guidance. Because the verified data does not specify accuracy, bandwidth, or temperature limits, those values must be validated before production release.
推薦
Power-Factor Monitoring
TLP7930(F can support isolated measurement in power-factor and power-quality systems when an analog current or voltage-related signal must be transferred into a supervisory controller. The optically coupled sigma-delta path avoids a galvanic connection between the power domain and the monitoring electronics. A practical implementation should minimize input-node capacitance, use a suitable reconstruction or filtering stage after the bitstream, and verify that the measurement bandwidth meets the control or reporting objective. The verified source confirms isolation-amplifier and inverter-sensing use, but not a finished power-factor application circuit.
推薦
Isolated Sensor Interface
The TLP7930(F is suitable for an isolated sensor interface when the measured quantity is analog and the downstream system needs a digital representation separated by an optical barrier. Place the sensor-side input network at the isolated-domain reference and connect the digital output to a controller or decoder. The 1-bit sigma-delta format can support digital filtering, but the actual signal bandwidth and reconstruction performance depend on the complete manufacturer electrical specifications. Engineers must also account for isolation capacitance, grounding, PCB creepage, and the required safety category.
推薦
Isolated Voltage Sensing
TLP7930(F can be used as the isolation element in an analog voltage-measurement chain where the sensed voltage is associated with a power-conversion stage. The device’s analog input, sigma-delta modulation, and optical coupling provide a route from the measured node to a digital controller without a direct conductive output connection. The input conditioning network must be designed around the unavailable input-range and accuracy data, and the controller must reconstruct the signal from the 1-bit stream. Verify the working voltage, package spacing, and isolation standard required by the end product.

設計說明
Maintain separate input-side and output-side ground domains, and route the isolation boundary so copper, vias, test points, and protective components do not unintentionally bridge it. The TLP7930(F is an isolation amplifier rather than a general-purpose logic isolator, so the input-conditioning network and digital reconstruction circuitry must follow the manufacturer’s recommended layout. Verify creepage and clearance against the final working voltage and applicable safety requirement.
The 1-bit sigma-delta stream carries the measurement information across the optical path, so the receiver-side filtering and decoding design is part of the measurement accuracy. Keep the input node compact and control parasitic capacitance, especially in motor-drive systems where switching transitions can couple into sensitive analog nodes. Use the manufacturer timing and frequency-response limits to set digital filtering and sampling rather than selecting filter values from general guidance.
Do not treat the 5000 Vrms isolation figure as a complete safety approval or assume every TLP7930 suffix has identical pinout and electrical limits. The verified data contains multiple ordering-code variants but does not provide their complete comparison tables. Before substitution or production release, compare the exact suffix, package drawing, input range, supply voltage, propagation timing, creepage, clearance, qualification, and environmental documents.
