TLP7930(D4-TP1 Übersicht
An isolated delta-sigma modulator is an isolation component that transfers a measured analog quantity across an electrically isolated boundary using optical coupling and digital modulation. Its output is not a conventional parallel ADC result; instead, the modulator produces a one-bit stream whose density represents the input voltage. The receiving system reconstructs or filters that stream digitally. This architecture places signal conditioning and noise rejection close to the isolated sensing circuit while avoiding a direct conductive path between the measured domain and the control domain.
The TLP7930 family uses a second-order sigma-delta modulation technique and a 1-bit output, according to the verified Toshiba-related datasheet descriptions. The listed isolation rating is 5000 Vrms. The product pages classify it as an isolation amplifier or optically isolated delta-sigma modulator and identify a digital output. The exact input range, bandwidth, supply limits, propagation timing, and pin-level electrical limits were not included in the provided verified data, so those values remain marked as data needed rather than being inferred.
The component is useful in inverter control, motor phase-current monitoring, isolated voltage measurement, power-factor conversion, and other systems where a high-side or floating-domain signal must reach a controller without sharing ground. The optical barrier supports galvanic separation, while the digital output can be processed by an MCU, DSP, FPGA, or dedicated sigma-delta input stage. Designers should verify the complete datasheet, recommended external components, filter requirements, timing budget, and isolation-rated PCB layout before production release.
Typical implementation places the TLP7930 between a scaled sensor or shunt signal and a digital controller. The analog input is filtered according to the device guidance, while the isolated one-bit output is routed to the controller or an external digital filter. This page combines verified manufacturer and distributor facts with clearly identified missing-data markers rather than presenting unverified electrical claims as specifications.

Typische Anwendungen
TLP7930(D4-TP1 ist geeignet für 6 Anwendungs: Motor Phase-Current Sensing, Inverter Current Sensing, Isolated Voltage Sensing, Power-Conversion Feedback, Industrial Current Monitoring, Isolated Sensor Interface.
Motor Phase-Current Sensing
The Toshiba TLP7930(D4-TP1 is well suited to motor phase-current monitoring because the verified Toshiba product page identifies motor phase-current sensing as an application. Its 1-bit second-order sigma-delta output transfers the analog sensing signal across an optical isolation barrier at a listed 5000 Vrms. Place the device where the shunt or current-sensor output must remain electrically separated from the controller ground, then filter the digital stream in the MCU or DSP. Verify the input range, bandwidth, timing, and external-filter requirements from the complete manufacturer datasheet before production.
Empfohlen
Inverter Current Sensing
Use the TLP7930(D4-TP1 when an inverter measurement node must be isolated from the low-voltage control system. The verified listing describes the device as an isolation amplifier and isolated delta-sigma modulator with a digital output, while the Toshiba page identifies inverter current sensing. Its optically coupled signal path supports a floating measurement domain, and the one-bit stream can be decimated digitally after capture. The design should budget for input filtering, isolation clearances, controller timing, and any output reconstruction filter specified by Toshiba.
Empfohlen
Isolated Voltage Sensing
The TLP7930(D4-TP1 can support isolated voltage sensing when the measured voltage must be transferred across a high-side or floating barrier. Its analog input is converted into a 1-bit second-order sigma-delta stream, allowing the receiving controller to perform digital filtering rather than directly measuring a high-voltage node. The verified data does not provide the input range or recommended scaling network, so those values must come from the Toshiba datasheet. Confirm that the divider, input filtering, isolation layout, and controller acquisition bandwidth satisfy the final accuracy and safety requirements.
Empfohlen
Power-Conversion Feedback
The optically isolated sigma-delta architecture of the TLP7930(D4-TP1 is applicable to power-conversion feedback loops where switching nodes and control circuitry require galvanic separation. The verified product classification places it among isolation amplifiers and isolated delta-sigma modulators, and the listed 5000 Vrms rating supports high-side sensing use cases. Use the digital output as a feedback representation and filter it in the controller, while observing the manufacturer’s recommended input and output implementation. The tradeoff is added digital reconstruction and timing work compared with using a direct analog isolation path.
Empfohlen
Industrial Current Monitoring
The TLP7930(D4-TP1 can be used in industrial equipment that measures current across a high-side bus, motor winding, or isolated sensor domain. The device’s optical coupling keeps the measured signal separated from the controller, while the 1-bit stream provides a digital interface suitable for embedded processing. The verified sources support the isolation and motor/inverter sensing use cases but do not provide CMRR, input impedance, or temperature limits. Engineers should validate those parameters against the datasheet, test the complete isolation path, and maintain the required creepage and clearance around the barrier.
Empfohlen
Isolated Sensor Interface
TLP7930(D4-TP1 is appropriate when an analog sensor located on a floating power domain must communicate with a digital controller. The second-order sigma-delta modulator converts the sensor voltage into a one-bit stream across optical coupling, and the receiving processor can perform averaging, noise shaping, or decimation. This can simplify the controller-side acquisition path while preserving isolation. The supplied data does not identify the sensor input topology or recommended external components, so the sensor gain, anti-alias filtering, grounding, and calibration strategy must be derived from the official datasheet and application requirements.

- Application-specific positioning (vs. Unspecified isolated sensors)
Designhinweise
Treat the 1-bit output as a timing-sensitive digital stream rather than a conventional logic-level ADC result. Route the output with controlled impedance, keep it away from high-current switching paths, and provide a clean digital return on the receiving side. The verified data does not specify the output rate or logic thresholds, so use the Toshiba timing and recommended filtering information before assigning the stream to a microcontroller peripheral.
Preserve the isolation barrier geometry and follow the manufacturer’s recommended land pattern, creepage, clearance, and copper keepout rules. Place input filtering and any input protection close to the analog pins, and keep the isolation-side return current path compact. Do not place high-voltage switching copper beneath or across the barrier unless the package and safety guidance explicitly permit it.
Do not substitute the TLP7930(D4-TP1,F or TLP7930F naming variants without checking the exact suffix, temperature grade, package marking, and ordering information. The supplied search results establish family-level identity but do not provide a complete cross-reference table for every suffix. Confirm input range, supply rails, timing, isolation test conditions, and environmental ratings from the current Toshiba datasheet before releasing a BOM change.
Compliance-Informationen
The verified Toshiba document note says to contact Toshiba sales for environmental information such as RoHS compatibility. A distributor listing reports a Pb-F marking, but this does not by itself establish full RoHS, REACH, halogen-free, or conflict-minerals status.
