TLP7830(D4KWJT4E - Isolated Delta-Sigma Modulator | Toshiba
料号： TLP7830(D4KWJT4E ✓ 量产中TLP7830(D4KWJT4E 概述
An isolated delta-sigma modulator is a signal-conditioning semiconductor that combines analog-to-digital conversion, digital data transmission, and galvanic isolation in one package. The analog input is modulated by the optically isolated modulator and represented as a serial bitstream, allowing a host system to reconstruct the measured signal digitally. The TLP7830 is therefore positioned within the hierarchy of isolation amplifier, isolated ADC, and isolated signal-chain ICs.
Key verified features include 1-bit delta-sigma operation, optical isolation, a digital output, 5000 Vrms isolation, and an SO8L (LF4) package. The 1-bit output format simplifies the interface between the isolated front end and downstream digital processing, while the isolation barrier helps protect host circuitry from high-side voltage potentials. The manufacturer specifically highlights motor phase current sensing and inverter current or voltage sensing as suitable applications.
The device is intended for industrial power-conversion systems where measurement signals cross a high-voltage isolation barrier. In a motor controller or inverter, the isolated modulator can transfer an analog feedback signal to a controller without providing a direct conductive path between the measured power domain and the logic domain. Digital decoding, filtering, and calibration remain part of the downstream signal-processing chain.
Typical system placements include three-phase motor drives, inverter control boards, isolated current-feedback channels, and industrial measurement equipment. Designers should evaluate the complete input, logic, timing, isolation, and filtering specifications against their system requirements before finalizing the PCB layout. The available verified data identifies the functional family and isolation rating but does not provide a complete operating-parameter table or detailed pin map for this ordering code.
This product page consolidates the verified Toshiba product information, distributor listings, package identity, application positioning, and available comparison information. It also distinguishes what is explicitly verified from parameters that require confirmation in the manufacturer datasheet, avoiding unsupported electrical or timing claims.

典型应用
TLP7830(D4KWJT4E 适用于 6 应用s: Motor Phase Current Sensing, Three-Phase Inverter Control, Isolated DC-Link Voltage Sensing, Industrial Motor Controller, Isolated Current Measurement, Power-Supply Feedback Isolation.
Motor Phase Current Sensing
The TLP7830(D4KWJT4E) fits three-phase motor-control feedback because Toshiba explicitly identifies motor phase current sensing as an application. Its 1-bit second-order delta-sigma modulator converts the analog measurement into a serial bitstream while optical coupling provides a 5000 Vrms-rated isolation barrier between the power domain and controller logic. The receiving system must decode and filter the stream, and the complete design should verify input range, bandwidth, data rate, and propagation delay because those values were not present in the supplied excerpts.
推荐
Three-Phase Inverter Control
The TLP7830(D4KWJT4E) is suitable for inverter feedback channels where analog power-stage information must reach a digital controller across a high-potential barrier. Its second-order 1-bit delta-sigma architecture produces a high-speed serial output, while the verified 5000 Vrms isolation rating supports robust separation in industrial power electronics. Engineers should budget receiver filtering and decoding resources and confirm that signal bandwidth, logic levels, and timing meet the inverter switching environment before schematic approval.
推荐
Isolated DC-Link Voltage Sensing
The TLP7830(D4KWJT4E) can serve as the isolated signal path for DC-link voltage monitoring when the sensing front end and control system occupy different voltage domains. The analog input is transformed into a 1-bit delta-sigma stream, allowing digital reconstruction after optical isolation. The 5000 Vrms rating is relevant to reinforced separation, but the circuit still requires suitable input conditioning, safety-rated spacing, filtering, and calibration. Verify operating temperature, input limits, and isolation-system standards against the final installation.
推荐
Industrial Motor Controller
For an industrial motor controller, the TLP7830(D4KWJT4E) provides a compact way to transfer analog feedback through an optical isolation barrier and into a digital processing chain. The verified 1-bit second-order delta-sigma format supports high-speed serial communication while the 5000 Vrms isolation separates the measurement side from sensitive control electronics. Its SO8L (LF4) package supports surface-mount assembly. Final qualification should include thermal cycling, noise-immunity, timing, PCB isolation-clearance, and functional-safety reviews where applicable.
推荐
Isolated Current Measurement
The TLP7830(D4KWJT4E) is applicable to isolated current-measurement channels because its manufacturer description lists current sensing and inverter measurement use cases. The modulator accepts an analog signal, optically transfers the measurement information, and presents a serial digital stream to the host. This architecture can reduce the need for a separate isolation amplifier and ADC in the signal path. However, the verified excerpts do not establish full-scale input accuracy, noise performance, bandwidth, or propagation delay, so those specifications must be confirmed in the Toshiba datasheet.
推荐
Power-Supply Feedback Isolation
The TLP7830(D4KWJT4E) can be evaluated for isolated power-supply feedback where a control loop operates across a primary-secondary barrier. The optically coupled 1-bit second-order delta-sigma output provides a digital feedback representation instead of a direct analog connection. The 5000 Vrms isolation rating and compact SO8L package are useful for isolated auxiliary power and monitoring circuits. Designers must confirm the permitted input signal range, loop bandwidth, output timing, and safety creepage requirements, which were not included in the verified search excerpts.

设计说明
Treat the isolation barrier as a high-potential interface rather than an ordinary signal trace. According to Toshiba, the device supports 5000 Vrms isolation, but the applied working voltage, creepage, clearance, pollution degree, and safety standard determine the required PCB spacing. Keep the isolated and logic-side copper regions apart, remove excess board material beneath the barrier where applicable, and verify the final layout against the manufacturer isolation guidance.
The 1-bit second-order delta-sigma output requires a deterministic receiver and filtering strategy. Route the serial signal over a controlled impedance path, keep it away from switching-node copper and high-current inductors, and validate timing at the receiving controller. The supplied data does not state the supported data rate, propagation delay, or input bandwidth, so receiver timing and digital filter bandwidth must be derived from the complete Toshiba datasheet rather than assumed.
Do not substitute an 8-pin isolation IC solely because it uses a similar SOIC footprint. The only supplied comparison candidate is the Toshiba TLP7820, and the available record confirms its 8-SOIC package but does not prove identical pin functions, electrical ratings, or signal timing. Validate every pin, the input range, logic levels, data stream behavior, isolation rating, and acquisition timing against both datasheets before treating the candidate as a drop-in part.
