Solar Inverter DC Bus Sensing
Solar inverters have DC bus voltages up to 1000V, requiring precise measurement for MPPT and safety protection. The TPS4141-Q1 scales the DC bus voltage down with better accuracy than discrete resistor dividers, thanks to matched resistors and a PGA. The integrated high-voltage switch can disconnect the sense input during power-down, improving safety. The four gain settings provide flexibility for different inverter architectures. The SOIC-11 package fits compact inverter control boards, and low input leakage ensures high measurement accuracy.
Recommended
Industrial Motor Drive Voltage Monitoring
In industrial motor drives, the DC bus voltage must be monitored for overvoltage and undervoltage protection. The TPS4141-Q1 handles voltages up to 1200V, covering common 400V and 690V drive systems. Its programmable-gain amplifier offers four divider ratios, enabling the same device to be used across multiple drive ratings. The bi-directional measurement capability supports negative bus monitoring in regenerative drives. The device's high CMRR and low noise reduce false trips, and its small SOIC-11 footprint saves board space.
Recommended
Traction Inverter Voltage Feedback
Traction inverters in electric vehicles require fast and accurate DC bus voltage feedback. The TPS4141-Q1 provides the necessary high-voltage scaling with a programmable gain amplifier. The integrated switch disconnects the sense line during fault conditions. The AEC-Q100 qualification and wide temperature range ensure reliable operation under thermal stress. The four divider ratios allow tuning for 400V, 800V, or higher bus voltages. The device's low error contributes to accurate torque control, prolonging motor life.
Recommended
Data Center Power Monitoring
In data center power distribution, monitoring high-voltage DC buses in new architectures requires precision. The TPS4141-Q1's matched resistor divider and PGA provide stable scaling for 300-800V rails. The bi-directional capability supports both positive and negative bus segments, useful in battery-backed designs. The integrated high-voltage switch enhances safety by isolating the sense pin when not needed. The small SOIC-11 allows high-density monitoring boards, and the device's configurable ratios reduce BOM proliferation across different voltage levels.

High-Voltage Test Equipment
Precision high-voltage test equipment needs accurate voltage conversion. The TPS4141-Q1's integrated matched resistors and programmable gain provide excellent ratio accuracy, reducing calibration requirements. The 1200V capability covers a wide range of instruments. The high-voltage switch can be used to disconnect the input during auto-ranging or safety interlock. The device supports external reference for accurate bi-directional measurements. Its SOIC-11 package fits standard test probes, and the four divider ratios allow a single design to cover multiple ranges.

Design Notes
For 1200V operation, maintain sufficient spacing between the high-voltage pin and low-voltage components. Follow IPC-2221 for creepage distances. Place the REF capacitor close to the REF pin for stable reference. Use a minimum isolation barrier of 6mm for 1200V DC per common safety standards.
Pins 9 and 10 have a known discrepancy between NC and HV on the EVM; verify with the datasheet before layout. Also ensure the external reference is grounded to HVGND for bi-directional measurement. Missing this connection can cause abnormal readings.
The device dissipates little power, but ensure the SOIC-11 package has adequate copper pour for heat spreading. At high ambient temperatures, verify the junction temperature stays within datasheet limits. Keep the high-voltage traces away from the REF pin to reduce thermal and electrical interference.
