The planned applications include industrial robots, photovoltaic systems, uninterruptible power supply (UPS) systems, and transformers.
The TC75W71FU offers significant performance improvements over the existing TC75W56FU, particularly in propagation delay. The new device achieves a maximum delay of 45 ns for low-to-high transitions and 30 ns for high-to-low transitions, compared to 550 ns and 250 ns, respectively, for the TC75W56FU. This high-speed response capability ensures that industrial systems can shut down immediately in the event of an overcurrent, significantly improving operational safety.
To facilitate design integration, the TC75W71FU features a full rail-to-rail input/output voltage range, allowing the component to operate effectively from the minimum supply voltage (GND) to the maximum supply voltage (Vcc). Furthermore, the device supports low-voltage operation with a minimum supply voltage of 1.8 V, making it a versatile choice for a wide range of circuit requirements.
Expanding on this information, Toshiba has outlined plans for two additional models in the series, the TC75W72FU and the TC75W73FU, both slated to enter mass production in February 2026. The upcoming TC75W72FU will feature increased hysteresis for improved noise immunity. The TC75W73FU will offer hysteresis and an open-drain output, enabling signal transmission to voltage domains outside the comparator's power supply.
Housed in SOT-505 (SM8) packages, these comparators are suitable for industrial and consumer applications, including household appliances and power supplies. The series is rated for operation between -40 and 125 °C and supports supply voltages from 1.8 V to 5.5 V.
Toshiba will continue to develop comparators that enhance the safety and reliability of industrial equipment, while expanding its product range to meet a wide variety of customer needs.
