Toshiba extends its TC75W series of CMOS dual comparators for overcurrent detection<\/a><\/strong> in industrial equipment, with the introduction of the TC75W71FU. Featuring high-speed response times and a full input\/output range, the product enables immediate shutdown for enhanced operational safety and supports low-voltage operation. Target applications include industrial robots, photovoltaic systems, uninterruptible power supplies (UPS), and transformers.<\/p>\n\n\n\n

The TC75W71FU delivers significant performance improvements over the existing TC75W56FU, particularly in propagation delay. The new device achieves a maximum delay of 45ns for low-to-high transitions and 30ns for high-to-low transitions compared to 550ns and 250ns, respectively, for the TC75W56FU. This high-speed response capability ensures that industrial systems can shut down immediately in the event of an overcurrent, thereby greatly enhancing operational safety.<\/p>\n\n\n\n

To facilitate easier design integration, the TC75W71FU features a full input\/output voltage range (rail-to-rail), 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 operating supply voltage of 1.8V, making it a versatile choice for a wide range of circuit requirements.<\/p>\n\n\n\n

Expanding on this release, Toshiba has outlined plans for two additional models in the series, the TC75W72FU and the TC75W73FU, both scheduled to enter mass production in February 2026. The upcoming TC75W72FU will feature increased hysteresis to improve noise immunity. The TC75W73FU will offer hysteresis and an open-drain output, enabling signal transmission to voltage domains outside the comparator’s supply.<\/p>\n\n\n\n

Housed in SOT-505 (SM8) packages, these comparators are suitable for industrial and consumer applications, including home appliances and power supplies. The series is rated for operation from -40 to 125\u00b0C and supports supply voltages from 1.8V to 5.5V.<\/p>\n","protected":false},"excerpt":{"rendered":"
