Toshiba Unveils High-Speed CMOS Dual Comparator For Industrial Overcurrent Detection
KUALA LUMPUR, Dec 24 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has launched the "TC75W71FU", a CMOS dual comparator featuring high-speed response and a full input/output range (rail to rail), making it well suited for overcurrent detection in industrial equipment.
Modern industrial equipment, including motor drives and power circuits, increasingly operates with large currents, raising the risk of sudden overcurrent that can damage equipment, halt production lines, and compromise safety.
As efficiency requirements rise and product designs become more compact, circuit tolerance margins have narrowed, increasing the need for faster and more precise overcurrent detection.
The new product offers a faster propagation delay than the current TC75W56FU, with a maximum of 45 nanoseconds (ns) for low-to-high transitions and 30 ns for high-to-low transitions. This enables immediate equipment shutdown in overcurrent, enhancing operational safety.
The input/output voltage range supports the full range—operation from minimum (GND) to maximum (Vcc) supply voltage—making design easier. The minimum operating supply voltage, 1.8 volts, supports low-voltage operation.
According to Toshiba in a statement, its push-pull output enables fast signal rise and fall times without requiring an external pull-up resistor, ensuring stable voltage levels.
In addition to TC75W71FU, TC75W72FU, which features added hysteresis for enhanced noise immunity, and TC75W73FU, which offers hysteresis and an open-drain output capable of sending signals to voltage domains different from the comparator’s supply, are scheduled to start mass production in February 2026.
Toshiba will continue to develop comparators that contribute to improved safety and reliability of industrial equipment and to expand the product lineup to meet a wide range of customer needs.
