Frequently Asked Questions
What supply voltage range does the TSX393IPT support, and how does it affect system design?
The TSX393IPT operates from 1.8 V to 16 V single supply, giving designers flexibility to run it directly from a 3.3 V MCU rail, a 5 V logic bus, or a 12 V industrial supply without external regulation. This 1.8 V lower limit is especially valuable in battery-powered designs where cell voltage sags over discharge cycles.
How does the 5 µA quiescent current of TSX393IPT compare to standard comparators in always-on sensing applications?
At only 5 µA supply current per comparator, the TSX393IPT consumes roughly 10 to 100 times less power than general-purpose comparators such as LM393, which draws around 400 µA. In a coin-cell IoT node running continuously, this difference translates to months of additional battery life, making TSX393IPT a strong choice for always-on threshold detection.
Which STMicroelectronics package options and temperature grades are available for the TSX393IPT?
TSX393IPT comes in an 8-pin SO-8 (SOIC) package with an industrial temperature grade of -40°C to +125°C. The SO-8 footprint measures approximately 5 mm × 4 mm, making it suitable for compact PCB layouts. ST also offers equivalent devices in other small-outline variants for different board-area constraints.
Can TSX393IPT drive a 3.3 V logic input directly with its open-drain output?
Yes. Because the output is open-drain, a pull-up resistor of typically 10 kΩ to the 3.3 V rail sets the logic high level, making it fully compatible with 3.3 V MCU GPIO inputs. The output can sink up to 15 mA, so values from 1 kΩ to 100 kΩ are practical depending on speed and power trade-offs.
