What are the key features of TS393IDT?
- Dual open-drain comparator with 2.5 µs propagation delay enabling fast threshold detection across 3 V to 15 V supply voltages
- Ultra-low bias current of 0.6 nA maximizing input impedance for high-resistance sensor interfaces
- Compact 8-pin SOIC (JESD-30 R-PDSO-G8) package with negative supply limit of -18 V for split-rail operation
What is TS393IDT used for?
The TS393IDT is well-suited for voltage threshold detection in battery management systems, where its wide 3 V to 15 V supply range and open-drain outputs allow direct connection to resistor-pull-up wired-OR logic without additional buffering. Its 2.5 µs response time and 0.6 nA bias current make it a reliable choice for zero-crossing detectors and window comparators in industrial analog front-ends. The dual-channel design in an 8-pin SOIC package minimizes board space in portable instruments, power supplies, and automotive sensor conditioning modules.

Frequently Asked Questions
How fast does the TS393IDT respond to an input threshold crossing, and what limits its speed in practice?
The TS393IDT has a propagation delay of 2.5 µs under standard test conditions, which is sufficient for most slow signal conditioning and battery monitoring applications. Speed in practice is also limited by the external pull-up resistor tied to the open-drain output—a 10 kΩ pull-up with typical PCB capacitance adds RC delay on top of the 2.5 µs internal delay.
Which supply configurations does the TS393IDT support for split-rail analog front-end designs?
The TS393IDT supports single-supply operation from 3 V to 15 V and split-supply operation with a negative rail down to -18 V, giving designers flexibility for bipolar analog signal ranges. This range accommodates both 3.3 V embedded systems and ±12 V industrial signal conditioners using the same dual comparator IC in an 8-pin SOIC footprint.
When is the TS393IDT a cost-effective alternative to a precision comparator in a resistive sensor interface?
The TS393IDT's 0.6 nA maximum bias current means it draws negligibly from high-resistance sensors (above 1 MΩ), avoiding the voltage error that higher-bias comparators introduce. For applications where 6500 µV input offset voltage is acceptable—such as simple under-voltage lockout or over-temperature detection at battery monitoring nodes—the TS393IDT provides a lower-cost 8-pin SOIC solution compared to precision rail-to-rail comparators.
