What are the key features of TSM109AID?
- Dual independent comparators with 1.3 µs propagation delay for responsive threshold detection
- Wide 3 V to 28 V single-supply range covering automotive, industrial, and 5 V logic applications
- Open-collector outputs allow wired-OR configurations and direct drive of logic levels from 3 V to 28 V
What is TSM109AID used for?
TSM109AID is commonly used in voltage monitoring circuits, window comparator designs, and over-voltage or under-voltage detection in power management systems. Its wide 3 V to 28 V supply range and dual-channel architecture make it ideal for industrial control panels, battery chargers, and motor driver protection circuits where multiple threshold comparisons are needed. It is also suitable for level-shifting and zero-crossing detection in signal conditioning applications.

Frequently Asked Questions
What supply voltage range does TSM109AID support, and how does it compare to LM393 in industrial designs?
TSM109AID operates from 3 V to 28 V single supply, which is identical to the classic LM393 operating range. This compatibility allows drop-in replacement in existing industrial designs while benefiting from STMicroelectronics manufacturing consistency and a 1.3 µs propagation delay that matches or improves response time versus many legacy comparator variants.
How can TSM109AID be used in a window comparator circuit for battery over-voltage protection?
By connecting both channels of TSM109AID to a resistor divider network, one comparator monitors the upper threshold (e.g., 4.2 V for Li-ion) and the other monitors the lower threshold (e.g., 2.7 V). The open-collector outputs can be wired-OR to assert a single fault signal within 1.3 µs of the voltage crossing either limit, providing fast battery protection in 3 V to 28 V systems.
What is the input offset voltage of TSM109AID and how does it affect threshold accuracy?
TSM109AID has a maximum input offset voltage of 9000 µV (9 mV). In precision threshold detection applications this offset should be accounted for by adding hysteresis of at least 20 mV to prevent chatter around the threshold, or by trimming the reference voltage to compensate for the worst-case 9 mV error at the comparator input.
What PCB package does TSM109AID use and how many pins does it have?
TSM109AID comes in an 8-pin Small Outline (SO-8) surface-mount package with a body size of approximately 4.9 mm × 3.9 mm and a 1.27 mm pin pitch. This standard footprint is compatible with a wide range of PCB design rules and allows easy sourcing from multiple distributors, with a 0.25 µA typical bias current per input minimizing loading on resistor divider reference networks.
