What are the key features of TC1028CEUA?

  • Dual comparator with open-drain outputs for wired-OR or wired-AND bus applications
  • Wide supply voltage range: 1.8 V to 5.5 V for battery-powered designs
  • Rail-to-rail output swing maximizes signal range at low supply voltages
  • Ultra-small SOT-23-6 package minimizes PCB footprint in space-constrained designs
  • Low quiescent current extends battery life in portable applications

What is TC1028CEUA used for?

TC1028CEUA is well-suited for portable and battery-operated electronics where low-power threshold detection is needed. Common applications include window comparators in sensor interfaces, voltage monitoring circuits, and logic-level translation in industrial handheld equipment. Its dual-channel design enables compact implementations of multi-signal detection without additional components.

Frequently Asked Questions

What supply voltage range does TC1028CEUA support, and how does it fit battery-powered designs?

TC1028CEUA operates from 1.8 V to 5.5 V, making it compatible with single-cell lithium-ion batteries and 3.3 V or 5 V regulated rails. Its low quiescent current draw helps extend battery runtime in portable sensing and monitoring applications.

How do the open-drain outputs of TC1028CEUA enable multi-device bus configurations?

The open-drain outputs allow multiple TC1028CEUA devices to share a common signal line, with each output capable of pulling the line low. A single pull-up resistor, typically 10 kohm, enables wired-OR logic, useful in fault detection and alert aggregation circuits with 2-wire interfaces.

When should a designer choose TC1028CEUA over a single comparator IC like MCP6541?

TC1028CEUA provides 2 independent comparator channels in a single 6-pin SOT-23 package, halving the component count versus two discrete MCP6541 devices. This dual integration is preferred when board space is limited and two threshold-detection channels are required within a 5.5 V maximum supply system.
