* Notice: Stresses above those listed under "Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

The TC6501/2/3/4 are SOT-23 temperature switches that require no external components and are available with factory-programmed temperature thresholds. A choice of factory-trimmed temperature trip points are also available. Pin-selectable hysteresis of +2 or +10 allows flexibility to the design of the application. These parts typically consume only 17 µA of current and operate over the entire -55 to +135 temperature range, while offering accuracies of ±0.5 (typ).

The TC6501 and TC6503 have an open-drain, activelow output, which targets microcontroller reset control. The TC6502 and TC6504 have a CMOS, active-high output designed to drive the logic level MOSFET that turns on a fan or heater element.

The TC6501/TC6502 are designed for hot temperature monitoring (+35 to +125). These devices assert a logic signal when the temperature goes above the threshold. The TC6503/TC6504 are optimized for cold temperature monitoring (-45 to +15) and assert a logic signal when the temperature goes below the threshold.

The TC6501/2/3/4 are offered with five standard temperature thresholds. Available in 5-Pin SOT-23A packages, these parts are ideal for applications requiring high integration, small size, low power and low installed cost.
