MICROCHIP TC6501P125VCTTR

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°C or +10°C allows flexibility to the design of the application. These parts typically consume only 17 μA of current and operate over the entire - 55°C to +135°C temperature range, while offering accuracies of ±0.5°C (typ). The TC6501 and TC6503 have an open- drain, active- low 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°C to +125°C). These devices assert a logic signal when the temperature goes above the threshold. The TC6503/TC6504 are optimized for cold temperature monitoring (- 45°C to +15°C) 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.
