General Description
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 tem-
perature thresholds. Available in 5-Pin SOT-23A pack-
ages, these parts are ideal for applications requiring
high integration, small size, low power and low installed
cost.
