GX709 Programmable Resistor Temperature Switch

The GX709 is a fully integrated, programmable resistor temperature switch designed for precise temperature monitoring. It offers a configurable temperature threshold set by a single external resistor, low static current, and selectable hysteresis. The device features an open-drain, active-low output and operates within a wide voltage range. Its small form factor in SOT23 or DFN6L packages makes it suitable for various electronic systems.
