MAX6501 MAX6502 1,2 1,2 Name GND 3 3 HYST 4 4 VCC 5 - TOVER - 5 TOVER Description Ground.

Ground both pins together close to the chip.

Pin 2 provides the lowest thermal resistance to the die.

Hysteresis Input.

Connect HYST to GND for +2°C hysteresis, or connect to VCC for +10°C hysteresis.

MAX6501, MAX6502 Ultra Small Temperature Switch with Pin Selectable Hysteresis The MAX6501 and MAX6502 are SOT-23 temperature switches that require no external components and the design is facilitated with factory- programmed temperature thresholds.

A choice of factory-trimmed temperature trip points are available.

Pin selectable hysteresis of +2°C or +10°C allows flexibility to the design.

These parts typically consume only 17 µA of current and operate over the entire -55°C to +125°C t
