   Full Temperature Range

♦ No External Components Required

♦ Low Cost

♦ 30µA Supply Current

♦ Factory-Programmed Thresholds from

   -45°C to +115°C in 10°C Increments

♦ Open-Drain Output (MAX6501/MAX6503)

   Push-Pull Output (MAX6502/MAX6504)

♦ Pin-Selectable +2°C or +10°C Hysteresis

♦ SOT23-5 and TO220-7 Packages
