MAX8212CSA [Maxim]

The MAX8211 and MAX8212 are CMOS micro-power voltage detectors that provide power-fail warnings to microprocessors. They feature a comparator, a 1.15V bandgap reference, and an open-drain n-channel output driver. External resistors set the trip voltage, and a hysteresis output allows noise-free switching. The MAX8211 offers a current-limited output sink of 7mA, while the MAX8212 provides high output current capability. They are plug-in replacements for bipolar ICL8211/ICL8212 with advantages such as low quiescent current (5μA), improved threshold accuracy (±40mV), and a wide supply-voltage range (2.0V to 16.5V).
