MAX973
Description
The MAX971- MAX974 and MAX981- MAX984 single/ dual/quad low-voltage parators feature the lowest power consumption available. These micropower devices draw less than 4µA supply current over temperature (MAX971/MAX972/MAX981/MAX982), and include an internal 1.182V ±1% (MAX971/MAX973/ MAX974) or ±2% (MAX981- MAX984) voltage reference and programmable hysteresis. Ideal for 3V or 5V single-supply applications, these devices operate from a single 2.5V to 11V supply (or ±1.25V to ±5.5V dual supplies), and each parator’s input voltage ranges from the negative supply rail to within 1.3V of the positive supply. The single MAX971/MAX981 and the dual MAX973/ MAX982/MAX983 provide a unique, simple method for adding hysteresis without feedback or plicated equations, simply by using the HYST pin plus two resistors. The MAX971- MAX974 and MAX981- MAX984’s opendrain outputs permit wire-ORed configurations. Thanks to an 11V output range and separate GND pin for the output transistor...
