+ + + MCP6566/6R/6U/7/9 1.8V Low-Power Open-Drain Output Comparator Features Description Propagation Delay at 1.8 V : The Microchip MCP6566/6R/6U/7/9 family of open- DD drain output comparators is offered in single, dual and - 56 ns (typical) high-to-low quad configurations. Low Quiescent Current: 100 A (typical) These comparators are optimized for low-power 1.8V, Input Offset Voltage: 3 mV (typical) single-supply applications with greater than rail-to-rail Rail-to-Rail Input: V 0.3V to V + 0.3V SS DD input operation. The internal input hysteresis eliminates Open-Drain Output output switching due to internal input noise voltage, Wide Supply Voltage Range: 1.8V to 5.5V reducing current draw. Available in Single, Dual and Quad The open-drain output of the MCP6566/6R/6U/7/9 Packages: SC70, SOT-23, SOIC, MSOP, TSSOP family requires a pull-up resistor. It supports pull-up voltages that are above and below V , which can be DD Typical Applications used to level shift. The output toggle frequency can reach a typical 4 MHz (typical) while limiting supply Laptop Computers current surges and dynamic power consumption during Mobile Phones switching. Handheld Electronics This family operates with a single-supply voltage of 1.8V RC Timers to 5.5V while drawing less than 100 A/comparator of Alarm and Monitoring Circuits quiescent current (typical).
