+ + MCP6546/6R/6U/7/8/9 Open-Drain Output Sub-Microamp Comparators Features Description Low Quiescent Current: 600 nA/Comparator (typical) The Microchip Technology Inc. MCP6546/6R/6U/7/8/9 family of comparators, is offered in single (MCP6546, Rail-to-Rail Input: V - 0.3V to V + 0.3V SS DD MCP6546R, MCP6546U), single with chip select (CS) Open-Drain Output: V 10V OUT (MCP6548), dual (MCP6547) and quad (MCP6549) Propagation Delay: 4 s (typical, 100 mV Overdrive) configurations. The outputs are open-drain and are Wide Supply Voltage Range: 1.6V to 5.5V capable of driving heavy DC or capacitive loads. Single Available in SOT-23-5, SC-70-5* Packages These comparators are optimized for low power, Available in Single, Dual and Quad single-supply application with greater than rail-to-rail Chip Select (CS) with MCP6548 input operation. The output limits supply current surges Low Switching Current and dynamic power consumption while switching. The open-drain output of the MCP6546/6R/6U/7/8/9 family Internal Hysteresis: 3.3 mV (typical) can be used as a level-shifter for up to 10V using a pull- Temperature Range: up resistor. It can also be used as a wired-OR logic. - Industrial: -40C to +85C The internal Input hysteresis eliminates output switch- - Extended: -40C to +125C ing due to internal noise voltage, reducing current draw. These comparators operate with a single-supply Typical Applications voltage as low as 1.6V and draw a quiescent current of less than 1 A/comparator. Laptop Computers The related MCP6541/2/3/4 family of comparators from Mobile Phones Microchip has a push-pull output that supports rail-to- Metering Systems rail output swing and interfaces with CMOS/TTL logic.
