Low quiescent current comparators

19 June 2002 Power Electronics / Power Management

Microchip's new low-power comparators operate down to 1,6 V with a low quiescent current of 600 nA and only 8 ms propagation delay. The MCP6531/42/43/44 and MCP646/47/48/49 devices are push-pull and open-drain respectively. With an operating voltage range of 5,5 V to 1,6 V, the MCP6546/47/48/49 have 10 V capability at the output, allowing limited control at voltages higher than the supply voltage. The 10 V capability feature eliminates the need for additional components to achieve signal transition from lower voltage to higher voltage stages. They offer rail-to-rail operation at both input and output. Typical power usage is 960 nW, and they are available in 8-pin PDIP, SOIC and MSOP and 14-pin PDIP, SOIC and TSSOP options.
