| TS7221 Single BiCMOS rail-to-rail micropower comparator Features Rail-to-rail inputs Open drain output Supply operation from 2.7V to 10V Typical supply current: 6A @ 5V Response time of 0.5s at 5V Low input current ESD protection: 2kV (HBM), 200V (MM) Available in tiny SOT23-5 package TS7221 Open drain output 1 2 + IN+ 3 4 IN- L SOT23-5L Applications Battery-powered systems Notebooks and PDAs PCMCIA cards Cellulars and mobile communication Alarm and security systems Replacement of amplifiers used in comparator configuration for better performance OUT Vcc+ 5 Vcc- Description The TS7221 is a micropower comparator featuring rail-to-rail input performance in a tiny SOT23-5 package. This comparator is ideally suited to space and weight-critical applications. It is fully specified at 2.7V, 5V and 10V operation over the industrial temperature range (-40C to +85C). The TS7221 features an open drain output stage. The speed-to-power ratio makes this device ultraversatile for a wide range of applications.
