MAX9644/MAX9645/MAX9646 19-5803 Rev 1 10/11 Low-Power Comparators with Precision Reference in 4-Bump UCSP General Description Features The MAX9644/MAX9645/MAX9646 are small, single com- Tiny, 1mm x 1mm x 0.6mm 4-Bump UCSP parators, ideal for a wide variety of portable electronics Footprint = Two 0402 Resistors applications such as cell phones, media players, and Also Available in a 5-Pin SOT23 Package notebooks that have extremely tight board space and Ultra-Low Operating Current (700nA max) power constraints. These comparators are offered in both a miniature 4-bump UCSP package with a 1mm x 1mm -0.3V to +5.5V Input Voltage Range footprint (as small as two 0402 resistors) and a Internal 0.2V Reference Trimmed to 1% Accuracy 5-pin SOT23 package. The ICs feature an input voltage range of -0.3V to 15s Propagation Delay +5.5V, independent of supply voltage. These devices -40C to +85C Extended Temperature Range maintain high impedance at the inputs even when pow- ered down (V or V = 0V). They also feature inter- CC REF nal filtering to provide high RF immunity. The ICs have an internal 0.2V reference. These devices Ordering Information feature either a push-pull or an open-drain output. They consume only 700nA (max) supply current and operate PART PIN-PACKAGE TOP MARK down to V = 1V over the extended -40C to +85C tem- CC perature range.
