MAX9644/MAX9645/ nanoPower Comparators with MAX9646 Precision Reference in 4-Bump UCSP General Description Benefits and Features The MAX9644/MAX9645/MAX9646 are small, single Tiny, 1mm x 1mm x 0.6mm 4-Bump UCSP comparators, 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 -0.3V to +5.5V Input Voltage Range both a miniature 4-bump UCSP package with a 1mm x 1mm footprint (as small as two 0402 resistors) and a Internal 0.2V Reference Trimmed to 1% Accuracy 5-pin SOT23 package. 15s Propagation Delay The ICs feature an input voltage range of -0.3V to +5.5V, -40C to +85C Extended Temperature Range independent of supply voltage. These devices maintain high impedance at the inputs even when powered down (V or V = 0V). They also feature internal filtering to CC REF Ordering Information provide high RF immunity. PART PIN-PACKAGE TOP MARK The ICs have an internal 0.2V reference. These devices MAX9644EBS+G45 4 UCSP +AGL feature either a push-pull or an open-drain output. They consume only 700nA (max) supply current and operate MAX9644EUK+ 5 SOT23 +AFJN down to V = 1V over the extended -40C to +85C CC MAX9645EBS+G45 4 UCSP +AGM temperature range. MAX9645EUK+ 5 SOT23 +AFJO Applications MAX9646EBS+G45 4 UCSP +AGN Cell Phones MAX9646EUK+ 5 SOT23 +AFJP Portable Media Players Note: All devices are specified over the extended -40C to Electronic Toys +85C operating temperature range. Notebook Computers +Denotes a lead(Pb)-free/RoHS-compliant package. Portable Medical Devices G45 = Protective die coating.
