| Back NCS2300 Series Advance Information High Voltage Comparators The NCS2300 Series are ultra-low power comparators. These devices consume only 11 mA of supply current. They operate at a wide voltage range of 1.7 V to 12 V. Additional features include no output phase inversion when transitioning in/out of tri-state mode, internal hysteresis which allows for clean output switching, and rail-to-rail input performance. The NCS2300 Series are available in the tiny SOT23-5 or SOT23-6 package with two industry standard pinouts. The NCS2301/3 Series in the SOT23-6 package features an enable function which can be externally controlled. This lowers current consumption to 1.8 mA and allows for users to implement these devices in power sensitive applications such as portable electronics.

NCS2300 Series Input Common Mode Voltage vs. Supply Voltage Figure 14. NCS2300 Series Disabled Supply Current OPERATING DESCRIPTION The NCS2300 Series are ultra-low power comparators. These devices consume only 11 A of supply current while achieving a typical propagation delay of 1.1 s at 10 mV overdrive. They are guaranteed to operate at a low voltage of 1.7 V up to 12 V. This is accomplished by the use of a modified analog CMOS process which implements depletion MOSFET devices. The common-mode input voltage range extends 0.1 V above the upper and lower rail. They are available in SOT23-5 (compatible with the TSOP-5) and SOT23-6 packages. The SOT23-6 has the enable function which can be externally controlled. It allows for lower current consumption of 1.8 A. This makes the devices suitable for implementation in power sensitive applications such as portable electronics. When the enable pin is at a low level, the output will remain at a high or low level. The output will not respond to any changes at the input pins. VCC Conversely, when the enable pin is at a high level, the output will respond to change at the input pins. The enable pin should be connected to VCC when not in use. In addition, with the added feature of internal hysteresis, this allows for greater noise immunity and clean output switching. Output Stage The NCS2300/1 has a complementary output which drives rail-to-rail output swing. The NCS2302/3 has an open drain N-channel output that can be pulled up to 12 V (max) with an external pull- up resistor. This allows for mixed-voltage system applications These devices can operate up to an 8.0 mA load. The output stage is designed so that shoot through current is minimized while switching. This enhancement eliminates the need for bypass capacitors. There is no output phase reversal when switching in or out of tri-state mode.
