NCS2202SN2T1G

Comparators Overview

The NCS2202SN2T1G is a single-channel analog comparator from the NCS2200 series, manufactured by onsemi. It operates within a supply voltage range of 0.85 V to 6.0 V and consumes a typical supply current of 10 µA. The device features an open-drain output configuration with rail-to-rail input performance. Key electrical characteristics include a typical propagation delay of 1000 ns at 20 mV overdrive, an input offset voltage of ±10 mV, and an input bias current of 1 pA. It supports a common-mode rejection ratio (CMRR) of 65 dB and a power supply rejection ratio (PSRR) of 55 dB. The component is housed in a SOT-23-5 package.

Comparators Feature Summary

• Rail-to-rail input capability extending beyond supply rails without phase inversion
• Ultra-low power consumption suitable for battery-operated systems
• Internal hysteresis for clean output switching
• Open-drain output facilitates mixed-voltage logic interfacing

Comparators Applications

• Single cell NiCd/NiMH battery powered applications
• Automotive systems requiring AEC-Q100 qualified components
• Alarm and security systems
• Logic level translation between different voltage domains

Comparators Procurement Notes

Verify the specific pinout style required for your design, as the SN2T1 suffix corresponds to Style 2 pinout configuration in the SOT-23-5 package. Confirm that the open-drain output architecture aligns with your pull-up resistor requirements and system voltage levels. Ensure the operating temperature range meets your environmental specifications, as the standard NCS prefix covers -40°C to +105°C. Check for automotive qualification needs; if AEC-Q100 compliance is mandatory, select the NCV prefix variant instead.

Comparators Selection Notes

Select this component when sub-one volt operation and minimal quiescent current are critical constraints. The open-drain output is ideal for interfacing with higher voltage logic levels than the supply voltage, provided an external pull-up is used. Consider the NCS2200 variant if a push-pull output is preferred for direct driving capabilities without external resistors. Evaluate the propagation delay against your signal speed requirements, as this device is optimized for low power rather than high-speed response.

Comparators Part Context

The NCS2202SN2T1G belongs to the NCS2200 series, recognized as an industry-first sub-one volt low-power comparator family. This series utilizes a modified analog CMOS process with depletion MOSFET devices to achieve operation down to 0.85 V. The NCS2202 specifically offers an open-drain output, distinguishing it from the push-pull NCS2200, making it suitable for mixed-voltage applications where the output can be pulled up to 6.0 V.
