ADCMP350YKS-REEL7

Overview

The ADCMP350YKSZ-REEL7 is a single-channel analog comparator with an integrated 0.6 V reference, housed in a 4-lead SC-70 (KS-4) package. It operates on a supply voltage range of 2.25 V to 5.5 V with a typical supply current of 10 µA. The device features an open-drain active-low output capable of tolerating up to 22 V on the input and output pins. Key electrical characteristics include a propagation delay of 5 µs, 15 mV internal hysteresis, and an operating temperature range from −40°C to +125°C.

Feature Summary

• Integrates a fixed 0.6 V reference for simplified voltage detection circuits
• Features high-voltage tolerant inputs and open-drain outputs supporting up to 22 V
• Provides low power consumption suitable for battery-operated portable equipment
• Includes internal hysteresis to prevent output oscillation during noisy transitions

Applications

• Voltage detectors
• Microprocessor systems
• Battery monitors
• Portable equipment

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm the KS-4 package marking code M55 matches physical inspection requirements. Ensure the open-drain active-low configuration aligns with system logic levels. Check RoHS compliance status as indicated by the Z suffix in the ordering guide.

Selection Notes

Select this component for applications requiring a fixed threshold without external reference resistors. The open-drain output requires an external pull-up resistor; ensure the pull-up voltage does not exceed the 22 V tolerance limit. Consider the 5 µs propagation delay when designing for fast signal transitions. Verify that the 0.6 V trip point meets the specific voltage monitoring requirements of the target circuit.

Part Context

This part belongs to the ADCMP35x family, which includes variants with different output polarities and configurations. While sharing the same core comparator architecture and low-power specifications, the ADCMP350 differs from the ADCMP354 and ADCMP356 primarily through its active-low open-drain output stage. All members utilize the compact SC-70 footprint.

Replacement Considerations

Direct functional substitutes within the same datasheet include ADCMP354YKSZ-REEL7 and ADCMP356YKSZ-REEL7. Note that these alternatives feature non-inverting inputs and different output stages (open-drain active-high or push-pull). Cross-compatibility requires verifying output polarity and input connection requirements.
