TLV4021S5MYKAR

Comparators Overview

The TLV4021S5MYKAR is a low-power, high-accuracy comparator from the Texas Instruments TLV40x1 family. It features a non-inverting input configuration with an open-drain output stage and a fixed internal threshold of 3.2 V. The device operates within a supply voltage range of 1.6 V to 5.5 V and consumes a quiescent current of 2 µA. It provides precision hysteresis of 54 mV and supports an operating temperature range from –40°C to +125°C. The component is housed in a compact 0.73 mm × 0.73 mm DSBGA package.

Comparators Feature Summary

• Integrates a fixed 3.2 V switching threshold without requiring external resistor dividers
• Provides known startup conditions via a Power-on-Reset circuit that forces the output to a defined state during power transitions
• Includes factory-trimmed precision hysteresis to reject input glitches and ensure stable digital outputs in noisy environments

Comparators Applications

• Lithium ion battery monitoring
• Battery management and protection systems
• Current and voltage sensing circuits
• Analog front end signal conditioning
• Point of load regulators

Comparators Procurement Notes

Verify the specific suffix MYKAR against the manufacturer's orderable addendum to confirm the exact package type and tape-and-reel specifications. Ensure the selected variant matches the required non-inverting input and open-drain output topology for the design. Cross-reference the datasheet revision history to confirm the documentation covers the S5x fixed threshold configuration.

Comparators Selection Notes

Select this component when space constraints require a sub-millimeter footprint combined with low standby current consumption. The fixed 3.2 V threshold eliminates the need for external resistors, simplifying the bill of materials. Choose this part over other TLV40x1 variants if the application specifically requires a non-inverting logic response and an open-drain interface for level shifting or wired-OR configurations.

Comparators Part Context

This device belongs to the TLV40x1 family of small-size, low-power comparators designed for portable and battery-powered electronics. The family includes variants with different input polarities (inverting/non-inverting), output stages (push-pull/open-drain), and reference thresholds (0.2 V, 0.5 V, 1.2 V, and fixed 3.2 V). The TLV4021S5x series specifically targets applications needing a higher fixed threshold than the standard reference options.

Comparators Replacement Considerations

Direct substitutes within the same family include TLV4031S5x (inverting input) and TLV4041S5x (push-pull output). Verify pin compatibility and electrical characteristics before substitution.
