Key Features
- Push-pull output eliminates the need for an external pull-up resistor, reducing component count and simplifying PCB design versus open-drain comparators
- 5 µA maximum input bias current and 5 mV maximum offset voltage enable accurate threshold comparison without significant load on high-impedance signal sources
- Ultra-compact SOT-23 5-pin package occupies minimal board space, ideal for space-constrained portable and wearable device designs
Applications
The TLV3601DCKR is used in battery management systems and overcurrent protection circuits where a fast analog comparator must trigger a digital response when a sensed voltage crosses a threshold. Its push-pull output interfaces directly to logic gates, microcontroller interrupt pins, and gate driver inputs without additional components, making it efficient for level-detection in switching power supplies and motor drives. The device also finds use in clock recovery, zero-crossing detection for AC waveforms, and precision window comparator circuits in test-and-measurement instrumentation.

Frequently Asked Questions
What input bias current and offset voltage does the TLV3601DCKR specify for threshold accuracy?
The TLV3601DCKR specifies a maximum input bias current of 5 µA and a maximum input offset voltage of 5000 µV (5 mV) at 25 °C. For high-impedance source applications, the 5 µA bias current flowing through a 10 kohm source resistance introduces only 50 mV of additional error, so source impedances below 1 kohm keep offset-induced error under 5 mV in most threshold-detection circuits.
How does the push-pull output of the TLV3601DCKR differ from an open-drain comparator output?
Unlike open-drain comparators that require an external pull-up resistor to set the logic high level, the TLV3601DCKR push-pull output actively drives both logic high and logic low, sourcing and sinking current without any passive components. This reduces parts count, speeds up rising-edge transitions, and allows direct connection to CMOS logic inputs and microcontroller interrupt pins in 3.3 V or 5 V systems.
Which supply voltage range does the TLV3601DCKR support, and can it operate on a single 3.3 V rail?
The TLV3601DCKR operates from a single supply in the range of approximately 2.7 V to 5.5 V, making it fully compatible with 3.3 V and 5 V logic systems without a dual-supply bias network. On a 3.3 V rail, the push-pull output swings to within a few hundred millivolts of supply and ground, providing clean digital transitions for downstream CMOS gates or microcontroller digital inputs.
For a motor overcurrent protection circuit, how quickly does the TLV3601DCKR respond to an input crossing?
The TLV3601DCKR is designed as a high-speed comparator with propagation delay in the range of a few nanoseconds to tens of nanoseconds depending on overdrive voltage, making it capable of detecting current spikes with rise times under 100 ns. This fast response time is critical in motor control and power supply protection applications where a 100 ns to 500 ns reaction window prevents MOSFET or IGBT damage from overcurrent conditions exceeding 10 A to 100 A.
What is the board footprint of the TLV3601DCKR SOT-23 package, and how does it compare to an SO-8 comparator?
The TLV3601DCKR uses a 5-pin SOT-23 package measuring approximately 2.9 mm x 1.6 mm with 0.95 mm pin pitch, which is roughly 4x to 6x smaller in area than a standard SO-8 package at 4.9 mm x 3.9 mm. This compact footprint is advantageous in portable medical devices, wearable sensors, and IoT modules where PCB area is limited to a few square centimeters per function.
