TLV3603QDCKRQ1

Comparators Overview

The TLV3603QDCKRQ1 is a single-channel, high-speed analog comparator qualified for automotive applications under AEC-Q100 standards. It operates within a supply voltage range of 2.4 V to 5.5 V and supports an ambient temperature range from -40°C to +125°C. The device features a typical propagation delay of 2.5 ns, a maximum input offset voltage of ±5 mV, and a quiescent current of 7.8 mA. It utilizes a push-pull output stage and is housed in a 6-pin SC-70 package.

Comparators Feature Summary

• Features an adjustable hysteresis control pin that allows external resistor configuration for noise suppression or enables a latch function to hold the output state.
• Provides rail-to-rail input capability with an input common-mode range extending 200 mV beyond both power supply rails.
• Includes a Power-on-Reset (POR) circuit that ensures a known low output startup condition during power ramp-up.

Comparators Applications

• DC/DC converter feedback loops
• Inverter and motor control systems
• Fuel Cell Control Unit (FCCU)
• Battery Management System (BMS)
• Mechanically scanning LIDAR

Comparators Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging format. Confirm the component meets AEC-Q100 Grade 1 reliability requirements for the target automotive environment. Ensure the design accounts for the specified thermal resistance values when operating at maximum ambient temperatures.

Comparators Selection Notes

Select this component over the TLV3601-Q1 when adjustable hysteresis or output latching functionality is required. The device offers identical speed and package dimensions to the five-pin variant while providing additional control pins. Verify that the 6-pin SC-70 footprint fits the available board space constraints.

Comparators Part Context

This part belongs to the TLV360x-Q1 family of 325 MHz high-speed comparators. It shares core electrical characteristics with the TLV3601-Q1 but adds specific control features via the LE/HYST pin. The family is designed for narrow pulse width detection and data recovery applications requiring fast response times.

Comparators Replacement Considerations

The TLV3601-QDCKRQ1 serves as a functional substitute if hysteresis adjustment and latching are not needed. Both devices share the same SC-70-6 footprint and electrical performance metrics.

Comparators FAQ

How does the LE/HYST pin function?

Connecting an external resistor to ground configures adjustable hysteresis for noise immunity. Pulling the pin low activates a latch mode that holds the output at its last active state.

What is the input common-mode voltage range?

The inputs can operate from 200 mV below the negative supply rail to 200 mV above the positive supply rail.
