TPA2031Q-S5TR-S

Comparators Overview

The TPA2031Q-S5TR-S is a micro-power comparator featuring push-pull outputs and low input offset voltage. It operates on a supply voltage range of 1.8 V to 5.5 V with a quiescent current of 350 μA per channel. The device includes an internal charge pump that powers the input stage above the external supply, enabling linear operation over a wide common-mode input range extending 100 mV beyond the rails. It offers a propagation delay of 55 ns and an input offset voltage of ±6 mV. Qualified for automotive applications under AEC-Q100 Grade 1 standards, it functions reliably within a temperature range of −40°C to +125°C.

Comparators Procurement Notes

Verify the specific ordering suffix S5TR-S against the manufacturer's official documentation to confirm package type, reel quantity, and environmental compliance status. Ensure the component meets the required AEC-Q100 Grade 1 qualification for the intended automotive operating temperature range. Cross-reference the pin configuration and electrical specifications with the latest datasheet revision to guarantee compatibility with the target system design.

Comparators Selection Notes

Select this component when a low-power, high-speed comparator with rail-to-rail input capabilities is required. The internal charge pump architecture makes it suitable for applications where the input signal may exceed the positive supply rail. Consider its automotive qualification and wide operating temperature range for robust deployment in vehicle electronics. Evaluate the push-pull output drive strength against load requirements to ensure proper signal integrity.

Comparators FAQ

How does the internal charge pump affect the input common-mode range?

The internal charge pump powers the input stage with a supply rail higher than the external supply (+VS). This allows the differential input pair to operate linearly even when the input voltage extends up to 100 mV beyond the positive supply rail.

What is the maximum short-circuit current capability of the output?

The short-circuit current varies with supply voltage. At 5 V, it is typically 40 mA; at 3.3 V, it is 25 mA; and at 1.8 V, it is 5 mA.
