TLV9032QDGKRQ1

Comparators Overview

The TLV9032QDGKRQ1 is a dual-channel precision automotive comparator from Texas Instruments, designed for harsh environments. It operates on a supply voltage range of 1.65V to 5.5V and features a push-pull output stage capable of sourcing and sinking current. The device includes Power-On Reset (POR) functionality to ensure known start-up states. It offers low input offset voltage of 300μV typical, 100ns typical propagation delay, and low quiescent current of 16μA per channel. Inputs are fault-tolerant up to 6V without damage.

Comparators Feature Summary

• Push-pull output stage provides robust drive capability for capacitive loads like MOSFET gates or LEDs.
• Power-On Reset (POR) feature ensures outputs remain in a known state during system power-up and power-down sequences.
• Fault-tolerant inputs allow signals up to 6V without causing damage or output phase inversion.

Comparators Applications

• HEV/EV and power train systems
• Infotainment and cluster applications
• Body control module circuits

Comparators Procurement Notes

Verify the specific package suffix 'DGK' corresponds to the VSSOP-8 form factor required for your PCB layout. Confirm that the Q1 designation meets your specific AEC-Q100 qualification requirements for temperature grade and reliability standards before finalizing procurement.

Comparators Selection Notes

Select this component when a push-pull output is necessary to drive loads directly without external pull-up resistors. It is suitable for designs requiring rail-to-rail input voltage ranges that exceed the supply rails. Consider the 100ns propagation delay and 16μA quiescent current balance for speed-sensitive automotive applications.

Comparators Part Context

This part belongs to the TLV902x-Q1 and TLV903x-Q1 family of precision automotive comparators. While the TLV902x series utilizes open-drain outputs, the TLV903x series specifically employs push-pull outputs. The family shares common electrical characteristics such as low offset voltage and fault-tolerant inputs, differing primarily in output topology and pinout configurations.

Comparators FAQ

What is the difference between the TLV9032-Q1 and TLV9022-Q1?

The primary difference is the output stage. The TLV9032-Q1 features a push-pull output capable of sourcing and sinking current, whereas the TLV9022-Q1 has an open-drain output that requires an external pull-up resistor.

How does the Power-On Reset (POR) feature function?

The POR feature holds the output in a known state until the supply voltage reaches a minimum threshold, preventing output transients during system power-up and power-down cycles.
