Texas Instruments TLV1704AQPWRQ1

Overview

TLV1704AQPWRQ1 from Texas Instruments is a quad-channel automotive-grade microPower comparator with rail-to-rail inputs, 55 µA per channel quiescent current, 560 ns low propagation delay (low-to-high), and open-collector outputs capable of sinking up to 20 mA while operating from 2.2 V to 36 V. It is used in overvoltage/undervoltage detection circuits within automotive body control modules requiring AEC-Q100 Grade 1 qualification.

For engineers reviewing the TLV1704AQPWRQ1 datasheet, TLV1704AQPWRQ1 pinout, TLV1704AQPWRQ1 application, or TLV1704AQPWRQ1 equivalent, key selection criteria include input offset voltage (±3.5 mV typ), temperature range (–40°C to +125°C), ESD robustness (HBM ±1000 V), TSSOP-14 package compatibility, and open-collector output flexibility for wired-OR configurations.

Technical Context

The TLV1704AQPWRQ1 implements a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails, enabling reliable operation in high-side sensing and wide common-mode applications. Its open-collector output supports pull-up to any voltage up to 36 V above the negative supply-decoupled from the device's own supply voltage.

Each of the four comparators operates independently with matched switching characteristics: typical propagation delay is 560 ns (low-to-high) and 460 ns (high-to-low) at 100 mV input overdrive, with stable performance across –40°C to +125°C and supply voltages from 2.2 V to 36 V.

FAQ

What is the maximum allowable supply voltage for TLV1704AQPWRQ1?

The absolute maximum supply voltage for TLV1704AQPWRQ1 is 40 V (or ±20 V), but the recommended operating range is 2.2 V to 36 V. Exceeding 40 V risks permanent damage per Absolute Maximum Ratings. Operation at 36 V is fully specified across –40°C to +125°C, with validated performance in propagation delay, offset voltage, and output sink capability. Always use a 0.1-µF ceramic bypass capacitor at the V+ pin when operating near maximum voltage.

Does TLV1704AQPWRQ1 support dual-supply operation?

Yes, TLV1704AQPWRQ1 supports dual-supply operation from ±1.1 V to ±18 V, as explicitly stated in the Recommended Operating Conditions. In dual-supply mode, V+ connects to the positive rail and V− to the negative rail; inputs and outputs remain referenced to the local V−. The rail-to-rail input stage functions correctly across both rails, and the open-collector outputs can be pulled up to any voltage ≤36 V above V−-enabling asymmetric configurations like +5 V / –12 V supplies.

What is the guaranteed input offset voltage specification for TLV1704AQPWRQ1?

The TLV1704AQPWRQ1 is the "A" grade variant, guaranteeing input offset voltage of ±3.5 mV maximum at TA = 25°C and VS = 2.2 V to 36 V. Over the full temperature range (–40°C to +125°C), the maximum offset is ±5.5 mV. This is tighter than the standard TLV1704QPWRQ1 (no "A"), which has no guaranteed offset spec. The "A" grade is binned and tested to ensure compliance, making it suitable for precision threshold applications like battery cell voltage monitoring.

Can TLV1704AQPWRQ1 outputs drive an LED directly?

Yes, TLV1704AQPWRQ1 outputs can drive an LED directly when configured as open-collector sinks. With a 5 V pull-up and 2 mA LED current, the output voltage drop is ≤600 mV (at IO = 0 mA) and ≤900 mV (at IO = 4 mA), ensuring sufficient forward voltage margin. The device supports up to 20 mA sink current per output, well above typical LED requirements. Ensure the series resistor limits current to avoid exceeding the 20 mA absolute maximum, and verify thermal dissipation in continuous-drive scenarios.

Is TLV1704AQPWRQ1 pin-compatible with other TLV170x-Q1 variants?

No-TLV1704AQPWRQ1 (TSSOP-14) is not pin-compatible with TLV1701-Q1 (SOT-23-5/SC-70-5) or TLV1702-Q1 (VSSOP-8). However, all TLV170x-Q1 devices share identical electrical behavior, pin functions per channel, and functional block architecture. Pin mapping within the TSSOP-14 package is consistent across all TLV1704-Q1 variants (e.g., TLV1704QPWRQ1 and TLV1704AQPWRQ1), enabling direct substitution without layout changes when upgrading to the "A" grade.
