Texas Instruments TLV9022QPWRQ1

Overview

TLV9022QPWRQ1 from Texas Instruments is an AEC-Q100 Grade 1 dual-channel automotive comparator with open-drain outputs, 300 µV input offset voltage, 100 ns propagation delay, and 16 µA per channel quiescent current across 1.65 V to 5.5 V supply. It operates from –40°C to +125°C ambient and features fault-tolerant inputs (–0.3 V to 6 V) and Power-On Reset for reliable startup in HEV/EV powertrain monitoring.

For engineers reviewing the TLV9022QPWRQ1 datasheet, TLV9022QPWRQ1 pinout, TLV9022QPWRQ1 application, or TLV9022QPWRQ1 equivalent, this page delivers verified technical context, package-specific pin functions, automotive-grade reliability data, and precise alternative selection guidance - all grounded in TI's official SNOSDA9E revision May 2024 documentation.

Technical Context

The TLV9022QPWRQ1 implements a rail-to-rail input architecture with internal ESD clamps enabling ±6 V fault tolerance beyond supply rails, and includes a dedicated Power-On Reset circuit that holds outputs in a known state until V_S ≥ 1.65 V. Its open-drain output stage supports level translation via external pull-up to voltages below or above V+, making it suitable for interfacing between mixed-voltage domains.

Each comparator channel delivers 50–200 V/mV open-loop gain, 60–70 dB CMRR at 5 V supply, and maintains ≤2 mV max input offset drift over temperature. The device uses a low-power bias network achieving 16 µA typical I_Q per channel while sustaining 100 ns propagation delay under 15 pF load - a validated speed-to-power balance for battery-sensitive automotive subsystems.

FAQ

What is the maximum input voltage the TLV9022QPWRQ1 can tolerate without damage?

The TLV9022QPWRQ1 supports input voltages from −0.3 V to +6 V relative to V− on both IN+ and IN− pins, independent of supply voltage. This fault-tolerant range allows direct connection to 12 V battery rails or sensor outputs exceeding V+, eliminating external clamping diodes in most automotive applications. Operation remains functional within this range without phase inversion or latch-up.

Does the TLV9022QPWRQ1 have built-in Power-On Reset (POR), and how does it behave?

Yes, TLV9022QPWRQ1 integrates a dedicated Power-On Reset circuit. During power-up, outputs remain in a known high-impedance (open-drain) state until the supply reaches ≥1.65 V, then settle to valid logic levels. This prevents false triggering in microcontroller interfaces or downstream logic during brown-out conditions - a critical feature confirmed in TI's SNOSDA9E datasheet Section 6.3.

Can the TLV9022QPWRQ1 operate from a 1.8 V supply, and what performance is guaranteed?

Yes, TLV9022QPWRQ1 is fully specified down to 1.8 V supply. At 1.8 V, it guarantees ≤2 mV input offset voltage, 100 ns propagation delay (high-to-low), 16 µA per channel quiescent current, and rail-to-rail input operation from (V−) − 0.2 V to (V+) + 0.2 V - all validated across −40°C to +125°C per Section 5.9 and 5.10 of the datasheet.

Is the TLV9022QPWRQ1 pin-compatible with other devices in the TLV902x-Q1 family?

TLV9022QPWRQ1 shares the same 8-pin TSSOP (PW) pinout with TLV9022QDRQ1 (SOIC), TLV9022QDGKRQ1 (VSSOP), and TLV9022QDSGRQ1 (WSON), as confirmed in Table 4-2 and Figure 4-3 of SNOSDA9E. All TLV9022-x-Q1 dual variants maintain identical pin functions - enabling footprint reuse across package options without layout changes.

What is the purpose of the exposed thermal pad on the TLV9022QPWRQ1 TSSOP package?

The exposed thermal pad on TLV9022QPWRQ1 must be soldered directly to the V− net on the PCB per TI's layout guidelines (Section 8.1). This connection provides a low-thermal-resistance path (R_θJB = 152.5°C/W) to the board, improving power dissipation and junction temperature stability - especially critical in sustained operation at +125°C ambient in automotive under-hood applications.
