Texas Instruments TLV9032DSGR

Overview

TLV9032DSGR from Texas Instruments is a dual-channel, precision rail-to-rail input comparator with push-pull output, 300μV max input offset voltage, 100ns typical propagation delay, and 16μA per-channel quiescent current at 1.65V–5.5V supply. It operates across –40°C to +125°C and features fault-tolerant inputs (withstand up to 6V), enabling robust voltage monitoring in motor drive feedback loops.

For engineers reviewing the TLV9032DSGR datasheet, TLV9032DSGR pinout, TLV9032DSGR application, or TLV9032DSGR equivalent, key selection criteria include its push-pull output drive capability (±4mA), low-input-bias-current (5pA) for high-impedance sensing, and industrial temperature-grade performance in compact WSON-8 packaging.

Technical Context

The TLV9032DSGR implements a precision comparator core with rail-to-rail input stage tolerant to overvoltage up to 6V beyond V–, eliminating external clamping in noisy industrial environments. Its push-pull output delivers symmetrical sourcing/sinking (≥4mA) without external pull-up, supporting direct LED driving or MOSFET gate control.

It achieves 100ns propagation delay at 5V supply with only 16μA per channel quiescent current, delivering an optimized speed-power trade-off for battery-sensitive and thermally constrained applications. Input offset drift is ±0.5μV/°C over full temperature range.

FAQ

What is the maximum input voltage the TLV9032DSGR can tolerate without damage?

The TLV9032DSGR features fault-tolerant inputs rated for up to 6V relative to V–, regardless of the V+ supply voltage. This allows direct connection to signals exceeding the supply rails-such as battery terminals or unregulated sensor outputs-without external clamping diodes or series resistors. Operation remains functional and non-inverting within this range, as confirmed in the Absolute Maximum Ratings and Functional Description sections of the official datasheet.

Does the TLV9032DSGR support rail-to-rail input common-mode voltage?

Yes, the TLV9032DSGR supports a rail-to-rail input common-mode range from (V– –0.2V) to (V+ +0.2V) across the full –40°C to +125°C temperature range. This enables accurate comparison of signals near or slightly beyond the supply rails-critical for battery voltage monitoring, supply sequencing, and sensor interface applications where signal headroom is limited.

Can the TLV9032DSGR drive a MOSFET gate directly?

Yes, the TLV9032DSGR's push-pull output can source and sink ≥4mA at 5V supply, making it capable of directly driving the gate capacitance of small-signal MOSFETs (e.g., Si2302, DMN2004K) without external buffers. Rise/fall times are ≤3ns into 15pF, supporting switching speeds appropriate for enable/disable control in power management circuits.

What is the thermal pad connection requirement for TLV9032DSGR?

The exposed thermal pad on the TLV9032DSGR (WSON-8 package) must be soldered directly to the V– (ground) net on the PCB. This connection serves both thermal dissipation and electrical reference functions. TI's datasheet explicitly states "Connect exposed thermal pad directly to V– pin" to ensure proper junction temperature control and stable operation under continuous load conditions.

How does the TLV9032DSGR differ from the TLV9022DSGR?

The TLV9032DSGR and TLV9022DSGR share identical package, pinout, offset voltage, propagation delay, and quiescent current-but differ exclusively in output architecture: TLV9032DSGR uses push-pull outputs, while TLV9022DSGR uses open-drain outputs. This makes TLV9032DSGR suitable for applications requiring active-high signaling or bidirectional drive, whereas TLV9022DSGR requires external pull-up resistors and supports wired-OR configurations.
