Texas Instruments TLV3704IPW

Overview

TLV3704IPW from Texas Instruments is a quad nanopower comparator with push-pull CMOS output, designed for ultra-low-quiescent-current sensing in battery-powered systems. It operates from 2.5V to 16V supply, draws only 560 nA per channel, supports input common-mode range from –0.1 V to V_CC + 5 V, and is rated for –40°C to +125°C industrial temperature operation. It enables precise voltage threshold detection in portable medical devices and security sensors.

For engineers reviewing the TLV3704IPW datasheet, TLV3704IPW pinout, TLV3704IPW application, or TLV3704IPW equivalent, key selection criteria include its 560 nA/channel supply current, rail-overlapping input range, push-pull output eliminating external pull-ups, 45 µs max high-to-low propagation delay at 10 mV overdrive, and TSSOP-14 packaging suitable for space-constrained PCB layouts.

Technical Context

The TLV3704IPW integrates four independent comparators sharing a single V_CC and GND, each featuring fail-safe inputs tolerant up to 20 V regardless of supply state and reverse-battery protection. Its internal power-on-reset (POR) holds outputs low for ≤3 ms during V_CC ramp-up, ensuring deterministic startup behavior in energy-harvesting and intermittent-power systems.

Input stage architecture supports both within-rail (–0.1 V to V_CC) and over-rail (up to V_CC + 5 V) operation with <1 pA bias current in low-common-mode region and ≤55 nA when inputs exceed V_CC. The push-pull output delivers rail-to-rail sourcing/sinking capability without external components, simplifying interface to microcontrollers and logic gates.

FAQ

What is the maximum input voltage allowed on TLV3704IPW pins when V_CC is unpowered?

The TLV3704IPW inputs are fail-safe up to 20 V regardless of V_CC state. When V_CC is 0 V, inputs may be held at any voltage from –0.1 V to 20 V without damage or excessive leakage-enabling hot-plug or pre-power signal conditioning. This specification is confirmed in Section 6.1 Absolute Maximum Ratings and Section 7.4.1.2 of the TLV3704IPW datasheet.

Does TLV3704IPW require external pull-up resistors on its outputs?

No, TLV3704IPW does not require external pull-up resistors because it features a push-pull CMOS output stage capable of actively driving both high and low states. Each output can source ≥2 µA at V_CC – 80 mV and sink ≥50 µA at 80 mV above GND-verified in Section 6.7 Electrical Characteristics. This eliminates BOM cost and standby current from pull-up networks.

What is the propagation delay variation of TLV3704IPW across temperature and supply voltage?

TLV3704IPW propagation delay varies from 16 µs (min, 50 mV overdrive) to 45 µs (max, 10 mV overdrive) at 12 V supply and 25°C. Over –40°C to +125°C, delay increases ≤15% at low overdrive; supply voltage change from 2.5 V to 16 V causes <10% variation-data confirmed in Figures 6-12 and 6-13 and Table 6-2 Switching Characteristics.

Can TLV3704IPW operate from a dual ±2.5 V supply?

Yes, TLV3704IPW supports dual-supply operation from ±1.25 V to ±8 V, as specified in Section 6.3 Recommended Operating Conditions. With ±2.5 V supplies, V_CC connects to +2.5 V and GND to –2.5 V, enabling true bipolar input sensing from –2.6 V to +7.5 V (–0.1 V to V_CC + 5 V). Input offset and propagation delay remain within datasheet limits.

How does the internal power-on-reset (POR) affect TLV3704IPW output behavior during startup?

During V_CC ramp-up, TLV3704IPW's internal POR holds all four outputs low for ≤3 ms after V_CC crosses 1.5 V-ensuring deterministic initial state before valid comparison begins. This behavior is documented in Section 7.3.1.1 and Figure 7-1, and applies identically across all channels in the TLV3704IPW device.
