Texas Instruments TLV3704IPWRG4

Overview

TLV3704IPWRG4 from Texas Instruments is a quad nanopower comparator with push-pull CMOS output, designed for ultra-low-power sensing and threshold detection in battery-powered systems. It draws only 560 nA per channel, operates from 2.5 V to 16 V, 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.

For engineers reviewing the TLV3704IPWRG4 datasheet, TLV3704IPWRG4 pinout, TLV3704IPWRG4 application, or TLV3704IPWRG4 equivalent, key selection criteria include quiescent current budget, rail-overlapping input range, push-pull output drive capability without external pull-up, reverse-battery protection up to 20 V, and compatibility with 14-pin TSSOP layout constraints.

Technical Context

The TLV3704IPWRG4 implements a precision comparator core with fail-safe inputs capable of operating 5 V above V_CC without damage, enabling direct monitoring of higher-voltage rails (e.g., 12 V battery) while powered from a lower 3.3 V supply. Its internal power-on-reset circuit holds outputs low for ≤3 ms during V_CC ramp-up, ensuring deterministic startup behavior.

Each of its four independent channels features matched propagation delays (t_PLH/t_PHL ≤ 45 µs at 10 mV overdrive), 2.8 mV typical input hysteresis, and 76 dB minimum CMRR - all specified across the full –40°C to +125°C range and supported by reverse-battery protection up to 20 V.

FAQ

What is the maximum input voltage allowed on TLV3704IPWRG4 pins when V_CC = 3.3 V?

The TLV3704IPWRG4 supports an input common-mode range from –0.1 V to V_CC + 5 V. With V_CC = 3.3 V, inputs may safely reach up to 8.3 V. Additionally, the device's fail-safe inputs withstand up to 16 V regardless of V_CC state - meaning TLV3704IPWRG4 remains undamaged even if 12 V is applied while unpowered or at 0 V.

Does TLV3704IPWRG4 require external pull-up resistors on its outputs?

No. TLV3704IPWRG4 features a push-pull CMOS output stage that actively drives both high and low states. Unlike open-drain comparators, TLV3704IPWRG4 does not require external pull-up resistors - reducing component count, eliminating leakage paths, and improving rise/fall time consistency across temperature and supply voltage.

Can TLV3704IPWRG4 operate from a single 2.5 V supply across the full industrial temperature range?

Yes. TLV3704IPWRG4 is fully specified from 2.5 V to 16 V single supply across –40°C to +125°C. At 2.5 V, it maintains 560 nA typical supply current per channel, 2.8 mV typical hysteresis, and propagation delays ≤80 µs - enabling reliable operation in energy-harvesting and coin-cell-powered systems where minimum supply headroom is critical.

How does the power-on-reset (POR) function behave in TLV3704IPWRG4?

TLV3704IPWRG4 incorporates an internal POR circuit that activates when V_CC crosses 1.5 V during power-up or power-down. For up to 3 ms after crossing this threshold, all four outputs (1OUT–4OUT) are held low - guaranteeing a known, safe initial state. Once the POR timeout expires and V_CC exceeds the minimum operating voltage, outputs reflect real-time input comparisons.

Is TLV3704IPWRG4 pin-compatible with other TLV370x variants like TLV3704CDR or TLV3704IN?

Yes - all TLV3704 variants share identical pin configuration and electrical functionality across packages (TSSOP PW, SOIC D, PDIP N). TLV3704IPWRG4 uses the same 14-pin mapping defined in the datasheet for TLV3704, ensuring drop-in replacement between suffixes when thermal and mechanical constraints allow. Layout adaptation is required only for package-specific footprint differences.
