Texas Instruments TLV3702CDGKRG4

Overview

TLV3702CDGKRG4 from Texas Instruments is a dual 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, features –0.1V to VCC + 5V input common-mode range, 560 nA per channel supply current, and is rated for 0°C to 70°C commercial temperature range. It serves as a precision threshold detector in portable medical devices and security sensors.

For engineers reviewing the TLV3702CDGKRG4 datasheet, TLV3702CDGKRG4 pinout, TLV3702CDGKRG4 application, or TLV3702CDGKRG4 equivalent, key selection criteria include nanoscale supply current, rail-exceeding input range, push-pull output drive without external pull-up, reverse-battery protection up to 20V, and MSOP-8 packaging for space-constrained PCBs.

Technical Context

The TLV3702CDGKRG4 implements a proprietary input stage enabling over-the-rail operation (inputs up to VCC + 5V) while maintaining sub-1pA bias current in low-common-mode regions and ≤55nA when over-rail. Its internal Power-On Reset (POR) holds outputs low for ≤3ms during power ramp-up, ensuring deterministic startup behavior.

It uses a push-pull CMOS output stage delivering VOH ≥ VCC – 80 mV (at 2 µA) and VOL ≤ 8 mV (at 2 µA), eliminating need for external pull-up resistors. Propagation delay is 34 µs (low-to-high) and 45 µs (high-to-low) at 10 mV overdrive with 10 pF load, supporting reliable timing in slow-slew analog monitoring circuits.

FAQ

What is the maximum input voltage allowed on TLV3702CDGKRG4 pins?

The TLV3702CDGKRG4 supports an input common-mode voltage range from –0.1 V to VCC + 5 V, with absolute maximum input voltage limited to 20 V (per Absolute Maximum Ratings). This means inputs may safely exceed the positive supply rail by up to 5 V, provided total voltage does not surpass 20 V - enabling direct battery voltage monitoring without level-shifting circuitry in the TLV3702CDGKRG4 design.

Does TLV3702CDGKRG4 require external pull-up resistors on its outputs?

No, TLV3702CDGKRG4 does not require external pull-up resistors because it features a push-pull CMOS output stage. Each output (1OUT and 2OUT) actively drives high or low depending on the input differential, delivering VOH ≥ VCC – 80 mV and VOL ≤ 8 mV under specified loads. This eliminates pull-up components, reduces standby current, and improves signal integrity in the TLV3702CDGKRG4 implementation.

What is the operating temperature range for TLV3702CDGKRG4?

The TLV3702CDGKRG4 is a commercial-grade device rated for operation from 0°C to 70°C ambient temperature. This is confirmed by its "C" suffix and documented in Table 4-3 of the datasheet, which lists TLV3702CDGK as the packaged option for the 0°C to 70°C range - distinct from the industrial-grade "I" variant (TLV3702IDGK) rated for –40°C to 125°C.

How does the Power-On Reset (POR) function in TLV3702CDGKRG4?

The TLV3702CDGKRG4 incorporates an internal Power-On Reset circuit that holds both outputs low for up to 3 ms after VCC crosses 1.5 V during power-up. This ensures deterministic startup behavior and prevents false triggering during supply ramp-up. The POR is active only during power transitions and does not affect normal operation - a critical reliability feature in the TLV3702CDGKRG4's use in safety-aware portable systems.

Can TLV3702CDGKRG4 be used with a single 3.3 V supply?

Yes, TLV3702CDGKRG4 is fully specified for single-supply operation from 2.5 V to 16 V, including 3.3 V. At 3.3 V, it maintains 560 nA typical supply current, –0.1 V to 8.3 V input common-mode range, and push-pull output swing from <30 mV low to >3.2 V high (under light load). All electrical characteristics in Section 6.7 and 6.8 of the datasheet apply across this range - confirming robust functionality in the TLV3702CDGKRG4's 3.3 V designs.
