Product details
Overview
TLV3701CDBVTG4 from Texas Instruments is a single-channel 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, draws only 560 nA per channel, supports input common-mode voltage up to VCC + 5 V, and features reverse-battery protection up to 20 V - enabling direct use in portable medical monitors and handheld instrumentation.
For engineers reviewing the TLV3701CDBVTG4 datasheet, TLV3701CDBVTG4 pinout, TLV3701CDBVTG4 application, or TLV3701CDBVTG4 equivalent, key selection criteria include its 560 nA supply current, rail-to-rail input range extending beyond VCC, push-pull output eliminating external pull-up needs, and SOT-23-5 packaging for space-constrained PCBs.
Technical Context
The TLV3701CDBVTG4 implements a precision nanopower comparator core with internal power-on-reset (POR) that holds output low for ≤3 ms during VCC ramp-up. Its input stage supports two operating modes: within-rail (bias current <1 pA at low common-mode) and over-rail (up to VCC + 5 V, bias current ~55 nA), enabling robust threshold detection even when inputs exceed supply voltage.
It integrates ESD protection clamps, fail-safe inputs functional down to –0.1 V and up to 16 V independent of VCC, and a push-pull output stage capable of sourcing/sinking ≥50 µA while maintaining VOL ≤ 80 mV and VOH ≥ VCC – 320 mV across temperature and supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 560 nA per channel - enables multi-year operation on coin-cell batteries in always-on monitoring circuits |
| Input common-mode range | –0.1 V to VCC + 5 V - allows direct sensing of voltages exceeding supply rail without external level-shifting |
| Propagation delay | 16 µs (high-to-low, 50 mV overdrive) - sufficient for slow-varying battery voltage or temperature thresholds |
| Input offset voltage | 250 µV typical (max 5 mV) - supports accurate 1% threshold detection in precision sensor interfaces |
| Output type | Push-pull CMOS - eliminates need for external pull-up resistor, reducing BOM count and standby power |
| Reverse battery protection | Withstands –20 V on VCC - prevents damage from incorrect battery insertion in consumer handhelds |
| Operating temperature | 0°C to 70°C - qualified for commercial-grade portable electronics applications |
Pinout & Package
TLV3701CDBVTG4 is housed in a 5-pin SOT-23 package (2.9 mm × 2.8 mm), optimized for high-density portable PCB layouts. The device uses a standard pinout compatible with TI's universal op-amp evaluation modules.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | CMOS push-pull output - drives logic-high or logic-low directly without external components |
| 2 | GND | Analog ground reference - must connect to low-impedance system ground plane to minimize noise coupling |
| 3 | IN+ | Noninverting input - accepts signals from 0 V to VCC + 5 V; high-impedance (>300 MΩ) minimizes loading |
| 4 | IN− | Inverting input - matched to IN+ for differential threshold detection; supports same over-rail range |
| 5 | VCC | Positive supply rail - accepts 2.5 V to 16 V; internal POR activates below 1.5 V to ensure known startup state |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 560 nA per channel - extends battery life in always-on wearable sensors and remote monitors |
| Over-rail input capability | Inputs functional up to VCC + 5 V - enables direct battery voltage monitoring without resistive dividers |
| Fail-safe inputs | Operational with VCC unpowered - prevents latch-up or leakage during power sequencing in multi-rail systems |
| Integrated power-on reset | Holds OUT low for ≤3 ms at power-up - eliminates spurious output transitions during supply ramp |
| Reverse battery tolerance | Withstands –20 V on VCC pin - protects against user-induced polarity reversal in consumer devices |

FAQ
What is the maximum input voltage allowed on the IN+ and IN− pins of the TLV3701CDBVTG4?
The TLV3701CDBVTG4 supports an input common-mode voltage range from –0.1 V to VCC + 5 V. This means that when powered from 5 V, inputs may safely reach up to 10 V. Absolute maximum rating is ±20 V differential or 16 V absolute, whichever is smaller - ensuring compatibility with battery voltage monitoring above supply rails. This specification applies directly to the TLV3701CDBVTG4 under recommended operating conditions.
Does the TLV3701CDBVTG4 require an external pull-up resistor on its output?
No, the TLV3701CDBVTG4 features a push-pull CMOS output stage that actively drives both high and low states. Unlike open-drain comparators, it does not require an external pull-up resistor - reducing component count, board area, and standby power consumption. This behavior is confirmed in the device's functional block diagram and electrical characteristics table for VOH and VOL. The TLV3701CDBVTG4 delivers this capability in its 5-pin SOT-23 package.
What is the power-on reset (POR) behavior of the TLV3701CDBVTG4?
The TLV3701CDBVTG4 incorporates an internal power-on-reset circuit that holds the OUT pin low for up to 3 ms after VCC crosses 1.5 V during power-up. This ensures a known, glitch-free startup state regardless of input conditions. The POR function is active across the full operating temperature range and is intrinsic to the TLV3701CDBVTG4 die design - no external components are needed to implement reliable initialization.
Can the TLV3701CDBVTG4 operate from a 2.5-V supply?
Yes, the TLV3701CDBVTG4 is fully specified to operate from a minimum supply voltage of 2.5 V over the commercial temperature range (0°C to 70°C). At 2.5 V, it maintains 560 nA typical supply current, functional over-rail inputs (up to 7.5 V), and valid output swing (VOL ≤ 300 mV, VOH ≥ 2.05 V). All key parameters in the datasheet - including propagation delay and offset voltage - are guaranteed at 2.5 V for the TLV3701CDBVTG4.
Is the TLV3701CDBVTG4 pin-compatible with other members of the TLV370x family?
The TLV3701CDBVTG4 in SOT-23-5 is pin-compatible only with other TLV3701 variants (e.g., TLV3701CDBVR, TLV3701IDBVT) in the same package. It is not pin-compatible with TLV3702 (8-pin MSOP/SOIC) or TLV3704 (14-pin TSSOP/SOIC/PDIP), which have different channel counts and pinouts. Pin compatibility for the TLV3701CDBVTG4 is strictly limited to the 5-pin SOT-23 footprint defined in Figure 5-1 of the datasheet.
