Product details
Overview
TLV3702IP 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 reverse battery protection up to 20V - enabling reliable voltage monitoring in portable medical devices and handheld instruments.
For engineers reviewing the TLV3702IP datasheet, TLV3702IP pinout, TLV3702IP application, or TLV3702IP equivalent, key selection criteria include its industrial-grade temperature range (–40°C to 125°C), rail-overlapping inputs, propagation delay under 50 µs at 10 mV overdrive, and compatibility with single-supply 5V/12V systems requiring no external pull-up.
Technical Context
The TLV3702IP integrates two independent comparators sharing a common VCC and GND, each with fail-safe inputs capable of operating 5V above the positive rail without damage. Its internal power-on-reset circuit holds outputs low for ≤3 ms during supply ramp-up, ensuring deterministic startup behavior in energy-constrained systems.
Input bias current remains below 250 pA across the full common-mode range, while the push-pull output delivers VOH ≥ VCC – 450 mV and VOL ≤ 300 mV at ±50 µA load - eliminating need for external pull-up resistors and reducing system-level power overhead.

| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Push-pull output for comparator channel 1 - drives logic-high or logic-low directly without external components |
| 2 | 1IN− | Inverting input for channel 1 - accepts signals up to VCC + 5V, enabling high-side voltage sensing |
| 3 | 1IN+ | Noninverting input for channel 1 - used with reference voltage or feedback network for threshold comparison |
| 4 | GND | Analog ground reference - must be connected to system ground plane to maintain input bias current stability |
| 5 | 2IN+ | Noninverting input for channel 2 - independent of channel 1, supports dual-threshold or window-comparator topologies |
| 6 | 2IN− | Inverting input for channel 2 - supports differential sensing or inverted logic polarity per channel |
| 7 | 2OUT | Push-pull output for comparator channel 2 - electrically isolated from 1OUT; enables independent control paths |
| 8 | VCC | Positive supply input - accepts 2.5V–16V; internal reverse-battery protection guards against –20V misconnection |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702IDGK | Same electrical specs; MSOP-8 package (3 mm × 4.9 mm) vs. PDIP-8 (10.2 mm × 9.4 mm) | Preferred for space-constrained PCBs; requires surface-mount assembly and reflow profile control | Select TLV3702IDGK for volume production with automated SMT lines; TLV3702IP retains advantage in manual assembly, test fixtures, and legacy designs. |
| TLC3702CD | Higher supply current (470 nA vs. 560 nA), wider VIO (1200 µV typ), open-drain output requiring pull-up | Lacks rail-overlapping inputs and reverse-battery protection; unsuitable for high-side sensing or harsh battery environments | Choose TLC3702CD only if board area is constrained and open-drain logic interface is required; otherwise TLV3702IP offers superior input flexibility and protection. |

FAQ
What is the maximum input voltage allowed on TLV3702IP pins?
The TLV3702IP supports input voltages from –0.1V to VCC + 5V, with absolute maximum rating of ±20V differential and 16V common-mode relative to GND. This means inputs can safely exceed the supply rail by up to 5V - a key enabler for high-side battery voltage monitoring without level shifters. The device also withstands –20V on VCC due to integrated reverse-battery protection.
Does TLV3702IP require external pull-up resistors on its outputs?
No, TLV3702IP does not require external pull-up resistors because it features a push-pull CMOS output stage. Each output actively drives high (to within 450 mV of VCC) and low (to within 300 mV of GND) under ±50 µA load. This eliminates standby current through pull-up resistors and reduces component count - critical for nanopower system design.
What is the operating temperature range of TLV3702IP?
TLV3702IP is rated for industrial operation from –40°C to +125°C. This range is confirmed in Table 4-3 of the datasheet and applies to all electrical specifications unless otherwise noted. The "I" suffix denotes industrial grade, distinguishing it from commercial-grade variants (e.g., TLV3702CD) limited to 0°C–70°C.
How does the power-on-reset (POR) function in TLV3702IP?
The TLV3702IP incorporates an internal POR circuit that holds both outputs low for ≤3 ms after VCC crosses 1.5V during power-up or brown-out recovery. This ensures deterministic initial state before the comparators become active, preventing spurious logic transitions in downstream microcontrollers or latches. The POR is fully integrated - no external components needed.
Can TLV3702IP operate from a 2.5V supply?
Yes, TLV3702IP is fully specified down to 2.5V single supply (or ±1.25V dual supply) across its entire temperature range. At 2.5V, it maintains 560 nA per channel supply current, –0.1V to 7.5V input common-mode range, and functional push-pull outputs - enabling direct use in low-voltage energy-harvesting and coin-cell applications without LDO regulation.
