Product details
Overview
LT6703HVHS5-2#TRMPBF from Analog Devices (acquired Linear Technology) is an inverting-input micropower supply voltage monitor comparator with integrated 400mV reference, 6.5μA quiescent current, ±15nA input bias current, and open-collector output rated to 36V. It operates from 1.4V to 18V supply and supports –40°C to 125°C industrial/automotive applications including battery monitoring and relay driving.
For engineers reviewing the LT6703HVHS5-2#TRMPBF datasheet, LT6703HVHS5-2#TRMPBF pinout, LT6703HVHS5-2#TRMPBF application, or LT6703HVHS5-2#TRMPBF equivalent, key selection criteria include its inverting input polarity, 36V output voltage tolerance, built-in 6.5mV hysteresis, 400mV reference accuracy (±1.25% max at 25°C), and TSOT-23-5 package compatibility with high-side sensing and level-translating designs.
Technical Context
The LT6703HVHS5-2#TRMPBF implements a single-channel, inverting-input comparator architecture with Over-The-Top® input stage enabling operation down to ground and up to 36V independent of VS. Its internal 400mV reference sets the rising threshold at ≈400mV and falling threshold at ≈393.5mV, yielding 6.5mV typical hysteresis for noise immunity without external feedback.
It features an open-collector output capable of sinking ≥5mA while supporting off-state voltages up to 36V referenced to GND - decoupled from the 1.4V–18V supply rail. Input bias current remains ≤±15nA across –40°C to 125°C, and propagation delay is 18μs (HL) / 29μs (LH) under 10mV overdrive conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Rising Threshold Voltage | 392–408 mV at 25°C; defines precise low-voltage detection point for supply monitoring |
| Hysteresis | 2–11.5 mV over –40°C to 125°C; prevents chatter during slow-rising/falling inputs |
| Supply Current | 15 μA max at 5V over full temperature range; enables multi-year battery life in portable systems |
| Input Bias Current | ±15 nA max over –40°C to 125°C; minimizes error in high-impedance divider networks |

Pinout & Package
LT6703HVHS5-2#TRMPBF uses a 5-lead Plastic TSOT-23 (S5) package with exposed pad grounded per datasheet. Pin 1 = OUT, Pin 2 = GND, Pin 3 = –IN, Pin 4 = VS, Pin 5 = NC (no connection). The exposed pad must be soldered to PCB for thermal and electrical grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| GND (Pin 2) | Ground reference and reference low side | Return path for internal 400mV reference and output sink current |
| –IN (Pin 3) | Inverting input terminal | Voltage applied here triggers output low when >400mV; enables high-side supply monitoring |
| VS (Pin 4) | Positive supply input | 1.4V–18V operation; powers internal circuitry and reference; bypass capacitor required |
| NC (Pin 5) | No internal connection | Not bonded; must remain unconnected and unpopulated on PCB |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar supply voltage monitor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6703HVCS5-2#TRMPBF | Same functionality and pinout; differs only in temperature grade (0°C to 70°C vs –40°C to 125°C) | Not suitable for automotive or extended-temperature industrial use | Select if operating environment stays within commercial temperature range and cost optimization is critical |
| TLV7032DRYR | Lower supply voltage (1.6V min), no integrated reference, requires external 400mV source; 5-pin X2SON package | Lacks built-in reference and 36V output capability; limited to low-voltage, space-constrained designs | Choose only when board space is severely constrained and external reference is already present |
Compared with LT6703HVCS5-2#TRMPBF and TLV7032DRYR, the LT6703HVHS5-2#TRMPBF uniquely combines automotive-grade temperature range, integrated 400mV reference, and 36V output tolerance in a standard TSOT-23 footprint - eliminating design compromises in harsh-environment supply supervision.

FAQ
What is the function of the NC pin (Pin 5) on the LT6703HVHS5-2#TRMPBF?
Pin 5 is a no-connect terminal with no internal bond wire or circuit connection. It must remain unconnected on the PCB and should not be tied to GND, VS, or any other node. Leaving it floating is electrically safe and matches the manufacturer's recommended layout per datasheet Figure 13.
Can the LT6703HVHS5-2#TRMPBF monitor a 24V supply using a simple resistor divider?
Yes. The LT6703HVHS5-2#TRMPBF supports input voltages up to 36V on the –IN pin regardless of VS. A resistor divider scaling 24V to 400mV (e.g., 59kΩ top / 1kΩ bottom) enables direct high-side monitoring without level-shifting circuitry, leveraging the device's Over-The-Top® input architecture.
What is the maximum sink current guaranteed for the LT6703HVHS5-2#TRMPBF output?
The LT6703HVHS5-2#TRMPBF output guarantees ≥5mA sink current over the full –40°C to 125°C temperature range when VOL is measured at 200mV. At 25°C, typical sink capability exceeds 40mA, but design margin should be based on the 5mA minimum specification for robustness.
Does the LT6703HVHS5-2#TRMPBF require an external bypass capacitor?
Yes. A minimum 0.1μF ceramic capacitor must be placed between VS and GND, close to the device pins. For loads sinking >5mA or in noisy supply environments, a 1μF capacitor is recommended. This ensures stable reference and comparator operation by suppressing supply rail transients.
How does the hysteresis of the LT6703HVHS5-2#TRMPBF affect threshold accuracy?
The LT6703HVHS5-2#TRMPBF provides 2–11.5mV hysteresis over temperature, creating distinct rising (≈400mV) and falling (≈393.5mV) thresholds. This intentional offset prevents oscillation near the trip point due to noise or slow-moving signals, improving system reliability without requiring external positive feedback components.
