Product details
Overview
LT1716HS5#TRMPBF from Analog Devices is a micropower, precision rail-to-rail comparator with Over-the-Top® input stage enabling operation with inputs up to 44V above V–, independent of V+. It draws only 35µA quiescent current, delivers rail-to-rail output swing (within 35mV of V– and 55mV of V+), and operates across 2.7V to 44V supply range. It is used in lamp monitors, relay drivers, and power supply supervisors requiring high common-mode tolerance and low-power precision.
For engineers reviewing the LT1716HS5#TRMPBF datasheet, LT1716HS5#TRMPBF pinout, LT1716HS5#TRMPBF application, or LT1716HS5#TRMPBF equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for automotive-grade high-voltage comparator selection.
Technical Context
The LT1716HS5#TRMPBF employs a three-stage input architecture (NPN/PNP/common-base) enabling seamless operation across wide common-mode ranges-from 0.5V above V– to 44V above V–-with no phase reversal even when one input drops 5V below V–. Its internal pull-up current source eliminates external pull-up resistors while maintaining open-collector-like functionality for driving loads referenced to higher supplies.
It features built-in 5kΩ input protection resistors limiting fault current to ≤1mA during –5V-to-V– excursions, and supports full temperature operation from –40°C to +125°C per AEC-Q100 qualification. Propagation delay is 6µs typical at 100mV overdrive into 10kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 44V total - enables single-supply operation in 3.3V, 5V, 12V, 24V, and 48V systems without level-shifting. |
| Input Common-Mode Range | Extends 44V above V–, independent of V+ - allows direct sensing of high-side voltages (e.g., battery, bus) without attenuators. |
| Quiescent Current | 35µA max - supports always-on monitoring in battery-powered or energy-sensitive applications like automotive body control modules. |
| Input Offset Voltage | 1.6mV max over –40°C to +125°C - ensures stable threshold detection under extreme thermal conditions. |
| Output Swing | Within 35mV of V– and 55mV of V+ - delivers usable logic levels even at low supply voltages (e.g., 3V operation). |
| Propagation Delay | 6µs typical at 100mV overdrive - suitable for medium-speed event detection (e.g., overvoltage flagging, lamp burn-out detection). |
| Operating Temperature | –40°C to +125°C - qualified per AEC-Q100 Grade H for under-hood and powertrain applications. |
Pinout & Package
LT1716HS5#TRMPBF is housed in a 5-lead TSOT-23 (S5) package - low-profile (1mm height), JEDEC MO-193 compliant, with 0.95mm pitch and 1.90mm × 2.80mm footprint. Designed for space-constrained automotive and industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Push-pull output with internal pull-up | Drives logic loads directly; sinks current to V– and sources current via internal ~60µA pull-up - no external resistor needed. |
| 2 (V–) | Negative supply rail | Reference for all internal circuitry; inputs tolerate –5V relative to this pin; output swings to within 35mV of this node. |
| 3 (+IN) | Noninverting input | Accepts common-mode voltage from 0.5V to 44V above V–; protected by 5kΩ series resistor against –5V faults. |
| 4 (–IN) | Inverting input | Same voltage range and protection as +IN; differential input voltage rating is ±44V. |
| 5 (V+) | Positive supply rail | Supplies internal bias; device shuts down if removed; reverse-battery protected up to 20V. |
Key Features
| Feature | Design Value |
|---|---|
| Over-the-Top® Input Stage | Enables direct high-side sensing (e.g., 48V bus monitoring) without external resistive dividers or level shifters. |
| Internal Pull-Up Current Source | Eliminates external pull-up resistor, reducing BOM count and board area while saving power vs. passive pull-ups. |
| Rail-to-Rail Output Swing | Delivers full logic swing across supply range - critical for interfacing with 3.3V/5V microcontrollers in low-voltage systems. |
| –5V Below V– Fault Tolerance | Guarantees valid output and no phase reversal when either input falls to –5V relative to V–, supported by on-chip 5kΩ resistors. |
| AEC-Q100 Qualified (Grade H) | Validated for automotive applications including engine control, lighting, and battery management systems operating at 125°C junction. |
Applications
| Lamp Monitor | Power Supply Supervisor |
|---|---|
Use Scenario: Detecting open-circuit or filament failure in automotive headlamps or cabin lighting powered from 12V/24V battery rails. IC Role / Device Role / Timing Role: Comparator compares lamp voltage drop across sense resistor against reference; triggers fault signal on OUT pin.

| Relay Driver Interface | Oscillator / Window Detector |
Use Scenario: Driving opto-isolated or MOSFET-based relay control circuits in HVAC or motor control panels. IC Role / Device Role / Timing Role: Provides clean, rail-compatible logic-level output to gate driver or isolation input, tolerant of supply ripple and noise. Use Value: Output drives loads referenced to higher voltage than V+, supporting isolated feedback paths and robust noise immunity. | Use Scenario: Building hysteresis-based oscillators or dual-threshold window detectors for battery charge-state indication. IC Role / Device Role / Timing Role: Configured with positive feedback to generate square wave; or used with dual references to detect voltage in/out of safe band. Use Value: Micropower operation (35µA) extends battery life; rail-to-rail swing ensures reliable logic transitions across full supply range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1719HS5#TRMPBF | Faster propagation delay (4.5ns vs 6µs), higher supply current (1.2mA), no Over-the-Top® input - requires external level shifting for >V+ inputs. | Better suited for high-speed digital interface monitoring; not suitable for direct high-side sensing above V+. | Select LT1719HS5#TRMPBF only when speed >1MHz is required and input common-mode stays within supply rails. |
| TLV3701QDBVRQ1 | Automotive-qualified (AEC-Q100), lower IQ (1µA), but limited input range (V– to V+ +0.2V); no –5V fault tolerance. | Optimized for ultra-low-power wake-up detection in battery-off mode; lacks Over-the-Top® capability for high-voltage sensing. | Choose TLV3701QDBVRQ1 for standby-current-critical applications where input stays within rail limits and speed is secondary. |
Compared with LT1716HS5#TRMPBF, LT1719HS5#TRMPBF trades micropower and Over-the-Top® operation for nanosecond-speed response, while TLV3701QDBVRQ1 sacrifices high-voltage input flexibility for sub-microamp quiescent current - making LT1716HS5#TRMPBF uniquely balanced for automotive power monitoring where both precision, fault tolerance, and low power matter.

Does LT1716HS5#TRMPBF require an external pull-up resistor on the output?
No, LT1716HS5#TRMPBF does not require an external pull-up resistor. Its output stage includes an internal class-B pull-up current source (~60µA typical), allowing direct connection to logic inputs or loads referenced to higher supplies - a key feature explicitly documented in the DESCRIPTION and OUTPUT sections of the datasheet.
Is LT1716HS5#TRMPBF qualified for automotive applications?
Yes, LT1716HS5#TRMPBF is AEC-Q100 qualified for automotive applications (Grade H), with guaranteed operation from –40°C to +125°C. The datasheet's ORDER INFORMATION table explicitly lists it as an automotive product, and the FEATURES section confirms AEC-Q100 qualification - distinct from commercial-grade C/I variants.
What is the typical propagation delay of LT1716HS5#TRMPBF?
The typical propagation delay of LT1716HS5#TRMPBF is 6µs at 100mV overdrive into a 10kΩ load, as specified in the ELECTRICAL CHARACTERISTICS table for the LT1716H grade. This value applies across the full –40°C to +125°C operating range and is validated in the Typical Performance Characteristics (Figure G13–G16).
Can LT1716HS5#TRMPBF operate with a single 3.3V supply?
Yes, LT1716HS5#TRMPBF operates with a minimum supply voltage of 2.7V, making it fully compatible with 3.3V single-supply systems. Its rail-to-rail output swings to within 35mV of V– and 55mV of V+, delivering usable logic-high/low levels for interfacing with 3.3V microcontrollers - confirmed in the FEATURES and ELECTRICAL CHARACTERISTICS tables.
