Product details
Overview
LT1716HS5#TRPBF from Analog Devices is a micropower, precision rail-to-rail comparator with Over-the-Top® input capability, operating from 2.7V to 44V supply and drawing only 35µA quiescent current. Its inputs withstand 44V common-mode voltage above V– (independent of V+), output swings within 35mV of V– and 55mV of V+, and it features internal pull-up current sourcing - enabling direct drive of loads referenced to higher supplies. It is used in automotive lamp monitors and high-side power supply supervisors where fault-tolerant input operation is critical.
For engineers reviewing the LT1716HS5#TRPBF datasheet, LT1716HS5#TRPBF pinout, LT1716HS5#TRPBF application, or LT1716HS5#TRPBF equivalent, key selection considerations include its –40°C to 125°C guaranteed operating range, 44V over-the-top input tolerance, 1.6mV max input offset voltage at temperature, rail-to-rail output swing, and SOT-23-5 package compatibility with space-constrained industrial and automotive PCBs.
Technical Context
The LT1716HS5#TRPBF 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–, including 5V below V– without phase reversal. Its unique input stage eliminates external clamping while maintaining precision via built-in 5kΩ protection resistors per input.
The output stage integrates a class-B pull-up current source (60–110µA typical), eliminating external pull-up resistors and supporting open-collector-like operation - driving loads referenced up to 44V above V–. Propagation delay is 6–9µs with 100mV overdrive into 10kΩ load, and large-signal gain exceeds 200 V/mV under single-supply conditions.

Applications
| Lamp Monitor | Power Supply Supervisor |
|---|---|
|
Use Scenario: Monitoring incandescent or LED lamp status in automotive lighting modules, detecting open-circuit or short-circuit failures. IC Role / Device Role / Timing Role: Comparator compares lamp voltage drop across sense resistor against reference; triggers fault flag on deviation. Use Value: Leverages 44V Over-the-Top® input to directly sense lamp voltage without isolation, and rail-to-rail output drives microcontroller GPIO directly. |
Use Scenario: Supervising 12V/24V/42V vehicle battery or DC-DC converter output for undervoltage/overvoltage conditions. IC Role / Device Role / Timing Role: Compares monitored rail against precision reference (e.g., LT1634); asserts fault signal when out-of-spec. Use Value: Operates across full battery range (2.7V–44V) and survives cold-crank transients; internal protection avoids external TVS diodes. |
| Relay Driver Interface | Peak Detector Circuit |
|
Use Scenario: Controlling high-side relay drivers in body electronics, ensuring activation only when supply meets minimum threshold. IC Role / Device Role / Timing Role: Comparator detects when system voltage exceeds relay coil turn-on threshold; output directly drives gate/base driver. Use Value: Output's ability to drive loads referenced to higher supply allows direct interface with N-channel high-side switches without level shifters. |
Use Scenario: Capturing peak voltage of pulsed signals in battery management or sensor conditioning circuits. IC Role / Device Role / Timing Role: Comparator enables diode-based peak hold by triggering reset when input falls below stored peak. Use Value: Low 35µA quiescent current minimizes leakage error in hold capacitor; rail-to-rail output ensures full dynamic range utilization. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1719CS6#TRMPBF | Faster propagation delay (4.5ns vs 6–9µs), but limited 5.5V max supply and no Over-the-Top® input - requires level shifting for >5.5V sensing. | Better suited for high-speed digital threshold detection; unsuitable for direct 12V+ rail monitoring. | Select LT1719 only when speed >1MHz is required and input voltage stays below 5.5V. |
| TLV3701IDBVR | Lower quiescent current (1µA), but only 16V max supply and ±0.5V input range relative to rails - lacks fault tolerance below V–. | Optimized for ultra-low-power portable devices; cannot replace LT1716HS5#TRPBF in automotive or industrial high-voltage monitoring. | Choose TLV3701 only for battery-powered systems with supply ≤16V and no sub-rail fault requirements. |
Compared with LT1719CS6#TRMPBF and TLV3701IDBVR, the LT1716HS5#TRPBF uniquely combines 44V Over-the-Top® input, –40°C to 125°C operation, and internal pull-up - making it irreplaceable for robust, high-voltage automotive supervision where fault resilience and simplicity are mandatory.

FAQ
What is the maximum input voltage the LT1716HS5#TRPBF can tolerate relative to V–?
The LT1716HS5#TRPBF supports an input common-mode voltage up to 44V above V–, independent of the V+ supply voltage. This Over-the-Top® capability allows direct sensing of high-side voltages - such as 42V automotive battery rails - without external level-shifting circuitry. The device also tolerates inputs 5V below V– without phase reversal, thanks to internal 5kΩ protection resistors.
Does the LT1716HS5#TRPBF require an external pull-up resistor on its output?
No, the LT1716HS5#TRPBF does not require an external pull-up resistor. Its output stage includes an integrated class-B pull-up current source (60–110µA typical), enabling direct drive of logic inputs or higher-voltage loads. This eliminates board space, reduces power loss, and simplifies design - especially in high-side switching interfaces where the load may be referenced to a supply more positive than V+.
Is the LT1716HS5#TRPBF qualified for automotive applications?
Yes, the LT1716HS5#TRPBF is AEC-Q100 qualified (Grade H) and specified for operation from –40°C to 125°C. It is explicitly designated for automotive use in the manufacturer's ordering information and meets stringent reliability and thermal performance requirements for under-hood and body electronics applications such as lamp monitoring and battery supervision.
What is the typical propagation delay of the LT1716HS5#TRPBF?
The LT1716HS5#TRPBF has a propagation delay of 6µs minimum to 9µs maximum under standard test conditions (100mV overdrive, 10kΩ load). This delay remains stable across its full –40°C to 125°C operating range and 2.7V–44V supply range, making it suitable for medium-speed supervision tasks where deterministic response time matters - such as power-good signaling or fault flag assertion.
Can the LT1716HS5#TRPBF operate with one input below the negative supply rail?
Yes, the LT1716HS5#TRPBF is designed to operate with either input driven up to 5V below V– without output phase reversal. Internal 5kΩ series resistors limit input current to 1mA at –5V, providing robust fault protection. This capability is essential for detecting ground faults, reverse-battery conditions, or sensor disconnections in automotive and industrial systems.
