Overview
The LT6703HVHS5-2#TRPBF is a micropower analog comparator featuring an internal 400mV reference, housed in a 5-lead TSOT-23 package. It operates on a single supply voltage ranging from 1.4V to 18V with a typical quiescent current of 6.5μA at 5V. The device provides an open-collector output capable of sinking up to 40mA and supports input voltages up to 36V independent of the supply rail. It includes built-in hysteresis for noise immunity and is specified for operation across a temperature range of –40°C to 125°C.
Feature Summary
- Integrates a precise 400mV internal reference with an inverting input configuration
- Supports Over-The-Top inputs and outputs extending up to 36V regardless of supply voltage
- Features low quiescent current consumption suitable for battery-powered applications
- Includes internal hysteresis to ensure stable switching under noisy conditions
Applications
- Battery-powered system monitoring
- Threshold detectors and window comparators
- Relay driving circuits
- Industrial control systems
- Automotive monitor and controls
Procurement Notes
Verify the specific suffix HVS5-2 corresponds to the TSOT-23 package and industrial/automotive temperature grade when sourcing. Confirm that the HV designation is required for your application due to the extended 36V input/output capability compared to standard variants. Ensure compatibility with the inverting input polarity (LT6703-2) versus non-inverting options if design constraints change.
Selection Notes
Select this component when high-voltage signal monitoring is required from a low-voltage supply rail. The 36V input tolerance allows direct connection to higher voltage nodes without external dividers in some cases. The inverting input type dictates the logic response relative to the 400mV threshold. Consider the TSOT-23 footprint constraints against available PCB space.
Part Context
This part belongs to the LT6703 family of micropower comparators. The 'HV' variant specifically denotes enhanced voltage handling capabilities for both inputs and outputs. The 'H' indicates the extended temperature range, while 'S5' identifies the small outline transistor package. It serves as a compact solution for voltage supervision tasks where power efficiency and high-voltage interface are critical.

FAQ
What is the maximum voltage allowed on the input pins?
The input pins can withstand voltages up to 36V with respect to ground, independent of the supply voltage.
Does this comparator have adjustable hysteresis?
No, it features fixed internal hysteresis of approximately 6.5mV typ. External circuitry can be added to increase effective hysteresis.
What is the difference between the LT6703-2 and LT6703-3 versions?
The LT6703-2 has an inverting external input, while the LT6703-3 has a non-inverting external input. Both share the same internal 400mV reference.
