Frequently Asked Questions
What reference voltage is integrated in the LT6703HDC-3#TRMPBF and how does it simplify circuit design?
The LT6703HDC-3#TRMPBF integrates a precision 400 mV internal reference, removing the need for an external voltage reference or resistor divider in most threshold detection circuits. This reduces component count and board area in battery voltage monitoring, supply supervision, and low-power comparator applications.
What is the input bias current of the LT6703HDC-3#TRMPBF and why is it important?
The LT6703HDC-3#TRMPBF has a maximum input bias current of 10 nA, which is extremely low. This allows accurate comparisons with high-impedance signal sources such as resistor dividers, thermistors, or photodiode circuits without introducing significant offset errors from input loading effects.
What supply voltage range does the LT6703HDC-3#TRMPBF support and what applications does it enable?
The LT6703HDC-3#TRMPBF operates from 1.4 V to 18 V supply voltage, covering single-cell battery systems at 1.5 V, coin cell applications at 3 V, and industrial 12 V or 15 V rails. This wide range makes it versatile across portable electronics, battery management systems, and industrial monitoring circuits.
What output type does the LT6703HDC-3#TRMPBF use and how is it connected to a microcontroller?
The LT6703HDC-3#TRMPBF features an open-collector output requiring an external pull-up resistor, typically 10 kΩ to 100 kΩ, connected to the logic supply rail. This allows direct interfacing to 3.3 V or 5 V microcontroller GPIO inputs and enables wired-OR connections with multiple comparator outputs.
How compact is the LT6703HDC-3#TRMPBF package and when is it preferred over standard SOT-23-5 comparators?
The LT6703HDC-3#TRMPBF uses a 3-pin SOT-23 (SC-70) package, smaller than the 5-pin SOT-23-5 used by many standalone comparators. When only a single threshold comparison with built-in 400 mV reference is needed, the 3-pin package saves board space and simplifies routing in wearable and IoT sensor designs.
