Key Features
- Single comparator with 18 V maximum supply rating and only 0.01 µA input bias current for high-impedance threshold detection
- Open-collector output enabling wired-OR logic configurations and flexible pull-up voltage selection up to 18 V
- Ultra-compact 3-pin DFN-EP package minimizing PCB footprint for automotive under-hood space-constrained comparator circuits
Applications
The LT6703IDC-2#TRMPBF is designed for automotive and industrial threshold detection applications where a tiny PCB footprint is essential, such as battery cell overvoltage monitoring, MOSFET gate drive enable circuits, and power-good indicators. Its open-collector output allows direct interface with different logic voltage rails up to 18 V, simplifying level-shifting in mixed-voltage supervisory circuits. The extremely low 0.01 µA input bias current makes it suitable for resistive divider networks with high source impedances without corrupting threshold accuracy.

Frequently Asked Questions
How does the 0.01 µA maximum input bias current of the LT6703IDC-2#TRMPBF benefit high-impedance resistive divider threshold circuits?
With a maximum input bias current of only 0.01 µA, the LT6703IDC-2#TRMPBF draws negligible current from resistive voltage dividers even when using 1 MΩ or larger resistors, causing less than 10 mV of threshold error. This allows the use of high-value resistors to reduce quiescent current in battery-operated automotive supervisory circuits without sacrificing threshold accuracy across the operating temperature range.
What wiring flexibility does the open-collector output provide when integrating the LT6703IDC-2#TRMPBF into a mixed-voltage 18 V automotive system?
The open-collector output of the LT6703IDC-2#TRMPBF allows the external pull-up resistor to be connected to any supply voltage up to 18 V, independent of the comparator's own supply. This means a 3.3 V microcontroller input can directly receive the comparator output even when the comparator monitors a 12 V automotive battery rail, eliminating the need for a separate level-shifting circuit.
When is the 3-pin DFN-EP package of the LT6703IDC-2#TRMPBF preferred over a standard SOT-23 comparator in automotive PCB designs?
The 3-pin DFN-EP package of the LT6703IDC-2#TRMPBF occupies less PCB area than a SOT-23 with a comparable footprint height, making it the preferred choice when placing multiple comparators near MOSFET gate drivers or battery management ICs where board space is measured in fractions of a square millimeter. Its exposed pad also aids thermal management in under-hood automotive environments reaching up to 125°C ambient.
