What are the key features of INA193AQDBVRRB?
- Wide -16 V to 80 V common-mode input range handles high-side sensing on 12 V, 24 V, and 48 V automotive rails
- 500 kHz bandwidth enables real-time current monitoring at switching frequencies in DC-DC converters
- AEC-Q100 qualified for -40°C to +125°C with reel tape-and-reel packaging for high-volume automotive assembly
What is INA193AQDBVRRB used for?
INA193AQDBVRRB is used in automotive battery management systems and motor-drive circuits where high-side current sensing across 12 V to 48 V rails is required without isolation. Its 500 kHz bandwidth makes it suitable for monitoring switch-mode power supplies and EV charging controllers. The compact 5-pin SOT-23 footprint fits space-constrained ECU and BMS PCBs.

Frequently Asked Questions
What common-mode voltage range does INA193AQDBVRRB support for high-side current sensing?
INA193AQDBVRRB accepts common-mode voltages from -16 V to 80 V, covering negative-to-ground transients and high-voltage bus rails up to 80 V. This range supports high-side sensing on 12 V, 24 V, and 48 V automotive battery buses while the single-supply output stays within a 2.7 V to 5.5 V logic rail.
How does INA193AQDBVRRB perform in a 48 V mild-hybrid battery monitoring application?
With a fixed 50 V/V gain and 500 kHz bandwidth, INA193AQDBVRRB directly monitors shunt resistor current on a 48 V mild-hybrid bus without differential amplifier external components. Its -40°C to +125°C AEC-Q100 Grade 1 rating ensures accuracy across the automotive temperature extremes found near battery pack enclosures.
What fixed gain does INA193AQDBVRRB provide, and how does it compare to other INA19x variants?
INA193AQDBVRRB provides a fixed 50 V/V gain. Within the INA19x family, INA190 offers 25 V/V and INA194 provides 100 V/V, so designers select INA193 when a mid-range gain best maps a 10 mΩ shunt's millivolt output to a 0 V to 5 V ADC input at currents up to 10 A.
What is the package and pin count for INA193AQDBVRRB, and how does it fit on a small PCB?
INA193AQDBVRRB ships in a 5-pin SOT-23 package measuring approximately 2.9 mm × 1.6 mm with 0.95 mm pitch, occupying under 5 mm² of board area. The tiny outline and only 5 pins simplify placement in compact automotive ECU designs where shunt sensing must be co-located with the sense resistor.
