Description
INA193AIDBVT is a Texas Instruments high-side current-sense monitor with a current-output interface. It senses the voltage drop across a low-value shunt resistor on the high side and converts the sensed current into a proportional output current, which you convert to a voltage with a pull-up resistor. It operates from a 2.7–5.5 V supply and tolerates a relatively high common-mode voltage (sensing above the supply) up to about 26 V, making it suitable for automotive/industrial sensing. The device features low input offset and fast response, enabling easy, high-impedance interfacing to ADCs. The AIDBVT suffix indicates an industrial-temperature grade part in an 8-pin DBV (VSSOP) package. Typical applications include battery and charger current monitoring, DC‑DC converter current sense, motor control, and general high-side current measurement in automotive and power‑supply systems.
Features
INA193AIDBVT is a high-side current-sense monitor with a current-output interface. Key features:
- High-side sensing across a shunt in the supply path.
- Wide input common-mode range suitable for monitoring large supply voltages.
- Single-supply operation and ease of ADC interfacing (Iout is proportional to Vshunt; use an external resistor to convert to a voltage for the MCU).
- Internal protection and fault handling (input/output protection and current limit to safeguard the device).
- Low offset and drift with good CMRR for accurate measurements over temperature.
- Small 8-pin package (DBV) for compact designs.
- Industrial temperature range (typical -40°C to 125°C).
Note: For exact electrical specs (ranges, gains, and limits), please refer to the TI INA193A datasheet.

Pinout
- Pin count: 8 pins (VSSOP-8 package, DBV).
- Function: High-side current-sense amplifier with a current-output. It senses the differential voltage across a shunt resistor on the high side and produces a current proportional to the sensed current at its output pin; the current is converted to voltage externally (via a sense resistor).
