概述

Description

INA193AIDBVT is a high-side current-sense amplifier in an 8-pin DBV package. It measures the small voltage across a shunt resistor in the supply path and outputs a voltage proportional to the load current, enabling a microcontroller to monitor current. The AIDBVT suffix denotes the device variant and package/temperature grade (A = extended temperature). Key features typically include bidirectional sensing, wide input common-mode range, single-supply operation, low offset, and fast response. Typical connections: place the shunt between Vin and the load, connect S+ to the high-side node and S− to the low-side node, supply Vcc, and use REF to set the output baseline; Vout then equals Vref plus Gain × Vshunt. Applications: power-management, battery charging, motor control, and general current monitoring. For exact specs (range, gain, output swing, supply, and package dimensions), consult the INA193 datasheet.

Features

Here are key features of the INA193AIDBVT (TI current-sense amplifier):
- High-side current-sense amplifier for sensing shunt voltage
- Wide input/common-mode range suitable for high-side sensing (up to tens of volts)
- Single-supply operation (compact 2.7–5.5 V rail)
- Fixed internal gain for direct shunt-to-output conversion
- Rail-to-rail output to interface with common ADCs
- Low input offset voltage and low drift for accurate measurements
- Low quiescent current for power-sensitive applications
- 8-pin VSSOP package (DBV) for compact layouts
- Industrial temperature range (typical) suitable for varied environments
- Protective features and robust ESD/short‑circuit tolerance
Note: For exact electrical specifications (gain, exact voltage ranges, offsets, and temperature range), refer to the datasheet.

Package

INA193AIDBVT uses the DBV package, i.e., VSSOP‑8. The trailing “T” indicates Tape & Reel packaging.

Pinout

- Pin count: 8 pins in a VSSOP-8 package (DBV/AIDBVT).
- Function: High-side current-sense amplifier with a current-output. It senses voltage across a shunt resistor and provides an output current proportional to the sensed load current, which is converted to a voltage with an external resistor. Used for monitoring current on power rails.
